****If your jet does not measure like ours do not buy it because it will not work****

All jet sales are final.  
Our year, make model fitment guides can assist but are not 100% accurate due to numerous reasons. We have no control over jets once they leave us; some customers drill them out, test and tune etc.  See also additional things to check before ordering. If needing help send us a picture of the jets removed from the carb and also read identify that jet

Please take a moment right now to measure the jet prior to ordering.
