can I put a upgear kit on a standard 50cc zip sp as it seems to be screaming over 45mph compared to my friends stock zip aircooled model
pedparts did a blog about the gear ups on them lumps..something along the lines of it can be done but although the kits have the same tooth count,their actually slightly smaller in diameter and fit but are noisy cos they don't mesh fully..have a shoofty on there and if yours is the PROPER box..no probs..
Some say yes some say no to gear-ups on standard peds. The only thing i can say is go for one that will give between 10 and 15% difference above standard. Any more than that and the engine may struggle. But as with any gearup, you will lose initial acceleration so you will have to play with the roller weights to get it right again.
