Specs At A Glance

Good To Know

Q: Do I need to rejet this carburetor after installing it? A: The unit ships jetted for the stock 500 HO engine, so no rejetting is needed unless you have added a performance exhaust or air filter. In that case a small main jet adjustment may be required.

Q: Should I check my fuel lines and tank before installing? A: Yes, old fuel lines and a dirty tank can send debris straight into a new carburetor and cause the same running issues. Flush the tank and replace the lines while the carburetor is off.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
