    Hi Guys!
    I’ve just searched the site for inspiration as well as for solutions and I’ve seen many interesting projects. Especially, I’m talking about some beautiful Café Racers which is the thing I’m interested in. I mean, it’s interesting how others understand the same principal and how are they applying to this type of bikes however the XJ is not the best donor to being a Café Racer. Anyway I’m on the way to transform my old friend into a Café Racer. Well, not exactly. I’ve kept thinking about the bike a lot and finally I came to the conclusion she won’t be a Café Racer in the old meaning but she will be a Rat Racer. Why you might ask. And the answer is simple: if I want a Rat bike again then I have to wait another 25 years to own a bike which is an authentic Rat.

    Some of you might think that making a Rat bike is the worst thing what a man can do with these bikes but keep in mind: a Rat bike is always in mint condition mechanically but looks tatty from outside. So, here we are, in the middle of the process.

    First, the pictures how I’ve bought the bike. She was in a very sorry state. I’ve almost replaced everything because of the neglect of the previous owners. I think she had very hard times especially with the last owner. However she was cheap. I mean 250 GBP or 500 USD.

    Then, how she looks like at the moment.

    Well, you might think she is in a sorry state now but as I said, she will be a Rat Racer which means good mechanical state but tatty look. And this is what I’ve did till now. I think in my list there are some interesting answers to the questions what many of the guys are asking constantly. So, start with the rolling chasse then switch to the engine.

    - First of all, the brake discs were changed. They were outside their service limit so I’ve bought a pair of discs from ebay. I think they are coming from a 650 Turbo, but not sure.

    - Also, changed the brake lines to steel braided because the old ones were rubber and were as old as the bike itself. You know: safety first.

    - Then, I’ve just realized how bad state the rear wheel was. I mean, the brake shoes and the drum were pretty bad. At some point, the shoe just fall apart and I’ve found that the drum lining is cracked. So, I’ve bought another rear wheel from ebay as well as a set of shoes.

    - Right now, she is braking like hell :twisted:

    - I’ve replaced the wheel bearings, there were old along with the head bearings. The latter wasn’t an important thing to replace but it helped to reduce the deadly wobble around 70 miles per hour.

    - I’ve put progressive springs into the front forks which worked well but It took a while when finally I’ve found the proper setting for my bike.

    - But don’t go so ahead; let’s visit the control area of the bike. I’ve replaced the stock headlamp brackets with ones what I’m able to tighten on the sanctions. This gives me the possibility to lower the headlamp as well as the instrument panel as the biggest issue with the original look of these bikes if we’re talking about Café Racer.

    - I’ve replaced the stock handlebars with clip-ons which were from an Aprilia I think. I’ve tried various locations like, under the top triple yoke but the finest was at the top of the yoke. To be able to do this I had to raise the fork legs with about an inch and a half.

    - You might think it did ruin the handling but it’s not the case. It’s easy to write down but it took me many hours and miles to find out what’s the best setting for me and how can I make the bike so stable that I’m able to ride without my hands on the bars between 10 and 120 miles per hour. But about the lowering, yes it worked very well after the first try. The handling became more spontaneous and the bike transformed into a more playful one. To reach this, I’ve raised the fork legs as I said, filled the legs with 300 ccm of 10W40 motor oil (the Haynes manual talks about 230 ccm 10W30 but in that case the dumping wasn’t enough). The shocks at the rear aren’t the best but I gave almost full preload to them and with this setup the handling is fine and there isn’t any wobble trough the whole speed range. Just remember: at first I’ve got a bike which was fine in straight line up to 70 but at 70 she started to wobble so deadly I was scared to death constantly. Also, turning was another thing which was pretty scary.

    So that is the chasse right; now let’s talk about the engine. That’s an interesting part as well :twisted:

    - Just to be honest with you, I’ve spent weeks to tune the engine into this stage. What I’ve got? Individual pods with the velocity stacks installed as well. So, instead of to clamp the filter at the end of the carbs I’ve worked on the velocity stacks a bit to settle the pods at the end.

    - I had to replace both ignition coils because they became faulty pretty easily in rainy weather.

