I have a 02 500 HO, I was thinking of putting the (moose) dyno jet stage 1 kit in the carb to get a bit more out of it. Has any one used one of these kits and is the power and performance as stated by manufacturer :slomo:

Are you changing to a full exhaust system or just re-jetting in hopes of better performance. I don't think you would see any performance gains with out the full exhaust system. You might get a little better throttle response at best, with just the re-jetting, might. But Dyno Jet is a great product. Used it on one of my motorcycles about 12 years ago.

I've installed at least 100 dynojet kits. I'd say 80% work as advertised on a stock motor. Most of them have been on motorcycles though. And most of them with at least pipes and a high flow air filter.

Exhaust opened up

I opened up the exhaust a couple years ago and now I put a Uni filter on it
