New which motoforce kit you running, the sport or the mid race ? if the mid race your belt might be slipping if it revs and u dont move. Up your contra spring and stiffen your clutch springs so your falling more into the powerband from the start. Ride it like you stole it, FAST...... Oh wait i am riding a speedfight -_- SF RIDER, Jun 8, 2013 Report#12LikeReply
unlike some dude. most of us on here know our way around a engine. we don't need mechanics for dummies books.
no idea if this is a troll/joke or whatever, but i have a full italjet morini engine in my back garden, £40 to you, bargain
