yeah. im 220/230, going fast is a bitch but it will make you learn. what cylinder do you have? you may need to port match the intake. nothing hard or dangerous. no cylinder wall changing. just make the holes the same size. also check your timing. and yeah, that jet sounds small. but not if you have a small intake port, and are running a stock airbox. my e-50 was slow too. now it's fast, but it took 70cc.
