Hi everyone I'm new to the forum and a 2000 te 610 that I just bought, and have a question or more. The guy I bought it off said it runs but needs a new counter balance shaft so I did some reading up and found some tell tail signs. 1 top engine mount has one bolt missing and one bit slack and you can see where it has been moving. 2 clutch basket nut was slack and the main springs in the bottom of basket have been moving as the rivet washers are worn (can they be replaced). I've turned the nut just to the top right side of clutch will I have put any thing out of timing. The bike has supermoto wheels on now and shows 17km on clock but not sure if true. Any help and info much appreciated.
Loose top engine mount bolts are common and a major vibration problem. If the clutch hub nut and basket rivets are loose, someone was doing work on your bike that was over their pay grade. Google up Indy's 610 Clutch Spring Washers, 610 clutch hub bushing and also Husky 610 timing chain. There is also a good forum for the 2000 era 610s on the Adventure Rider Forum.
if its still vibrating a lot after fixing the engine mount bolts it is likely the woodruff key. Lots of info on it. I am 905 sure it is a number 9 key. You don't want to be doing to much riding with it until you check they key is still in place.
