Stock jetting is either 230 or 240, but you're probably somewhere between 270 -310 with that pipe and no airbox lid.

So the way to tell is to simply look to see what size main jet you're running.

The correct jetting can be determined by doing a plug chop, which you should do immediately because you don't wan't to rely on what someone else told you.

Good luck!

The number size is stamped in the side of the jet.

Pull the carb, turn it upside down, pull the bowl to expose the jets...its simple

yes i already did that i just cant see any number on the main or know how to screw the main jet out

just use a small flathead screwdriver and take the jet out. it will be written on the jet real small.

You should be able to use a socket to break it loose. I think its a 8mm but don't hold me to that, its been a few months since I have done 1.

6mm 15 15 15 15

6mm use a little spanner, easy as pie!!!!

The number is stamped on the top of the main, you should see it without taking it out.
