2012 Polaris Assault 800
Trial ported my jugs myself with the help of a local racer. Most companies out there that trail port the jugs, just clean up the surface on the middle, main port and then raise the outer ports to match the inner port. Thats it. $300-$400 to raise the small outer ports about 2 mm. I raised the ports slowly and gently from the exaust side until they were the same height as the middle. Then tappered the edge of the port on the inside of the jug so the rings would not catch the sharp edge. This was a slow and time consuming job, but you have to take your time to not ruin the Nicasil lining. It is possible for the average guy to port your own jugs, if you have the proper grinding tools. This is by no means a full blown race port, but the average trail rider does not need a full blown race port. I also ordered custom made base gaskets from Cometic to raise the ports, and then cut the stock head to match. RKtek head is going on ebay. Below is a picture of what I took off (dotted lines). The gray area is the stock porting to show you.
