450 miles now, riding in NY sucks I should have 3 times that by now. When I first got the sled I noticed the track was every tight but figured it would stretch NOT. This is the first sled I had that the track didn't stretch. The hi-fax are shot so all I wanted was another 60 to 80 miles for them to last. So I loosened the track in hopes of saving the hi fax for a last ride. I like to run the track loose anyway I was to the line in the bend on the hi-fax. THAT DID THE TRICK as far as the ride goes it helped a lot the sled no longer rides like a wood truck. Its not perfect but its 50% better than it was. I have 285psi in the rear sock and I weigh 290 in street cloths. Now into the dealer for a oil change and have DuPont hi-fax put on. I have also noticed that the sled is not revving to 10,500 RPM I have to take care of that also. I like the sled to rev to 10,700 and settle out to 10,500 RPM when all said and done. I don't why loosing the track made in ride better but that is all I did and was amazed in the difference again not prefect but a big difference and it worth a try for others!!!
