im running a dr d slip on exhaust with airbox lid off and the instructions say i need a 178 jet. any ideas an where i can get this? and do i need a different needle?
go to your yamaha dealer jets are usually in stock
needle will probably have to be ordered 4 bucks /pce for jet $ 18 for needle
order the needle for the yz450f
search !!!!
