Hey guys new member, first post, I have been trying to research my problem and have see similar but not the same issues.

I just bought this 2005 Yamaha Bruin 350 2wd, and it has been rode hard and put up muddy. I bought it from my uncle who couldn’t get it to run. I replaced the carb and battery runs great in neutral, belt comes up in the groove when revving, but when you put it in gear it takes off at idle, almost like the weights are stuck out. If you hold the brake, it will kill the engine almost like letting out of a clutch on a manual with no gas. If you put it in gear and give it some gas it runs and rides great. But when you stop it dies. I don’t think the idle is too high although I could be wrong. Any suggestions before I tear in to the clutch?