    - The carbs were cleaned many times and were rebuilt. When I’ve removed them from the bike most of the screws were stuck, I’ve found broken (literally) jets with many different sizes. So, a new set of carbs for different parts like the fuel bowl, a rebuild set and a Dynojet Stage 3 kit to make her tunable from the carb side.

    - Then, on ebay I’ve found a XJ900 engine for about 15 GBP which is about 30 US dollars. Cheap isn’t it? And the internals of that engine are just good. Unfortunately the clutch and the starter motor are missing but other than that everything is fine. The idea was to put the 900 engine into the chasse.

    - But plans are changing … instead of putting the 900 engine to replace the 750 (which is possible according to the sources I’ve found on this site) my plan was to use the 900 barrels, pistons and cylinder head and the 750 low end with the transmission and everything else. Then, I’ve changed my mind again and used the barrels and pistons only. So, she is about 830 ccm and because of the 750 head the geometric compression ratio is 10.1 : 1 instead of the stock 9.2.

    - Also, I had to replace the old MAC 4 into 1 exhaust system because. First it was leaking in many places, secondly the baffle was stripped off from the silencer and it was loud. Fortunately I’ve found a - bit rusty but other than this in good condition – exhaust system on ebay. It was about 30 GBP (60 USD). It went onto the engine without any problems. However it was loud a bit. Not as loud as the previous one but it was loud.

    - So, I had to repack the silencer again and … well. The baffle fell apart. So, I had to do some stupid thing: I’ve just drilled across the pipe then I’ve used a threaded rod and two nuts to secure the baffle … well. Doesn’t looks good but works very well.

    - Side note on this: the original silencer was way longer what you can find on the bike right now. It was the same length as the original but yesterday evening I’ve just picked up the hacksaw and … just for the sake of experiment :) The new silencer is on the way so I can ruin this one without any problems.

    - Also, I’ve installed an oil cooler from a 750. Unfortunately the oil cooler from the 900 engine was broken. I’ve installed that one as well but it leaked oil like hell. So switched back to the 750. It’s a bit small for this engine setup but it works well.

    - So, the engine … there are #45 pilots in the carbs and #132 mains. The needle is the first before topmost position and the diaphragm springs are stock. With this setup se produces something like 120 – 130 horses. It’s just a guess but I think it’s a pretty good one.

    - Unfortunately I had to do compromises with the jetting. I should able to use larger jet to have more top end but in this case there is no lower end because below 5000 RPM the mixture became so rich … the engine can’t run with all the four pistons igniting.

    - And there is the problem of the flat spot between 5 and 6 thou RPM. I’m able to remove the flat spot with a stronger diaphragm spring but in this case the lower end suffers too much.

    - So, right now I’ve got a pretty fat lower end which is more than enough in the city and I don’t need to spin the engine above 4000 RPM.

    - Between 5 and 6 thou she hesitates a bit. Just a bit, but it’s noticeable.

    - Then she starts to catapult me as a slingshot till 8000 when I have to change gear and the slingshot start’s to eject me again …

    - Just to let you imagine what I’m talking about: in third gear around 60 – 70 miles when I start to accelerate very hard and I hit a small bump on the road the engine spins the rear wheel for 10 - 15 meters.

    That’s where we are at the moment … and the things I’m planning for the near future:

    - New supertrap like exhaust is on the way. I hope it won’t ruin my jetting and I pray it would give more silencing. The one what I’ve got on the bike is not bloody loud but it’s loud enough for me to replace.

    - New seat unit which should be transform her into a proper café racer. I don’t want to cut the frame because of the overall stiffness but the new unit will end where the frame ends. Also, I’m planning to put a tail lamp from an old triumph. She will look mint ;)

    - I had to replace the speedo and the tacho as well because they don’t really mach with the look I’m after and the stiff suspension just killed both. They’re not showing anything other than the trip distances :)

    And I’ve got some plans for the far future as well.

    - I had to replace the clutch from a 900 engine. That one uses 6 springs and screws to hold everything together instead of five which is in the 750. At the moment she is pretty sensitive to the oil I’m using. She is able to spin the clutch so I had to put a bit of differential oil into the engine. It sounds insane but I’m talking about 200 ccm for the 2500 ccm of normal oil but it helps the transmission as well as prevents the clutch not to slip.

