here we go please help aerox 70cc pm 70cc ally barrel and head pm reed block pm boost bottle technices pipe 3.5 grm rollers pm belt pm gear up kit its on standard carb i have got a 21 mm to go on but not got around to putting it on what it is is it is a dog to get it going off the line since i put the gear up kit on it and is only pulling around 65 mph ,b4 the gear up kit it was not to bad ,it just not rev when you are doing 65 mph it sounds like its only reving at around 6 ,000rpm it feels like it wants to go please help i am thinking 2.1grm roolers and a strong spring on rear pully and stronger clutch springs is this the right way to go or can you tell me other ways thanks ian
i dont think the pipe is anygood.. but shouldnt cause that problem :/ has it only just started happening? you have the carb heater connected? and 2.1 is extremely light... i had 2.5 in my rox, with malossi's stiffest torque spring but revs to much..
