Jetting for air box mod.

[VenomMod]

I'm waiting for my Viper Forced Air Induction vents to put in my Venom. Right now it has plugs in place of where these vents would be on a Viper. How much do you think that i will have to adjust my jetting? I was thinking that at most I would have to probably go up one size on my main jets. Is there anything else i should probably look when I run these vents? I figured that they would come into play more less towards my topend.

It's hard to say exactly but i think you will definately be safe going up one jet size if you are running stock jetting right now. In all reality you would probably be able to run stock jetting with the forced air scoops installed because the stock jetting is plenty rich. Depends what temperatures you ride down to though.

I'm not running stock jetting. I have my sled jetted for the triple pipes that are on. I just figured that one size would be safe to start out with. I don't think I want to try running the ducts with what I've got in it. Probably will go up one on the mains to be safe for the test run.

I would guess that up one size would be more than safe even with pipes, The vents pressure the under hood area & that feeds the airbox mixed warmer air. Depending on how your wash & plugs look I would probably try your jetting as is....... If you have jetting room to play with.
