I HAVE A 2005 WARRIOR WITH A PCIII AND THE CORRECT MAP.
THE BIKE RUNS GREAT BUT IT BACKFIRES AND SOMETIMES SHOOTS A BLUE
FLAME OUT THE EXHAUST. HOW DO I MAKE IT STOP?

First of all STOP SHOUTING. Have you removed the AIS [?] This is a system that injects air into the exhaust on over run to help burn any unburnt fuel for emmissions purposes. Do a search and you will find loads of info.

Welcome! Congrats on the 05! [^]

You may have the correct map, but your ECU Co numbers are leaner than what the map was made against. Factory settings are notoriously lean. You can do one of two things. Either richen the mix with the PC-III or bump up the ECU Co values 2-3 points for each cylinder. Here's a link for ECU adjustment. It's really very easy.

Congrats on the new bike, and welcome to the 4M.....

All caps = Shouting

Funny - I'd like mine to backfire more.

Backfiring is fun, with some measure. I know mine with the HK sideburners in the parking garage at work make some people jump. Its quit funny.

Roll your throttle forward,...this will help.

Welcome.

I assume your bike had the AIS removed already.

You can try the following: Save your current PCIII map before you make any changes.
Now increase the setting for 0% throttle from 750-4000 rpm by 10. Save the new map into the PCIII and go for a ride.

Should be a lot better. If its not enough go to 15+. Most of the time these cells are simply 0 after doing a custom map.

Hope this helps!
