Prime the lower legs before you put them on the bike. Cleaner that way.

Bought & installed Louis silencers...I'm very satisfied. Very nice sound, not too silent, not too loud :)

Hi guys..having some issues with the carbs here. Last week I got new floats and adjusted the fuel level to 5mm below carb body. Then I adjusted pilot screws to the factory specification (1 and a half turns out), synchronized the carbs and tuned idling again. But it seems that the engine isn't idling very smooth at all. If I screw the right carb pilot screw all the way in, the engine starts to stumble and die. But if the left screw is screwed all the way in, there is no difference in rpm at all.. I've checked the ignition timing, it is set correct..there is also major difference in spark plugs color..the carbs have been cleaned and rebuilt, air cleaner is K&N in the original airbox..when I take it for a ride the engine works good. Please help.. :S

Have you adjusted the valves yet? If not I'd start there.

Have you checked compression?

Timing might need to be adjusted. The timing marks are only a suggestion. Especially if your compression is low AND gas is nothing like it was 40 years ago.

Hi guys. Solved the problem with the carbs (leaking float...).
But now I have a different problem with the engine. Last time I went for a ride it worked perfectly. But few days ago I've noticed a major problem...as I pop into 1st (or any other gear) and release the clutch lever, the bike won't move at all... first I suspected that there is something wrong with the clutch. Then I removed clutch plates and it seems that there is a problem somewhere else. If I turn the rear wheel with my hand, the inner part (clutch center) doesn't move. I'm not much of a mechanic, but I assume that if I turn the wheel something should move, right?

Take a look at the engine sprocket to ensure it has not come loose. It is the sprocket at the forward part of the drive chain. If it is not secured properly it can cause the symptoms you described. Ed

That's exactly what happened, thank you 650ed! It looks like the thread on the shaft was damaged and some wise guy tried to fix it with teflon tape....I will try to turn a new nut that will fit the lightly damaged thread...
