hi guys my bros 250r really doesnt have any bottem end i mean its good but if your up a hill and happen to let off the gas you cantjust punch it to take off you have to slipp really bad and even then sometimes you just lose all the power..
ichanged the sprocets to lower it.. it has a pipe and jetted carb i am not sure about the crank yet but i got to the piston and i dont no what size it is i thought about a higher compresson piston might help but frist i need to no what i have in it.

thanks a million.
