Frequently Asked Questions
The #15 refers to the calibrated bleed hole size in the pilot jet, which controls air bleed into the pilot circuit for leaner tuning at idle/low RPM.
No, this is specifically for Mikuni VM/BS series carbs. Check your carb model first.
Smaller number (smaller bleed hole) = richer pilot circuit; larger number = leaner.
Often yes, for complete tuning. Match with main jets and needle position based on your setup.
