Common questions
What's the significance of the #135 jet size?
The #135 indicates the orifice diameter, controlling fuel flow. Compared to smaller jets, it provides a richer fuel mixture, often needed for modified engines or at lower altitudes.
Will these jets improve my V-twin's horsepower?
Proper jetting ensures your engine receives the correct fuel mixture, which maximizes efficiency and can unlock the full potential of your existing modifications, contributing to optimal power output. It's a tuning tool, not a standalone power adder.
Are these jets suitable for all Mikuni carburetors?
These are large round main jets designed for specific Mikuni carburetor models. Always verify your particular carburetor's requirements and existing jet style to ensure compatibility before ordering.
