crf50 jetting

Recommended Posts

I just got a new exhaust for my stock crf 50, and i was wondering if i am going to have to jet the carb or not. And if i do where can i get the jets for it?

You probably will have to re-jet, especially if you add an aftermarket air filter. The XR50 stock main jet is a #58, and most guys are going to a #62. Any place that sells genuine Honda parts will be able to get you another jet.

Honda part numbers are:

99101-187-0600 #60 main

99101-187-0620 #62 main

For sure go with the #62 main. My 5 yr old son's XR50 has a UNI pod filter, Big Gun race pipe and the #62 main in the carb. The bike feels like the rag has been pulled out of the tail pipe. :cry:
