Thread: 2 stroke hot rodding

Tweet

I was lead to believe that the reed valves on a 2 stroke is where the magic happens.

Before you start porting, speak to someone who is familiar with this particular style of engine....you can really dork up the timing by porting randomly.... just like 2 stroke dirt bikes, you can kill the power by a bad port job. Find a reputable snow machine engine builder that knows Polaris...they can tell you better than us that have zero Polaris experience.

Two strokes are awful finiky animals. Many mods can actually kill power if not done right. Compression increases can screw up the scavenging, or lean it out and fry pistons. Like Robot sez, get hold of a 2 stroke wizard before you attack that sled.
