UNITED MOTORS XPEED-50R

Instructions for ordering: check jet dimensions. If the jet in the carb does not dimensionally measure like ours, then it is not correct. Do not buy it! It will not work. Try here: identify that jet.

Our year, make, and model fitment guides list jets for popular factory and aftermarket carbs, but due to numerous reasons there is not a way to make them 100% accurate. Therefore, do not rely on the fitment guides.  See also additional things to check before ordering.If you need help send us a picture of the jets removed from the carb. identify that jet can help as well. 
Please take a moment right now to measure the jet prior to ordering. Taking a bit of time now will help avoid issues later.

We have no control over jets once they leave us. Some people drill them out, test and tune, etc. To protect everyone from getting used and abused jets, jet sales are final. No exchanges or returns.

Help us help you! Please measure the jets before ordering and email with any questions. It is easier to check now then potentially have jets arrive that do not match!

*** All jet sales are final. No returns or exchanges.****
