Does anyone have experience with big singles in small alloy frames?

Then there are theorys about putting sand in the frame etc etc... but those are just rumors i have heard.

dry sand is a awesome vibration/noise damping tool....I doubt they are just rumours... shake an empty jar....then fill it full of sand and shake it!! beat ya its harder to shake

you are lucky that you no longer have the twin balancer shaft assembly. I had a klr600 recently which had shat the balancer shaft drive chain. The rear balancer chain I think also drives the oil pump, so the engine was a mess.

By the way I tried to find an aftermarket counter balancer drive chain to suit but could not find one anywhere. I ended up buying the original part from kawasaki for just over $400. yes, 400 bucks for a length of roller chain.

Maybe thats why mine has been removed....
Wouldn't be surprised!
