Does anyone know if a 25/42 gears will fit in a prox with the stock 76 pitch chain? Where could I get the gearing chart from polaris?

I ran 25/42 last year after trying many other ratio's icluding 24/41 and 24/42.
You need to take a very small amount off the back of the tensioner and it fits with almost no chain slack and the most efficient chain bend possible and it is a great all around ratio for that sled, especially if you want decent top end.
Do yourself a favor and use the updated tensioner too while you're at it.
It is a phenolic material instead of steel. AMAZING decrease in that ignorant chaincase noise. It's also far easier to work with when removing the material from the tensioner bolt stop area...can do it with a hand file.
25/42 and the new style tensioner....all smiles!!
