This aftermarket pilot jet kit is a handy item to have for fine tuning your new carb or after a modification to your bike that affected idle or low throttle fueling. It includes the following sizes: # 10, 12.5, 15, & 17.5.  These jets are for the following Mikuni performance carbs:

• Mikuni VM24 – 512
• Mikuni VM28 – 418

NOTE: If you don’t have one of the genuine Mikuni carbs listed above, please do not buy this jet kit as there are no returns or exchanges on jets.  These jets only work on genuine Mikuni carbs (they will not work on all the Chinese copies out there and none of the Chinese pitbikes come with a genuine Mikuni carb).
