jeepwm69 5,560 Posted June 11 Is it not running right? I’m redoing the riser in a few minutes on my 06 500. It would start cutting out if I gave it more than half throttle, and I figured out that 1.5 inch was starving it for air. I’m running 2 inch from the airbox all the way to the end of the snorkel now. The only 1.5 inch I’m leaving in place is the pipe that actually goes through the wall of the airbox. Share this post Link to post Share on other sites
Fishfiles 13,647 Posted June 12 I have 2 inch fittings going thru the air box walls on both my 450s. I can say I never tried running it with 1 1/2. So I can’t say if 1 1/2 is ok or not. But I have heard it said so many times that you need 2 inch pipe with a 450. to answer your question “ are you jetted properly “. You do it by checking your plug condition against a plug chart lol And if the person riding behind you is complaining their eyes are burning from unburned gas might be a sign of over fueling Share this post Link to post Share on other sites
