I was thinking of putting on a 14 or 15 tooth front sprocket and a new rear one but don't know the size for the rear.

 

if ur gunna put a diff rear sprocket on to go with a 38 if u want alotta top end or do a 40 40 will give u good top end without takin away to much acceleration

 

what kind of 400 is it if 400ex just get a z400 they r really nice

 

I'm on a low budget a 400ex or a z400 is not in the budget. I wish thou, the kids I ride with there parents buy all there toys. I buy my own my parents don't pay for a single penny of it. And I haven't even got to the best part yet I have to have my own job to pay for it because my allowance is 4.00 A WEEK THAT SUCKS!!!
