I just recently bought a kq 700 it is fully snorkeled and has 27 inch itp 589's. I have been reading up on the king quad for the for the past month and i noticed that almost everyone says their top speed on a stock kq is around 70 my kq only makes it to 50-55 tops and doesnt seem very responsive. i just checked the belt and it seems fine too. what could be wrong with it? thank you.
