Crankcase Porting?

[Mark's RMK]

I won a crankcase for a 2002 800 Polaris on E-Bay. I did not realize that the case had some porting until after the auction was done. (seller posted additional information on the weekend and I was out of town)

Do I need to worry about this case being suitable to use with stock cylinders? Is it the full race porting that has crankcase work?

I have had SLP trail port some cylinders but they did not require the case for that work.

Any info. to help ease my anxiety would be appreciated.

No you do not have to worry even if it is full race port! BUT IF YOU HAVE THE CYL PORTED TO MATCH YOU WILL HAVE A runner. to gain the best out of the case porting it is good to have the Cylinders matched to the case? BUT YOU CAN HAVE STOCK CYL ON PORTED CASE AND IT WILL WORK! you will flow more air in the case so started with more fuel when jetting too.
