I think i have run out of time and know how. About a month ago the bike started running poorly again and seemed to get noisier. I thought that this was simply a shim issue so i bought a shim kit re-shimmed to .05 clearances but it made no difference. I don't know where to go next? I have the MCCT adjusted properly per Bronco's method. I can only think that the rod bearing is going now or that the Primary Gear is coming loose again and causing balancer issues. It sure seems like the same sound that was coming from it just before the engine went the first time, (what many have described as piston slap but this happens at higher RPM's). The worst is when i'm running around 4500 to 5500 then snap the throttle, it floggs out and i can hear what sounds like the cam chain slapping around??? Maybe it's just an issue of gearing down, but it seemed that at one point this was not an issue. I did go to a 15 -44 gearing, so does anyone else expereince this with these ratios? I still don't understand why i am hearing all the rattling in the motor though and am worried that this is fair warning towards something going horribly wrong. I want to pull the clutch side cover and check the primary nut but i'm not even sure that i would know what to do if it was loose, it doesn't sound like just tightening it will fix an issues with the counter balancer? Maybe i should bring it into the stealership ----urgh i dread that. any thoughts are greatly appreciated and i will not be offended if you SCREAM IT!
