I'VE TRIED THICKER BASE GASKETS ON 583 AND 617 MOTORS AND DID NOT SEE ANY DIFFERENCE ON THE DYNO. I PUT A .050" GASKET ON A 670 AND DID. THE 583 AND 617 HAVE A SINGLE EXHAUST PORT AND THE 670 IS A TRIPLE EXHAUST PORT. ANY THEORIES ?

Ski doo engine revs drop at 55 mph

SKI-DOO

I ride a 2001 ski doo touring 500fan, and over the past year have spent a lot of time fixing issues with it (it was sitting unprotected in a backyard for 5 years). I cleaned the carbs, fixed some electrical contact issues, and redid much of the fuel system. It used to bog down when I went past...
