Q: This makes no sense?
2 months 20 days ago
Why would anyone aside from a repair shop want 4 of the same pilot jet!? This should be a 4 pack of different sizes within the range of what the user thinks will work for his altitude, temp etc... The whole reason to re-jet your bike is to test various sizes to see which size runs the best. Dumb.

A: Depending on which model bike you have, individual jets in optional sizes can be found in our OEM section http://www.motosport.com/dirtbike/oem-parts
We also sell jet kits.
Many bikes that require these jets have four carburetors.

Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

A: The standard pilot for your 2009 Yamaha WR250F would be a 42 found in our OEM section here:

There is not a specific setting I could give you for jetting your bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.

A: Your 2016 Yamaha YZ450F is a fuel injected machine and does not have jets. However a fuel programmer would be recommended for optimum performance when installing a complete system. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.
