atm i have got an 05 aerox wid standard de resrcited pipe. it will do 50 but it struggles to get there. however i know thats the rollers. is there any way of getting it to do more than 50 without changing bore or pipes?
when the variator is derestricted, was the thin washer taken out as well as the spacer? if not, take the thin washer and puyt it on before the nut, this will add a tiny bit morespeed, then go for some light rollers, 4gor somthing
stiffer clutch springs so you use more revvs when pulling away, allowing the pipe to use the power more. try some 4g rollers aswell then
