Polaris RZR

Had a chance to tune this ATV the other day. All it had was a snorkel system and a furl controller.
The RZR came in sputtering and misfiring at idle and low rpms. Adjusted the fueling on it and was able to get some clean revs and made some decent power on the rollers.
Ended up with 39whp and I was told that at the crank these ATV from the factory sport 42hp.
So not a bad little gain.
Here are some pictures from the day and I also have some video that will be uploading to my youtube page.
