Posted September 21, 200915 yr Hi Guys! History of bike.. Ok basically, I bought my aerox a few months back with a de-restriction and it hit around 45 mph, i then decided to put a new £120 sports exaust on it and changed the rollers, for about a month it ran smoothly,with the exaust the bike could now hit 60-65 mph. Problem now.. Basically it accelerates to 20mph, slowly hits around 35-40mph and after about 10 mins (only if the wind is behind me or downhill) i manage to hit 42mph, if it manages to hit this it will go straight around to 60-65mph if not it will run at around 40ish until i need to stop, I have taken it to a garage and he has fiddled with the petrol to oil ratio and cleaned the carb etc.. but cant find the problem... So my question is anyone had simular problems or know what it is this would be massivly appreciated if you knew. Extra info.. -It accelrates really fast from about 5-15 -The drive belt is fine -Only got 3k on the clock - When it manage to get to the 42, it suddenly rapidily accelerates straight round and will continue to acceleate as long as im going above 42. PLEASE guys i really need answers my local mechanic is baffled and i need this to run fine!! Thankkkks alot.
October 1, 200915 yr you have the wrong rollers for the speed you want. you need to get heavier ones to get top speed. light rollers = acceleration heavy rollers = top speed. you need to get different rollers or an exaust gasket with a smaller hole. you will need to change the clutch springs if your using anything otherthan your stock rollers.
October 1, 200915 yr Did you re jet the carb when you fitted the sports exhaust? Also, have you changed the variator? I hear a polini one is best, as it gives the best gearing for top speed & acceleration?

October 5, 200915 yr have you tried a higher heat range plug? especially if it's running o.k when it cools abit.
