Thanks Momma and Aggresivezebra ....I feel the T3 is the is the leader ....as you said there's a good Polaris dealership 10 mins from my house. It's so nice just running 15 minutes for my kids sled for parts. It maybe the only reason the polaris is in the run.
just a guess but i heard about this problem with other cats- theres a goofy throttle sensor under the flipper , if the flipper is loose the senser will retard the engine.
