Anyone have the Big gun exhaust/ K/n filter and know where to start on jetting. the dynojet jet kit only has up to a 170 main jet but the bike still is running lean. But thats a good thing. When its right it'll be awesome. Just wasnt wanting to buy 25 different jets at $3 each maybe someone can tell me where to start. I know it will depend on my altitude etc. but you may be able to get me somewhere close. I'm guessing like maybe a 200main or 250 range????? I also cut the snorkel back to the square part and used a larger diameter rubber hose for an extension. It really allowed more air to engine but I'll have to get jetting right. Thanks guys

 

i put the big gun on my 04 sp600 with a k@n filter, i got by with a 160 MAIN JET.
