03 Factory Mod cylinder question

[Cowbell]

Anybody know if the cylinders on the factory mods the same as a stock 800?

 

[Cowbell]

I think they are ported but not sure. Need to get one and was wondering how I go about doing this so it's matched to the other side.

Well, it would depend. If you ordered Ski-doo's factory mod kit, it would just be standard cylinders, high compression head, twin pipes, race carbs, and of course the reflashed race curve in the MPEM computer.
Some of the X-racers can send their engine over to Trygstad for porting and fine tuning, so those would be different.
You should be able to tell if it has been ported. If the exhaust is ground out it will be smooth and large. Other ports cleaned up and expanded.
