I bought the track already ported. I agree, I am not sure porting that much is worth it. I think they were 1 1/4 inch holes. The track is 5-6 years old and I got my money worth out of it. The hyfax was there until the tip of the rail stabbed the track and destroyed the track and the rail on that side. The hyfax is in pieces, some on the mountain and some in my garage. It was a beast to ride back to the road where the truck could get to me. It stuck 4 more times in the 1 mile to the road (lucky I was close at the time it happened). The good thing is that I have another sled to finish out the season and can fix this one over the summer. The bad part is I hate to put a sled away for the year this early. I have no intentions of fixing this sled this year, just thought you guys would like to see my destroyed track.
