Hey guys, I just bought a 04 raptor and i got a GYT-R air filter and HMF slip-on included. What should I jet the carbs at with these two things included?? Thanks

If you are keeping the air box lid on, you may want to start with a 145 in the left carb and a 150 in the right. If you are going to remove the lid, you may want to try a 150 and a 155. Always do a spark plug check to verify. Check this out: http://67.15.38.161/forums/showthread.php?t=32 . Hope this helps.

Thanks....that post helped. It's also still new so I should probably wait until its broken in. But ill try the plug test out anyways. Thanks again.