    - Also, I’ve found out that the front forks can’t really cope with this amount of power. When I hit the 90 mark the fork legs start to move not just up and down but back and forth in a pretty excessive way. So the plan is to install USD forks from newer machine which is more rigid.

    - This should mean new brakes as well but hopefully I would be able to keep these wheels.

    - Also, I’d like to replace the rear shocks because they are on their limit right now. The spring load is enough but the damping is not and many times the rear wheel can’t really follow the road.

    - Some cylinder head work to settle bigger valves; maybe some inlet channel work to be able to fit bigger carbs.

    Other than these … maybe I would reshape the petrol tank a bit but it’s just an idea. Maybe I won’t do anything with it. So that’s all folks, I hope you like she as well as I do :roll:

    My gosh, sounds like a ton of work, but sounds like you know what you're doing. I'd like to see some pictures though, they never showed up on your post. Keep posting, you got me interested, and I'd like to hear more, maybe next time with some happy snaps attached.

    Zsoltk- - You're really making a one of a kind! I hope you saved that 900 crank. 900 's are really 850 's , so your displacement is 795 CC now. I've read that 900 's had 98 HP stock, but you are running the 750 's head with less cam and valve area, but more compression.

    Did you balance your front tire? Stick the tire and axle between 2 chairs and see what happens!!! Get some lead.

    Yeah, keep us posted !

    Hi!
    I'm using the 750 crank with the 900 barrels and this how I've got the 830 ccm. About the cams and the valves. As I've checked the cams got the same profile as on the 750 and the valves are the same in diameter. Not sure about this one but next time I had to remove the head I will check :)

    Tire balancing. No, I didn't but the wobble happened because of the wrong setup of the forks and shocks. The solution for me was to have a bit stiffer rear than the front. It works well however on a bumpy road she breaks my bones. But I've coming from the road cycling scene where the bikes are more stiffer ;)

    Indeed! :D Unfortunatelly the stripes weren't my idea but it was brilliant but as you can see the duct tape is not working well, I have to find out something to prevent them from falling down from the bike.

    When you're done we should go for a ride. I may hold off on Russia next year and do Western Europe next August. My Eastern Europe trip has come to a conclusion and the maxim held up great. Today I am going to button her down for storage for the year.

    Hi Guys!
    The saga continues and looks like I slowly come to the end. Yesterday the guys fitted the new exhaust. They used the old down pipes then created a new collector box with a new pipe installed. The exhaust is slipped onto the new collector box. The sound became brilliant. It's not exactly silent. Well, if I'm just cruising the sound level is fine but when I'm accelerating hard is loud as hell. And I've heard at least five different sounds which is good. She's singing now :)

    And here is the picture:
    [​IMG]

    Looks good, sounds good and cost me about 160 bucks.

    Also, on the weekend I've bought a new instrument panel from an XJ 600 Diversion (Seca II in the US I think) and installed it without too much problems. The only problem is the tachometer. When it's plugged in it kills one of the ignition coils. I'm assuming these old wires aren't able to provide the necessary juice so I have to install some electrical circuits to give the juice for the tachometer. But other than that it's working fine. Cost me about $90. And the 2 hours of installing which is priceless:)

    The picture:
    [​IMG]

    So, here we are. The engine runs fine however I had to re-do the jetting and carburation. Also, I've renewed the connections between the wires in the ignition circuit but it didn't helped at all.

    So, three things are remaining and I'm done :)

    Blue face guages = YUM! I'd love to put some of those on my X but I'd need a matching temp guage.

    Nice work! The exhaust looks great.

    I like the look of your bike. Europe has a different slant on customizing.
    Survivor bikes are popular, the 70's B movie look. Ratbikezone has tons of pix. My XJ550 direction has changed again.lol

    Thanks guys! :)

    Gary, if you're changing the ideas every second day maybe you would end up building a car ;)

    The gauges are from an XJ 600 N - Diversion (that's the name in europe). You can find the picture on the bikez.com: [link]http://www.bikez.com/motorcycles/yamaha_xj_600_n_2002.php[/link]

    But I'm not sure about the exact model. I've found on a motojumble.

