Please Note that the stage descriptions and related jet kits are correct for the majority of motorcycles and might need adjusted due to high altitude riding or other factors.
Q: Are the jet Kits for all carburetors or for one Carburetor?
A: You only need 1 Je Kit for your Motorcycle. If your motorcycle has two carburetors, you will receive two sets, if your motorcycle has 4 carburetor, you will receive 4 sets.
Q: What are the needle shims for?
A: Needle shims are used to raise the needle to allow for increased fuel delivery mainly during mid range RPM's. This is a cheaper but effective alternative to so called tapered needles. 2 needle shims are comparable to 1 clip position on the expensive needles. In combination with a better Pilot Jet, shimmed needles are highly effective.
Q: Why do you include Pilot Jets?
A: We are the only supplier of carburetor jet Kits providing Pilot Jets in our Jet Kits. The Pilot Jets are very effective in decreasing deceleration popping, improving cold start and low RPM performance. Combined with needle shims and better Main Jets, a total RPM range improvement is established.
