If 3 gram rollers were about right, try 3.5 gram-ish...
Did it gain any top speed with 3 gram rollers or just revved like nuts and moved slowly?

And Polini Evo probably wants some ignition retarding.
EDIT: Or as said below it may need advancing.

Check out my member profile, and then RoxxTV on you tube. Also search my previous posts, and the replies i received. They will get you going in the right direction. Your setup is almost just like mine, barring the Yasuni.

My EVO likes ignition ADVANCE, but thats my Evo
 
is the belt sitting on the very edge of the torque driver ?? sounds a little like the bike taking off in the wrong gear meaning the belt is not at the very edge?????
