I never replaced bearings when I got the bike, just the crank seals. So worst case scenario it could be a bearing.
I'm hoping for just something clanking like the chain or flywheel. It seriously is after I just barely let off the throttle once the bike is warm. Only happens at a random mid throttle position not at idle or WOT.
I have a guy in my town that has helped me out with timing and misc things. He still thinks it is pre-detonation. He wants to retard the timing even further to see if he can get it to run cooler and not knock.
I do have a small air leak where the sha meets the intake. Waiting on a o-ring and new shim in the mail. I also ordered some 60 range jets just incase I need to upjet futher.
Fingers crossed I figure it out and it will be something easy. Probably not though..... haha
Thanks Don for all the help! I will let you know what I find out.
