I don't want to screw the thing up!(jetting)

Recommended Posts

Okay, I'm thinking of pulling backfire screen and doing the airbox mod. The thing I'm afraid of is screwing the jetting up and having PIA problem with a bike that runs great.

Will these mods effect jetting?

The Airbox mod MAY require a larger main jet. I run a 178 here in the Cali high desert. Stock is a 170. 2000-4000' at about 45-65 degrees temp. I highly recommend this mod!!!!!

When i pulled the filter screen out of my '04 here in Denver I had to go up on the main jet 1 size from where most people here in Denver run them. So stock is 165. I run a 162 w/ the screen pulled out. The stock bikes in this altitude generally need a 160 to run correctly and most dealerships will install a 158 or even a a 155 which is too lean.

Does that help?

Where do you ride usually?

I told you to bring that thing over here and we'll get everything jetted, adjusted, and set up for you!

I ran a 160 main even with the screen out, and it seemed to run fine, especially at Rampart.
