Experimental clutch, version 2.0 Last year, I made the version 1.0 experimental clutch mod, using adjustable features that I felt was not suitable for others to implement. After determining the settings and measurements, I made the parts for the version 2.0 earlier this year. Now that I've...

I've got a 1983 with an electronic Boyer ignition, Hugh's PMA, and stock Bikuni bs34 carbs. I recently had a leakdown done and i've got 4% on the left, and 12% on the right. So, I know I won't be able to get her running perfectly, but I feel like I can still dial it in better than it is now. It...

I have a tx650 engine that has good compression but is missing the points covers and the majority of the points components, it has the compression release on it which from what I have read makes it a 73 if im not mistaken, I also have a front end minus the top clamp I have a set of mag wheels...

I have approached a motocycle mechanic about fixing my first gear woes (with all intention of doing it myself). My 78 Japanese import XS was working fine, I made a few changes, removed tach drive, paint and little bits. 3 weeks after doing all this my bike lunges in first, it's like the gear...

Ok, found a couple threads with some information, but not really what I'm looking for. What happens if you put the KB springs in with stock retainers and shims? I understand it's not recommended by KB, but what actually happens inside the engine? do these things wiggle around and fall out of...

I have been working on this top end rebuild for months (making time for it has been hard), but I'm nearly there. Before I rivet the cam chain together, I want to know if this is a normal amount of air leakage (you can hear the hissing of air as I turn the crank): I am turning the crank with a...

I'd like to do this mod to my bike, but no time and not handy enough to mod the rockers. Could send you my rockers or have an eBay set delivered. will pay money or something. PM me, lemme know terms. Thanks! Ern

I'm looking for Yamaha XS650 complete running engine include carbs, electrical kits and stator.

I have my engine all torn apart and I plan on soda blasting and painting parts of it and I have a few questions about the topic. I plan to paint everything black but the cylinder jugs. If I soda blast the jugs and do not paint them, should I hit them with some sort of clear coat to keep them...

Need to send my engine and frame number to yamaha to get dating records so i can register my xs2. Anyone know where I can find the engine number?

Been restoring a 1980 XS650. Have been cleaning the engine and trying to paint the case and heads. When cleaning the lower front case, a small piece of the metal chipped off and reveals what seems to be some type of pin below it (as best I can describe it). Not sure what it is, if it needs to be...

Hey everybody, Im working on rebuilding a 1973 tx650 engine and it seems most of the stuff I find says tx or xs and others are tx/xs. Im wondering what exactly is cross compatible. Mainly talking about engine seals and gaskets. but would be good to know about pistons and rings. they seems to be...

Good evening follows. I have my 650 on the bench with the top end fully assembled and adjusted and I just noticed something that I overlooked. With the plugs Out, it takes far more effort to rotate the engine than I expected. It seems obvious that since I can rock it a degree back and forth...

My bike is in great shape but it won't start due to a my ignition box getting some moisture in it. I'm looking for the Type TID12-03, it's the only thing that will work for the 82. Thanks!

Cold motor, nothing removed or propped open. Nothing added (like squirting oil in the top) but a test plug to keep from frying things. Electric start to turn it over. Left side, Right side, That's almost a thirty % difference? And these readings are quite a bit different than the readings 6...

Looking for complete engine include carbs and all electrical kits. Turn over motor, have a high compression, and not frozen motor. Will buy more than 3 engine if you have.

I'm looking for Yamaha XS650 Complete engine with Carbs, Coils, Regulator, Charging System, Points Ignition. Turn over freely, have high compress, not frozen. Will buy more than 3 engine if you have.

I have looked through the Tech sections and I don't see a reference to this. I have the frame stripped with only the engine left to remove. Carbs are off, top mount removed. I would like to lay it down, disconnect the mounts and then pick up the frame minus the engine. Some questions: 1. Left...
