I have a mbk Mach g 50cc ac. All stock just derestricted I replace the rollers to 5.8g and now can't get over 35 pmh before I could do about 42 mph but I don't know the gram of the ones that where in it before ????
Hi When you say 'de-restricted' - what do you mean ? Ring out of the variator or actual exhaust mods? Is the scooter struggling to rev or is it screaming like a chainsaw but not going anywhere ?
All been de restricted the variator and the exhaust has no restrictions. It revs fine but at 35 its screaming
