I've got a 2002 wolverine that I've been building from the ground up. I bought it not running and knowing that a lot had to be fixed before I was able to get it running. That said, I've finally got it put together enough to where I can start it up and run it around the yard but right off the bat I can hear a noticeable clunk in the transmission. I'll run through the scenario, start up the motor and let it warm up and push in the choke and while it's still in neutral rev up the motor and just after reaching idle I can hear a clunk inside of the motor but it doesn't do it every time maybe 3 out of 5 times revving it up and letting it go back to idle. It does the same thing when in gear also. 1st gear (and all gears), give it a little throttal and let off and the bike slows down and just a little before the bike comes to a stop I can hear a clunk and fill the bike jerk slightly when I hear the clunk. Is this normal and I'm just being paranoid or is something going terribly wrong in the transmission?
