As the 2013 season winds down, I wanted to drop you a note of thanks and mention how satisfied my riding buddy Mike and I are with the 670 dual ring piston rebuild we implemented on our 500ss engines along with your billet heads.
Our 500ss engines have never sounded or performed better ...it was a little extra work, shimming the cyls/deck height, but at this point I'm very pleased with the results. We started slow, way on the fat side ... our mpg is currently what I would call safe @ 13-14ish, but now near the end of the snow season in Maine, both sleds run awesome!
I thought that I would send you a quick message thanking you for the great sales advice and product when I purchased my new Wossner produced pistons for my ’13 Polaris Switchback 800cc last fall. We had a short 6 week season here in Eastern Ontario, Canada but I enjoyed every mile (3200) on the new pistons. What a difference in performance over the OEM pistons. I followed your break-in advice and adding extra 2 smoke oil to the 91+ fuel on fill ups, plus following your warm up procedure instructions. This has been the best investment that i have made for my sled and cannot wait for ‘15-‘16 snowmobile season.
I purchased and installed one of your drop in kits for the Polaris 800 dragon. I know you haven’t done testing on the 2009 Dragon but I’ve been testing it and have found it to be very rewarding. The cooling is at least 15 to 20 degrees cooler than it used to run and I needed to install one step hotter plug. The throttle response is amazing. It develops power way sooner than before and holds torque all the way through to top shift at about 8150 or 8200 RPM. I am thrilled with the performance and couldn’t be happier with your product. A friend of mine who owns a 2013 Pro rode on it and couldn’t believe it “Spanked” his sled. He liked the way it pulls hard all the way from about 6000 RPM or so. I am recommending your product to all my 800 Polaris rider friends.
