What is the general consensus on track porting? I just got done drilling 270 holes in my 1 3/4" x 136" track and it seems to clean out the snow from the rear suspension quite well. Originally I thought it would weaken the track too much, but the Crazy Mtn. Extreme guys are doing it to their new $24,000 sleds so I figured they must have tested it extensively and everything came out OK.
My pattern ended up being a 1 1/2" hole in the center of the track and two 7/8" holes on each side of the 1 1/2" (5 holes across between each set of lugs). Originally I wanted to do 1 1/4" all the way across, but I couldn't find my 1 1/4" hole saw! I figured 1 1/2" all the way across would be too much.
I guess theory is it takes out some of the "rotating mass" so the engine doesn't have to work as hard to spin the track as well as sheds some snow weight from the rear suspension.
Any other +/-'s to look for/think about??
