try adjusting the screw mix first, you can always add the jet later at the recommended size (45/180- most likely). watch your plugs to see how its burning, and let performance be your guide.

I have the Vance and Hines straightshots and the Sceamin Eagle air intake.I used 180/45.I tried 175 but it was better with the 180.Also the air fuel mixture screw needs adjusting.It is under the plug that has to be drilled out.The whole job is pretty easy as long as you follow the instructions on this site.

If I can get away with not jetting and just adjusting the mixture I will... if not, I guess I have to go buy some jets. I was looking online, and they are $3 each, but then shipping kills it. I guess I have to find a dealer that will sell me a few jets to try out.
