I'm gonna rebuild my buds 85 200X topend. It's down to 60psi compression and won't start well. So, no use just rebuilding it to stock settings. I want to cam it, valve springs and the topend is noisy as crap and must need a camchain and tensioners, both sprockets and I believe he bent a valve sinking it last week. Honda 200 motors are loud period but I hope changing the cam chain and it's parts will help.

SO.... You guys have the 85 model, not me. What did you do and buy? I want to give him a 10.5:1 piston, bore it to clean it up, a nice cam to run on super unleaded gas, valve springs and I'm concerned about the chain/sprockets and guides. I believe Honda is discontinued. Vesrah valves work, do the have a chain and sprocket and guide kit or who does? I've only seen the DID chain for sale for the cam drive. Gotta do valve seals but I hope the guides are good. I think only Honda has those?

Anybody offer a whole kit??

Ideas? Prices? Products?

THANKS :)
