What did you do to your Yamaha today?

Wow! What a stunning machine!

 

Thanks @Brhatweed I’ve had 36 years to modify things. Thinking it might be time for a new paint job though. When I look at the sidecars at Advrider I am completely humbled, especially the suspension systems built.

 

Took my carbs out for the 5th time cleaned them cleaned fuel lines. Just trying to get her to run nice again… I’m thinking it could be a carb sync that’s needed but I’m unsure. Thousands of dollars put into my xj700 and I’d love to just appreciate it fully

 

Carb sync can make a HUGE difference. If you were closer, I'd lend you my Carbtune Pro. AND ColorTune. I know they're expensive upfront, but I'm so glad I made the purchases years ago. Good luck.

I keep forgetting to post - rode to a nice coffee meetup on Saturday and the co-owner of the coffee LOVES the '80s I-4s and talked to me for a good half hour about my bike.
Then Wednesday, my kid and I rode to the local car meet and there happened to be quite a few bikes there this time. A guy I remember from last year was at least a couple beers in and told me about his '81 Seca. He even still had pics on his phone even though he sold it in '91. Funny thing is he got it at the same dealership mine's from.

Continue to have a crunchy starter when the engine's hot and also a hanging oil light. I did do an oil change last week and didn't see anything concerning in the oil. Right now, I'm just riding it to meetups and doing the daily on my WR250R until I can dig into it this winter (hopefully out-of-sight-out-of-mind doesn't get me again).

 

So, the last week I replaced the throttle shaft seals and other rubber bits, also a thorough cleaning . Then color tune and YICS balance a couple of times. Running great now. very smooth throttle response and plenty of power when getting on the highway. Passing is smooth and fast, very quick from 100 to 140Km/h with room for more, but then I realized how fast i was going in a 100 zone. Also, today new Dunlop D404 tires. Last week I noticed that my tires were 13 years old so took care of that before getting back on it today. These new ones really grip on the curves.
Amazing how quick these bikes are for a machine that's over 40 yrs old.

 

Rolled past 42,000 miles on the way home from work (and looking at another motorcycle - shhh, don't tell her).

 

Added some cheap replacement signals to my SECA. Not the most elegant but they work and they're not busted and taped on.

 

After 5 months of nothing but problems and headaches, I finally got my 86 maxim x700xs running like a top. Valve adjustments, carburetor cleaning, complete rewire, any many more things have been done to this bike and I have this forum to thank for that. My grandpa built choppers for fun before he passed away, so I feel I need to keep the family tradtion alive. I was a total mechanic noob before, and this bike has taught me so much. Thanks to all who have helped me get this thing going. I'll see you on the road

 

Finally got around to the steering head bearings. It was a big job for me because arthritis forced me to do it in stages over a couple of days. But it's done, thanks to the abundance of info from this group. Brand new roller race bearings- what an amazing difference. There were a lot of divots in the old races and it was grabbing in a few spots. Very smooth now and better control in the tight curves.
That was the last thing left to do on this bike because it runs great, it's reliable and a blast to ride. The way it sits now, it should last another 40 years! I suppose I'll have to leave it to someone in my will, like owning a parrot or turtle.

 

Still trying to get my 750 RH running with rebuilt carbs. Later plan on going to get a vacuum pump at the local auto parts store (loaner tool) to finish (hopefully) bleeding the front brakes after the rebuild.

 

Don't be discouraged if it takes a long time to bleed them. A vacuum bleeder helps, but isn't the only tool needed.

If you need help with carb setup, we have that too.

 

The portable power vacuum pump still isn't allowing me as get any pressure. Got the brake handle pressing on the handle while bleeding them. Trying all the bleeder screws including ,the anti dive . Haven't rebuilt the anti dive system as of yet.

 

Relax the handle completely while using the vacuum bleeder, piston in the bore of the master that's beyond the return port won't allow fluid to pass from the tank down assuming the little hole is clear.

On my end I passed the 49,000 mile point on my SECA 750

 

Today, I added to my Yamaha collection. Up to 5 two-wheeled contraptions now.