    Ha ha!! I haven't been been so enthusiastic about a project for 20 years.
    Every time I see a cool bike I want to alter my original plan to include the bits I like.It's gone from, selling for parts to ratbike to 60's chopper/bobber.

    Maybe try some metal bodywork tape? Still about the same color as the duct tape...but should contour to the tank better....

    Thanks for the idea! If I may, can you give me some links what's the thing you're talking about? It's hard to find the exact things in Hungary but there are equivalent things but with other names and brands.

    For example, I've just realized that you can use MuZ (well known and cheap European motorcycle which you can find in Europe everywhere) jets in the Hitachi and Keihin CVK carbs.

    That sounds cool! It's good to hear that you've became so enthusiastic after 20 years again. Welcome back in life! :!:

    The best thing with these bikes that you should be able to do a lot of different things. They are pretty straightforward and you can spend a lot of time in the shed to alter them and finally they will represent you. Which is fun and fun and fun :)

    You could try gaffer's tape as well. You can get any color you want and its pretty tough. Just do a google search.

    as for the dials, they're the same as what's on my bike. they're for the later xj600n diversion's (seca 2). I've got them on a 97 model and they're one of the coolest things on the bike. However, from the front it looks too much like a Suzuki Bandit so I've mounted a Puig Raptor screen to it which hugs the console & makes the bike look really mean :)

    Can we have some pictures? :) However, the bike is in the garage now and I didn't do anything with her for a while. I've bought an old car and the new thing is eating all my spare time. And it's a bit cold in Hungary at these days. Yes, winter is coming:) So, I'm using my Russian beast because she was designed to this weather :D

    On top of this? I tried some aluminium tape instead of the duckt tape and it's working fine. The only thing I missed was the proper placement of the stripes so I need to remove on of them later.

    It's cold and wet here. I'm going to assemble the engine this week and pick up my spoked 18" XS650 rear wheel and lengthen the swingarm. I'm designing a 2 carb intake. I'll post the results, good or bad. So far my free bike has cost me $900 in parts and machining. That used to be my bar tab when I drank!

    No Probs, I'll take some tomorrow morining for you. and get them on. I've also found that the screen takes the brunt of the wind even though it's only little.

    So, two months passed. I did a lot of work with the Russian beast but finally I've got a car which I'm trust in. After a bit of rest I was starting to feel a burning feeling ... nothing was done on the XJ. After a week or two of hesitation I started to work on the bike again. First of all, rebuilt the forks.
    Then checked the rear end for any bad movement. Luckily all the bearings are fine. Then ... well. Those were the most important things but I had to check the valve clearances. Yep, I'm still waiting for two shims and because of this I've got time to do all the things nicely and slowly.
    Next one ... those bloody carbs. I removed them, then started the disassembling but I didn't feel that burning feeling. I switched to the intake rubbers instead: I realized they don't line up with the channels in the cylinder head. That's interesting ... after a few hours of cutting and sanding all the intake rubbers are fine. Few other horses released.
    Then I started to think about the carbs as well. If you look into the venturi you will see sharp edges. Why not to sand them? Sharp edges are not the friends of the good airflow. Do it :) So, I sanded the carbs as well in hand with a total disassembly and good cleaning.
    In the mean time when I read the forums I realized that all my problems were in the wiring. I tried to solve those problems with carburation and things related to carbs but it didn't make real sense. Then when the light lit in my head all the puzzles formed a picture: wiring.
    Bloody hell, I was thinking about that for a while but I was trying to avoid this. I wasn't ready to mess with all the wires, connectors and everything else. But then I was in the situation when I can't do anything else and I'm pretty happy to rewire the whole bike. Three weeks ago I started with the brushes in the starter motor as well as in the generator. Then I removed the wiring harness and started to work on the instruments. Guys, that was the point when I realized why this bike didn't run properly: some circuit was drawing a few kOhm resistance instead of nothing. All my questions about the bad idle, dying at idle, hesitation below 2500 RPM, fading lights, no power over 7000 were answered.
    But because I'm waiting for those shims, I started to think about my oldest idea: a new petrol tank. A shiny well shaped new petrol tank.
    On that night I did a bit of research and I found I can make it although I do not have any tools for welding. But I can use rivets ... cooper rivets. Closed head cooper rivets on the polished aluminum tank. That would look good. I started to imagine the bike with a cafe racer style petrol tank made from aluminum and hold together with cooper rivets. Think about that ... it's better :)
    I bought two sheets of aluminum a bunch of wallboard sheets and I started to build up a new petrol tank. This is where I'm at the moment. When the base of the tank is ready I will upload some pictures.
    On top of this, yesterday evening I removed everything from the seat base to force myself to do something with the seat. Don't take me wrong, the original are just fine for the purpose but I'm using this bike for another purpose and on top of this they wouldn't match with the new look of the bike. Get rid of with them!

