What did you do to your Yamaha today?

got the left side piston out and it was all gummed up. Probably why it was not working. Everything changed just need to bleed the brakes now. Do that in the morning then going riding before it hits 100 degrees. Maybe the coast at least it will be cooler there.

 

I've noticed a lot of tech questions popping up in this thread lately.
Please keep posts in this thread related to what you did.
Post questions about what to do, or how to do something, in the appropriate forum area (preferably in the thread about your machine).

Thank you,
Management.

 

I just went through this for the first time and, once I figured out a few tricks, it wasn't too bad at all.

• First, set a baseline. I dry set my floats all the same using a small float ruler (this assumes you have matching floats, valves and seats). It doesn't really matter what you set them too, so long as they all match.
• Second, accurately get a fuel level. Once mounted in the rack, I connected the tubing and held it straight up (otherwise, I'd get a slug of air in there that messed things up). I'd loosen the plug and then slowly lower the tube down and around to the side. This method kept fluid from flowing back into the bowl and eliminated the air pocket. I took my measurement, shut off the gas, and drained all 4 bowls.
• Third, dry-set the floats against the wet measurement. If my wet measurement was off by 2 mm, I'd adjust each float 2 mm. Though not 100% accurate (because the float is hinged), this got me closer faster, since I didn't have to keep draining & measuring.
• Fourth, fine tuning. Re-do step 2 for each carb, one at a time. You'll start off very close. When you adjust, use your ruler as a guide to make sure you don't adjust too much in the other direction.

For me, the big issues the first time I tried it was the air in the line and the annoying, messy, and endless fill-measure-drain-adjust cycle.

 

1. This is really the wrong thread for that discussion.

2. Bending the float tang by 2mm to get 2mm of change in fuel height is the incorrect procedure. The tang just needs tiny bumps to make big changes in float height.

Now that I've broken my own rule (#2 does not belong in this thread), I'll keep to my own warning and delete any posts I make that don't abide by the purpose of this thread.

So everyone, what did you DO to your Yamaha today?

I didn't even get to look at mine; had to rebuild a 3-blade mower deck and put a new carb on a string trimmer.

 

Moved it from the shop to its parking spot in the shed for everyday riding.

 

Pushed my 82 650 Maxim out of the garage and made room for the girlfriends new-to-her 81 650 Maxim that I so graciously rode home for her. (After I bought it for her of course...late birthday present) Now the work begins! But hey, at least there's 2 xj's in the stable

 

Went for an evening ride about 20-30 miles round trip just to see the outlaying area and it was beautiful to get out of the city. Outside temp was 70 degrees very nice gonna take the wife tomorrow evening over the same route.

 

Gonna change my oil tonight after all the misc. float work I just did... and take a ride in the morning...

 

It was suggested in somebody else's thread about misfiring that the cause might be a failing fuelcock. My xj700n is having a similar problem that I thought might be related to the gas I am using because the misfiring appears to improve or worsen when I fill up. Usually when I fill up I am setting the fuelcock from reserve to on and the fuelcock also has an occasional drip. I tried the advice given which was to set the petcock to prime to remove the vacuum from the equation. This appears to have made a significant reduction in the misfiring although I may suffering from confirmation bias. I will order a rebuild kit from Len in any case.

It is uncanny how much knowledge there is on this site. I had read a post earlier predicting that the petcock would likely be the next thing to fail.

 

Swapped flasher module to account for LED signals, removed self cancelling module (which never worked in the first place). Discovered while doing this that my petcock leaks, but not till after it managed to cover my carbs in gas. Good times.

Then discovered my new "electronic" flasher module was not in fact electronic and would only work with at least one stock bulb. Put the original flasher back, got to return this and just order what I need from Amazon.

In the mean time, I guess I'll just utilize the manual flash method, or BMW method when there's less traffic.

On the other hand, the days ride in to work was fantastic, nice and sunny, lots of other riders out, and the XJ ran beautifully.

 

I betrayed her memory by buying a Honda and parking it in her spot.

 

*Cries*


(Pics or it didn't happen!)

 

The horror!

Actually Honda, Kaws, Suzuki's etc. better than nothing.
Pics?

 

Rebels are great little bikes too.

What year?

 

It's a 2008, 7800 miles. Yes miles, it's formerly an American bike. When I take pics, I'll start thread in "Other Motorcycles".

 

Does the '82 XJ650 have a factory self cancelling module for the signals? Mine seems to and it doesn't work at all, either does nothing or just completely randomly turns the signal off

 

Dunno about the 650, but my 750 does. Hasn't worked since I got the bike, though - like yours it usually does nothing but occasionally turns the right hand blinker off after 1-2 blinks (which is very annoying).


... While I had a great time into work, my ride home didn't work out so well. Because I'm clever like a fox rock, I wore my tinted visor in... Get off work at 11pm. It's pitch black out, not even moonlight, due to the torrential rain.

Choose between peering through (wet) sunglasses at night, or raindrops in your eyes.

I think I'm just going to return today for a refund.

 

Like!

I'm on a similar schedule. I use a clear visor and wear sunglasses underneath. But only when it's bright out. I ain't that Lux!

 

I would agree riding a bike any bike is better then nothing!
heck I even give props to those on scooters. Cause they are freak-in craziest of all riders.

 

My nemesis for the last ride of the season is this guy in his late 70's rides a scooter.
