I installed a 1-1/4 on my viper about a week ago..only in the deep snow under hard throttle it almost sounds like its skipping the drive sprocket..but the track isn't loose at all..and I always thought yamaha's could run somewhat loose..maybe i need to run the new track tight for a few hundered miles?anyone have any idea on this??thanks

First season on my Viper(all protectors removed) with 1 1/4 Predator and ExpertX and have yet to have it skip on me. Im also running it somewhat tight cause I know its gunna stretch. Tighten er down it the only thing you can do to make it stop.

Ya, I'm thinking it may have stretched a bit. Tighten it up a bit and you should be good to go.
Put a 1 1/4 ripsaw on my srx 3 weeks ago. About a week in of riding and hit some deep snow while getting on the throttle and I heard it racheting. The track had stretched a good bit.

thats what i was thinking I was able to tighten up by fingers, but not sure if it was enough cause i didn't take the pipes off it was hard to get at. So what I did was tighten the track maybe a half turn because it was already tight, tightend the chain finger tight as best as possible and turned by transfer rods a bit stiffer and it hasn't done it yet, but I dont like running my transfer rods that tight..I mention transfer rods becasue i'm wondering if that some how would play a roll in it skipping if it was the drive sprocket and not the chain/gear assem. I guess i'll play around with it and see what i get...thanks for the help..has to be track tention or gear/sprocket right?

New tracks stretch, it's simply ratcheting because of this. I would go up a turn on each side, test it, and then go a half a turn each side until it stops. I always set mine up this way rather than using a scale. It may seem tight to you, but they have to be pretty damn tight without ani-ratchet drivers. Unless your tensioner on the chaincase came loose, I doubt that's the problem, but definitely check it.
It seems logical that hard pack/good traction would make it ratchet, but it is actually deep powder that puts the most load on it. Make sure you test it in deep powder. It may have been too loose since you put it on, they'll run fine on the trail and you don't notice until in deep powder.

Run Extrovert drivers (anti-ratchet) is my suggestion and probably gain some track speed as you will not be restricting the track as when running it tight.

your right, when i took it for the first ride down the trail it would ratchet when I stabbed it. So i took it home and tightened it up and it didn't do it, but once i got in the deep powder 2 feet or more she would skip pretty bad..the chain i put in was really tight too whe nI did the track change..the tention on the chain i was able to increase by finger..so i'm not sure if it was the chain and gear..did both at the same time lol...anyway I haven't tested it in the powder since cause I didn't want to break anything...but i'll give it a try and get back

Not sure of your definition of ratcheting "pretty bad", but if your getting more than about 3-5 out of it in powder I would start with two turns each side. Trying to help save you some time.
I've got a decent example for you. Last year my "helpful" cousin called me and asked what I was doing. I said nothing, why? He said, Oh I'm working on your sled for you and thought you might like to come see what I've done. My answer: YOUR WHAT?!? Anyway, he had gutted my air box and loosened my track cause it was "way too tight". He has anti-ratchet drivers on his, so his perception was a little off. Well, on the next ride my track was ratcheting in powder pretty bad. I tightened it up one turn and didn't get a ratchet out of it unless hitting a bank or drift in powder (mashing the throttle to stand the sled straight up). I was getting about 3-5 ratchets out of it, so I tightened it back up another turn (back to where it was to begin with). No ratchets since.
On a side note, I also put the guts back in my airbox and ended up routing my oiler cable too tight. It was being held open slightly. Took me a couple rides and fouled plugs (when running zero to quarter throttle) to figure out what was going on. I even pulled my carbs off to check them. Needless to say, he is NOT allowed to touch my sled unless asked to now, lol!
