hi i have a 50cc speedfight 2 and i am looking to buy newrollers as my current standard rollers are ruined, i dont know what weight rollers to get though can anyone help??
if your looking for top speed then get heavier rollers but slower acceleration or lighter rollers result in faster acceleration but slower top speed. You should meet in the middle and get 9.3grams. I have the same and get 60mph
