vibrating at take off!

[Smellybumlove]

yep as it says, since i increased the power i have noticed that it vibrates ALOT at full throttle from a standstill, it feels as if the belt is slipping?.

i have no idea what it is, checked the belt and it looks fine, all the variators and clutch are almost brand new and top quality aftermarket stuff, i cant figure out what it is.
one scooter guy here in taiwan told me its normal for a high powered small scooter, but that doesnt sound right to me.

any ideas?

Something's slipping for sure, but that could be normal. The Dr Pulley HIT clutch would eliminate at least one part that could be slipping. That would still leave your variator and belt though. Hmmmmmm decisions decisions
