    Word.... instead of a hose clamp, Kawi has a skinny spring clamp thing to hold pressure on the intake duct from airbox to inlet side of carb body. #11 in the parts fiche

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

    How did you recognize that the rubber dampeners were worn so badly in the clutch basket on you KZ rebuild?

    and do you suggest changing over to electronic Dyna ignition or just replacing point and condensers??

    thanks for all the knowledge chuck

    It rattled like a coffe can full of bolts at idle and ALMOST went away at speed. I thought clutch hub bolt or basket. Took all that apart and didnt see anything wrong so i figured it was the primary chain. Anyway, when i got to rebuilding the top end for new valve stem seals and valve lapping i cracked the cases and replaced the primary chain because i had read about them stretching and making a lot of noise. This led me to discover there was a lot of slop between the two halves of the secondary shaft. So it got the new rubbers and the primary chain. Took a bit of patience but i found a NOS chain off ebay.


    edit.... rubbers didnt look worn away at all. I think they shrink and get hard thus letting them get loose and rattle.

    ok

    Thats relieving. Actually

    a lot of good detective work on your part. Damn. I suspect they might shrink and harden if the crankcase is without oil for years?? Do you think That might have been the case

    It sat out behind a barn in the Texas sun so long the red faded off the bike. The first thread I linked shows that result. It had oil as I recall but that doesn't negate your theory.
