I've got an '09 outty 500, HMF pipe(sounds great), Dalton clutch springs and custom snorkeled. fantastic atv. Problem is that there is a nasty backfire/popping sound comming from the air box and it is lacking power, what could be the cause? is it a possible exhaust leak?

Chances are you're running lean. You have to richen up your A/F ratio. I have an HMF on the way, and HMF told me that I may or may not need an EFI controller, so I am going to run mine without it first, and see how it runs. But if it backfires like yours, I am going to get a Power Commander 3 as most people on these forums swear by them. I also have just installed a snorkel kit, and it runs fine with just the snorkel kit on it.
A couple of people on these forums told me that these bikes run rich from the factory (well, the 800's atleast) so I shouldn't have a problem. I hope not.

Thanks for the reply. The pipe sounds great!!!!. the quad was starting to pop before the pipe, quess I should have mentioned that. I put new fuel in and new plugs. is it a warranty thing to have them check the air/fuel mixure, or is it something else?
