running them loose in the powder lets your front end lift up out of the snow,then tighten them up for trail running,but too loose in the powder and you will start to ratchet unless your running extro's,thats the one thing i didnt like about my m-10,i had to keep my limit strap very tight to prevent ratcheting..
This is just my opnion, I think a loose limiter strap causes a steep aproche angle making it hard to get the sled to stop trenching and get on top. However less coupling definitly gets the skis out more. You hear so much talk about rolled chaincases on the mountain sleds now it's hard to ignore aproche angle.
permafrost..is this the first time with a 1 3/4 track?if you think you went good with the 1.25 wait until you try the new one,i had a 1.5 on my 670 and couldnt believe the difference from going from 1.25 to 1.5,come mid jan ill be putting a 1 3/4 on my sled for when the snow is deep
Panteraone, I rode my buddies 99 summit 600 136"x 1.75" a few times in the powder and on the trails. It is way different from the 1.25". Let go of the throttle and your kissing the windshield .CrazyB ordered a 1,75" for his new gade too. I can't wait to test it out next year, Im sure i'll still be getting stuck the odd time though
The standard track with the group I ride with is a 156x2, we ride nothing but powder and mountains. I believe that if you let the limiter strap out, it decreases the approach angle. It also gives more transfer to the track, which can cause trenching if suspension is not set up properly. I have never had limiter strap adjustment cause ratcheting, that is normally due to track tension, which we run at the loosest possible setting to avoid friction which steals power to the track.
yes its true not all suspensions are the same,with my m-10 i had to run the track so tight and also shorten the strap or it would ratchet in the deep stuff,it had a terrible AOA,raising the limiter helped as it raised the tip of the rails and gave a slightly better angle then with the strap longer,but then steering was very heavy,i would have had to go 144 and do a pullback to make the m-10 work for me,id rather just get the expert-x.
