hi,i have a '87 ninja1000 need to know what size main jets to use with seperate K&N filters with aftermarket exhaust.......i already have the needles with different settings...on the second from top right now....with one washer.
Thats a blind question. No one knows what other varables are in your set-up. If you have an aftermarket jet for that bike its probably a Dyna Jet stage what ever. Call are email them and ask your question.
What you need to do is call 18008690497 PST and tell them you
need part number k09-3.0 these guys took all the guess work out of
jetting. Just let them know any other mods to the bike, pipe, cams
etc.. They will supply you with a kit that gets very close to what you
If it just the main jet size, you might be able to squeeze that
out of them but they will ask you if the needles you have, have 5 or 6
grooves in them. If you are have a drivability issue I would really
suggest to buy there kit.
thanks for the replys
i think my needles have 5 groves.......bought it with a kit installed.....but don't think the main jets are right.....but dont know.....don't want to have to buy a whole kit.
