2008 WR450 main air jet. GTYR or stock.

3 posts in this topic

Hey all I just bought a 2008 WR450 and im trying to figure out the jetting that was installed in it. The guy before me installed a GTYR AIS removal kit along w all of the jets. The one jet that Im having trouble figuring out is the Main Air Jet. The attached pic shows my carb with what looks like a jet that is about 1 inch down in the carb. I have heard that the stock Main Air Jet isn't a jet at all and just a hole. I've tried to take it out but Its really tight and I didn't want to break it off inside. Does this look like stock or not?

Thanks!

Don't know if what you have there is stock but if it is the GYT-R part leave it in.
