The bike is a heavily modded xj 650 maxim. I don't normally use gauges and rife more with a feel foe the road and the bike. While I was riding i...
carbs have been completely rebuilt. I also have new intake boots and gaskets. new throttle shaft seals. Its now somewhat harder to start and its...
Yeah seals are out. Live and learn. Just thought I would try to help the next guy.
Hello, My 81 xj 650 maxim is currently down. I have another post on that matter here:...
Thanks, and yes I throw the vac gauges on it every time. No colortune though.
Engine sync? Is that the same as the carb sync or are you referring to timing? I think with my low compression readings I think I didn't add...
pics are of worst boot.
I am getting a set of new boots. I am getting new throttle shaft seals as well. I checked clearances again today and all are within spec. It very...
#2 plug now
Ok Here is the update. went out and compression tested all cylinders again. The first time I did this I had JUST put oil in. Within like minutes...
can that be done without dismantling the engine? I am unfamilar with this process?
Agreed on the lean plug clue. I have backed that out to enrichen considerably more than the other 3. I have seen a change in plug color but still...
I put the jets back in that I had been running with no problem for over a year. Before I did i put them in the carb cleaner gallon and let them...
yes for sure. I have had this bike running for a couple of years and I have a spare parts bike. Both have the 4H7 markings on them and I switched...
This where my fuel levels are currently
I will try brake cleaner. The intake manifolds are in ok shape. Some of them have some cracks but none that I have seen all the way through. I...
Man I just dont know. This thing is driving me crazy. Now it's acting like it has throttle shaft seals going out. Roll on the throttle and...
I would consider that. Thanks! Des Moines to Dubuque is a good ride on a hardtailed 650 but hey I just tuned it up right!
I didnt get everything put back together. I got a 4-1 exhaust and I took off the exhaust to change the oil filter. When I removed the exhaust I...
I have been guilty of this myself and last night after a little more tinkering I found that my diaphragm on the creased section was still not...
I will update it. I do think that I may have had a diaphragm not seated properly. There was one that had a little bit of a crease in it and I got...
Ok disassmbled the carbs again and drained oil. The oil smelled like gas.put new oil in checked compression. everything was low but then I read...
Not this time. I did about three weeks ago when I tried to switch out #42 pilots for #41 pilots. I didn't like the way it sounded, so I went back...
1981 XJ 650 Maxim The other day I was riding and noticed that the bike had started sputtering upon acceleration. The bike has pods (I know) and...
Everything is working now. After all your thoughts I dug a lil deeper. There was another relay tucked away in the wiring loom. All taped up and...
all turn signals are aftermarket.
OK That is helpful. I will look into that. I know I can hear current enter the relay when the key is turned to on.One little click is what I hear....
I have everything working properly now except the turn signals.I cannot get that figured out. I have tried 2 relays, 2 different handlebar...
Not yet but that is great information. I haven't been back out to work on it, however, I do have some pics of the diode block. I am sure that the...
OK back again for advice. The bike is a heavily modified 81 xj650 maxim. I have a Clymer manual and a complete spare parts bike. I have access to...
the photobucket extension tool does fix the missing images at least it did for me on chrome.
OK the bike is reassembled. Mucho improvement. I have full throttle response through first gear and probably 20% more power. I did have a little...
I had a shim that was marked .270 and was really .266 . I had a 265 installed and then switched it out for the 270. Since the 270 was really 266 I...
They were removed. The screws are fairly worn like they have been turned quite a few times. Not stripped yet but definitely worn. So knowing that...
Ok, all valve clearances are in spec. It does make sense to use a micrometer to measure the thickness of the shims. I had multiple shims that...
I dont know how I could help, but I do work for a larger web design company in Iowa. Not sure if anyone wanted me to look into anything but I...
Is that a fee I would pay or the website provider?
On most of the pics in this forum I am seeing a Photobucket 3rd party image instead of the actual photos. Anyone else?
I have the tool coming tomorrow I think thanks to Chacal. I have made significant progress using 2 wires inserted next to each other to hold the...
Yep it is working much better. I am still not finished. I have 3 of the 4 intake shims in spec. I also have 2 of the 4 exhaust side shims in spec....
Well, I am getting there. I started the throttle shaft seals tonight. They were in terrible shape. I did pick up a telescoping magnet which helped...
Went back out and got it loose unable to get it pulled out just kept popping back in. Loosing the bolts that hold the cam down just a little on...
I do have the lobe t=rotated to give me the most space as well.
Ok tell me there is an easier way to get these damn shims out. I am working too long to get them out. there is next to zero clearance I cannot...
Ok one more thing. I just got finished reading the thread valve clearances exhaust side. I had not read that before and wished I had. One thing...
I also am having Chacal send a couple very thin shims to use a baseline for clearance measurements. Man I dont know what I would do without this forum
Interesting. I see how that could work
