64cc polini vibrates

So i have the good old 64cc polini, on my maxi but above 7000 rpm it starts to vibrate, is it the stock conrod, or my 3 shoe clutch, thing is unbearable at times, and tends to loosen every damn nut and bolt, along with my jaw, any ideas?

Check your bolts often lol

especially the ones that hold the engine to the frame ;)

yeah frame to engine bolts are tight, but it feels like engine is internally balanced.
