leak jet question

Recommended Posts

have a 2012 450x and just did the slide, main jet and needle upgrade. i was givin the directions from one of the tech's on how to do the competition mods. it says for 2005 crf450x. it recomends changing the leak jet from a #70 to a #65. but my bike has a #60 in it from the factory and they ordered me a #55 leak jet. should i use the #55 or wait and get the #65 like the paper says. not sure if the 05 paper work is out dated.

Not too much difference between 65, 60, and 55. I'd have a tough time telling by the seat of my pants.:lol:
