I recently installed Boyesen Rad Valves on my 08 800 Summit. Do I need to mess with the jetting in order to obtain opitumum performance? I took it out and out and put 30 miles on it in 4' of powder and it seemed to run fine. I live in Alaska and ride between sea level and 2000 feet.
Any advise would be appriciated.