1981 XJ750 Seca
1997 YZ80
2007 Vino 125
2008 WR250R
And now *drumroll* . . .
2015 FJR1300ES

I LOVE it. The silly thing only has a little more than 2k miles on it. I've already changed the oil and final drive. Will get to brake and clutch fluid this weekend.

Congrats on your new rocket ship. I bet your license is cringing in your wallet realizing how often it is going to be coming out to talk to the officer....

 

nice!

 

I've yet to have one of those talks on a bike *knocks wood* Guess I'm overdue. On the commute in to work, I was using the cruise control primarily to keep from creeping up faster and faster. It's like butter at 80 (allegedly), and pretty darn quiet, so I'm going to have to re-calibrate after being on the screaming/naked Seca. I did one takeoff from a light in Sport mode (been keeping it on Touring) and might have peed a little.

A few pics attached:

 

For one weekend, I didn't need to do anything to the Seca, but the WR205R got fresh oil, and the FJR got fresh brake and clutch fluid. The brakes were flushed a few years ago, but the clutch fluid was neglected/original 2015 and looked like Hershey's syrup. Luckily the reservoir cleaned up well (didn't get an 'after' pic, though). Might be in my head, but the clutch response feels more precise off the line.

I also organized my garage a bit to get the bikes together. The YZ80 is still on the other side of the garage, though.

 

I learned that our XJ's have 2 different oil level sensors. While researching the sensors here I ran across a thread where 1 of our learned members had posted that the Atari wearing XJ's use 1 a sensor that is read by the computer all the time, the non-Atari wearing XJ's use 1 that is simply a switch. I discovered I needed to know this because my 750J is wearing the wrong one. Examining the 5 sensors I have revealed the Atari sensors have a red wire the non-Atari sensors have a white wire. I am hoping @chacal will chime in shortly and confirm this, or tell us I am not as smart as I think I am. So, I am in the process of changing out the sensors.

 

Ones is normally open and the other normally closed. The atari requires the OIL line to go LOW as it's biased with a 5V reference which in turn triggers the logic to flash the OIL message and blink the WARNING light when it goes HIGH or open while the others need to close the switch in order to complete the circuit for the OIL light.
The way you can tell is by flipping the sender upside down to simulate a full oil pan and check its state with an ohmmeter, closed will be the atari sender provided the magnet is still good. They use a reed switch with a magnet on a float that over time gets weak and doesn't always pull the contacts together.

 

Today I rode my Seca for the first time in a week after riding the FJR every day since getting it. For the first minute, the ergos, especially the handlebars, felt weird. It was loud, smelly, slow, clunky, and archaic compared to the FJR. And it felt like home and I still love it.

Some kids in a brand new Tesla wanted me to race them. I knew better. They asked if I could wheelie. I demurred.

 

Most nice days during the spring, summer, and fall in Ohio, I alternate riding my FJR and my Seca to work. You're right about the obvious differences between the two.
I still really like my FJR after owning it for nine years, but the Seca -- which I've had for 24 years -- is easier to flick around. I find myself smiling more on the Seca, and concentrating more and working harder riding the FJR. (I'm sure it's related to my skill level.)
When I park the FJR, I'll get off, pat the seat and say, "good work."
When I park the Seca, I'll get off, pat the seat with a smile and say, "good girl."

 

Today I replaced the mc on my 82 xj650 and will bleed in morning. I have a new clutch perch and gas cap arriving tomorrow as well. Excited to get this installed, I do not want to burn out my clutch more than I have.
I all of a sudden have a bad wobble after dropping the bike and hitting a bump that same day. Someone told me to loosen the lower pinch bolts on forks and really bounce it up and down and then retighten to torque. Has anyone of this before? I can do all the engine maintenance, but I don't do forks and such.

I am in Sw Washington state if anyone is close by.

 

That was sound advice on the pinch bolts.
Something anyone who’s riding a bike should do unless you know for certain you tightened them or Yamaha did.
Hitting a bump while slightly out of position can wobble any bike. Was it just an occurrence or is it repeatable?

 

Well, the answer from Brhatweed is correct....but yes, the sending unit for the computer-monitoring dashes has a red lead wire, and all of the others have a white wire.....kinda clever that Yamaha thought to make that distinction for ID purposes (because otherwise they look the same).
