BEFORE YOU ORDER — MEASURE YOUR JET FIRST
Remove the jet from your carb and physically measure it. If it does not dimensionally match this listing, this is not the correct jet — do not buy it.
Buyer is solely responsible for confirming the correct jet size before purchasing. Do not rely on year/make/model fitment guides — they cannot be guaranteed 100% accurate.
All jet sales are final. No returns or exchanges — no exceptions.
