stock front sproket is a 14 i dont know the rear 38 im guessing well anyways the lower on the front you go the quicker its gunna rap out, accelerate and the more its gunna spin its tires,the higher you go on the back it will also accel faster and spin more tires , now if u go higher up front you loose accel and ull go faster top end as well as the lower the rear the faster u'll go top speed but you cant just switch sprokets sometimes you need to get a new chain because they dont fit correctly on or a half link etc
