Pulled the clutch, put a dial indicator on crank and it was good. Started sled without clutch. Reved it up to 5000rpm. Vibration still there. Motor didnt seem to run wierd, rev faster, over speed, idle down slower, or blow up. Guess ill ride it as is till next summer or till she blows. Whichever comes first
Help. Bad Vibration

She'd be riding all winter... And summer... Come to think about it I'd never see her again. Hmmmm... This could be a good thing
phil... did you do a compression test on the sled?
What about checking piston wash on the domes?

Havent checked compression or wash. I put new rktek pistons in this summer. Sled runs awesome just vibrates

I'm guessing you answered your own question rate there.I PUT NEW RKTEK PISTON'S IN.Start there.
My 13 puts my right hand to sleep. Right bar shakes really bad.
Spend the money to have Indy Dan long rod your crank and you will notice no more vibration and gain a fair amount of performance to boot. This is a result of two things; better rod ratio and an increase in crankcase volume.

Sled ran fine after pistons. The shaking is new. Last three rides. Boost-it motor mounts 2 rides. Probably 10 on pistons.
Motor is going to indydan next summer for long rod.
2600 miles on sled so far
Have you had any detonation? If so it may well have flattened the needles of the wrist pin bearings and left dents in the upper rod bearing surface. Someone else on here just ran into that issue.
