I installed a 144 track on my 2002 Mountain Max 700. It had a 141 on it. I added 1.7 inch rail extension because I thought I would need it. Right now I have my back idler wheels completely loose and my 144 track is extremely tight. This happened when I bolted the skid to the tunnel. It seems like I didn't even need the rail extension. Can suspension make your track really tight? Should I loosen my suspension? I think my front shock is all the way soft as it goes though. I know my skid bolts are in the right holes for the tunnel. The pitch drive is the same 2.52 and it has 2" lugs, just like my Yokohama. I can fit almost 2 fingers between my rail and track, but that is with the rear idler wheels in the loosest position possible. It should not be this tight.

Unless you swapped to extrovert drivers you will need to run at just about stock tension to keep from ratcheting. Proper way to check tension is to lay the sled on its side and pull on the clips in the middle between the rail curve and idlers. Proper tension is .79" of gap at 22lbs of pull. That track is also going to stretch, how much I don't know but you will have to take up on it after the first few rides. You are probably going to need to take up quite a bit by the sounds of it just to get in spec. With extrovers you can run 1" free hang, but even they require some tension.

I'm fairly new to sleds. But I'm wondering how bad the 141 may have been stretched. Was it the original track?

The track will stretch. I'd say just tighten your adjusters up and go for it. Then re-check everything in 50 or so miles.
there is only about 1.25 inch difference in length along the rail between a 141 and a 144 - remember that the track length is lugs * pitch and indicates the circumference around the track (have to divide by 2 for linear length)