    Sure I love! This bike is all about good memories however I'm now owning her for long time. And some update. Finally I finished the wiring harness. I eliminated all the unnecessary connectors just 7 remained. Also, I removed a lot of wires and replaced a few. The harness looks way better and I don't need to force a lot of wires and connectors into the headlamp unit. At the evening I will take a few pictures.

    So, the pictures I promised after the finish of the wiring harness.
    First, the old one as it came out from the bike (I removed the cover of the harness)

    The unnecessary wires and connectors:

    And the new wiring harness at various locations:

    Also, there is a picture about a mock-up for the new seat unit.

    I was thinking about what to do with the rear end of the bike and various ideas came but all of them involved some sort of frame cut or an ugly result. But I do not want an ugly bike at the end (however some might think the original concept is ugly) and I don't want to make any changes which I can't change back. Why? Because the bike is pretty unusual. More precisely it's an XJ 750 model E which was manufactured for the Japanese market in 1982. I don't want to cut anything which is unusual or special.
    But finally I came to the result that the original seat pan defines a curve which really matches with the look of the bike as well as the curves of the early '80s.

    There you go! I am not sure why so many people are scared to do that with the wiring. Yamaha sure did put a lot of CRAP in the system.

    Hi guys!
    The story almost come to the end. At least I don't want to touch her for a while. I'm still working on the carbs - the very low end performance is not the best - but she's almost ready. Well ... she won't be ready but I decided to finish her for a while. Working on the new petrol tank is not a good idea in this weather. I mean, forming the wooden base involves so much dust that I want to do it outside and right now it's a bit cold. However for riding it's all right.

    So, first picture (sorry, it was taken at the evening when I finally finished all the important things)
    [​IMG]

    The seat unit:
    [​IMG]

    Just for recap, what I have done during this winter:
    * forks were rebuilt
    * carbs changed / cleaned / tuned
    * lot of different small tuning type things like polishing / sanding, etc.
    * new K&N pods at the end of the velocity stacks
    * muffler repacked (by the way, don't but this type of Higway Hawk muffler, it's crap)
    * exhaust painted to black
    * new wiring harness
    * new seat unit
    * electric flasher relay :)

    I'm going to take some more pictures on a sunny day to see where we are at the moment.

    Let me know if you can find another set of upper triple tree clamps and clip on handlebars like that in Hungary.... or just a whole front end!! I've never seen anything like that on a stock Yamaha in the states.

    Hi Crath,
    I was thinking that the front end is original on this bike. Unfortunately I wasn't able to find a proper description / picture about the 750 E model so I'm not sure about the origin of the front end. The clip on handlebars are coming from an aprilia I think, but I'm not sure. The seller wasn't able to tell me the origin.

    Hi Juan, thanks :)
    I can't tell you she performing better or worst because I never tried her without the velocity stacks. But according my tuning attempts on my other bikes she must run better with the velocity stacks than without them. I'm able to give her everything in fifth off idle and she pulls pretty hard till red line. If I'm not in real hurry I don't have to change to lower gears for overtaking.

    Sweet looking bike. Love the Rat Racer style. I have a similar thing going on with my bike. I know I'm kinda bringing this back from the dead, but I was wondering if you had any good shots of the velocity stacks/filter set-up you're running? I've been tossing around the idea for a while now.

    Thanks
