Frequently Asked Questions
The number refers to the jet orifice diameter in hundredths of a millimeter. A 52.5 jet has a 0.525mm opening. Larger numbers = richer fuel mixture, smaller numbers = leaner mixture.
Signs you need rejetting: engine runs too lean (hesitation, popping on decel) or too rich (black spark plug, poor fuel economy). Altitude changes, air filter upgrades, and exhaust modifications often require rejetting.
No. This jet is specifically for FVM11 and FVM22 series carburetors. Using the wrong jet type can cause poor performance or damage. Always verify carburetor model compatibility.
Typically no. Most main jets can be accessed and changed with the carburetor mounted on the engine, though removal makes the job easier and cleaner.
Round jets are the standard Mikuni design. Some carburetors use needle jets or other configurations. Round jets are simple, reliable, and easy to replace.
