Jetting products are NOT returnable-these are tuning parts therefore no returns or exchanges. Go elsewhere to buy jets if wanting to return them. There are too many variables to ensure the jets listed below will fit the carb. Pull the jets from the carb and measure them first. If incorrect jets are ordered it will be unpleasant when they arrive, just delay the tuning process, waste time, be frustrating, still wont have the correct jet and will end up measuring in the end. We have advised to measure, if advice is ignored the frustration is your fault, don't blindly purchase jets like a novice. MEASURE YOUR JETS, cant figure it out see our FAQ extreme top left of page and read "identify that jet" link. things to check before ordering.
