hello I recently had a mechanic tune and upgrade my bike but since I've had it back the low end has been terrible while the top end has been a great improvement (around 45mph from 35ish) I suspect this may be my clutch springs as it only lets out at 4.5-5k rpm it is a 2 stroke so it has a auto choke I was wondering if this could be the problem too as when I get the bike warm it bogs less but at traffic lights when I put on throttle it will just try rev high and spit smoke out the exhaust and struggle to move, I am also a big person weighing 100kg I was also wondering how people get the clutch bell and variator off without using a impact gun I have a very limited toolbox and everything I try doesn't work so any suggestions are welcomed setup: 70cc kit malossi delta clutch and bell (white spring) Malossi Multivar (8.5g rollers) stage 6 drive belt stage 6 intake 2 reed block 17.5mm carb #95 6mm main jet, #38 idle jet
Not easy without impact gun. Just do one thing at a time, fit 70cc kit to see how it runs, jet carb so it runs good, fitting all these parts all at the same time you don't know what's working ?
