i recently bought a 85' 350x and it has a DG pipe on it and i believe it has no baffels or packing in it i was wondering what the stock main jet was in this bike, the jet in it now is a 138 and i know i usually change the jets on my other bikes when i put a performance pipe on them. i have read that people go up to a 150-155 main jet, should i?![]()
