I was out yesterday and I had rode about 35 miles in temps about minus 10. I stopped and waited for about a minute . When i tried to go again I had to give it some , like throttle to the handle bars to get it to move . I have just had it serviced with new drive bearings and hyfax. Later it seems it kinda misses at a constant speed . Is it just cold or is it something else , any ideas ? Let me know
 
Sounds like your sliders(hyfax) are sticking,were you bt ant chance riding on hard icy/crusty snow?I would almost bet that's your problem.I've heard it from some older guys around here that have sledded all their life that you need to "season" any new sliders by heating them and cooling them about 6 or 8 times to get the plastic to harden up.Do this by running on glare ice or hard pack for a stretch and then cool them off in deep snow,or water if you have access to it.
 
yea , I think your right . It was fine today when I went out . However, Im still picking up a real bad vibration thru the tunnel, handle bars , seems like its in the drive line . Its a real distraction. Kinda frustrating . I would have thought new bearings on the shaft would have fixed that.
 
Did you check all the bearings in the skid?That may be where your vibration is coming from or you may have a piece of ice lodged somewhere in the skid.I know mine has a tendency to build up between the top idlers on the rear shaft and the tunnel.
 
it proberly melted spots on the slids check the slides i bet they have indents in the slides from the track clips melting it happened to me once i had to pry the track of the rails then it was rough ended up replcing slides and keeping track loose till the got broke in
 
If it is your hyfax having flat spots from over heating, add ice scratchers to your skid and or skis, then never a problem in low snow conditions.

PS:

I have seen tracks welded to hyfax in ice or very packed trail conditions. We have had to get out propane gas torches and pry bars to break loose. The longer your track in the bigger your lugs, the bigger the risk of cooking your hyfax.

Sounds like your track was too tight after putting new hyfax in for sure. I always run my track as loose as possible until the hyfax wear in a little bit.
 
Well , the vibration is getting worse , sounds like a low droin noise constant no matter on or off the gas. being as I just had work done , it looks like I should take it back to have them look at it . Is been a real hassle. Ive own Yamahas for most of my life never had this much trouble. The sled vibrates too much . It vibrated before I had the bearings changed but now its worse . I did experience the hyfax melting/welding to the skid, I have never had this happen before .
 
maybe not this but sometimes you can develop a vibration by flat spotting the small idler wheels located at the top of the tunnel toward the front. slush will build up around them then freeze causing the wheels to flat spot by not turning. always get under there after a ride and clean them out before they freeze up. that goes for all idler wheels
 
Noises can drive you crazy when you try to pinpoint it but if possible see if you can tell where it's originating from and then we may be able to sort this out for you.If you have a track stand or can tie the back up off the ground run the track around either by hand rolling the secondary,this should provide the best chance to hear the noise,or power the track around and try to hear the noise.

That is a very good point of interest to check out too.I would say you've got a bad bearing in the skid or a flat spotted idler also a possibility is the track check it for tears or chunks missing inside and out.

Have you tryed your backup belt

That is what I was thinking. Burned the belt trying to get it going. I had a srx vibrate and it was they used plastic backers and the stud heads were not sucked into the track enough. Switched to aluminum and no more vibrations. That was after I put new bearings in. Some sleds vibrate depending on conditions no matter what.
 
"When i tried to go again I had to give it some , like throttle to the handle bars to get it to move"

I would try a new belt before I took it back to the service shop.
 
yea I understand what your saying , I did have to give it full throttle , however , the vibration was there before. The belt has made it a little more pronounced.

Yea I see, This could very well be , probably what created problems with the bearings letting go . I will be there when the dealer looks at this. We shall see . I will then let you all know .
thanks
 
Sled broke down on the trail after 45 miles after bearing job done. After inspection looks like the tension bolt has backed way out , lock nut backed off . It made a loud noise , then cluncking bad under load . I stopped on the trail and had to call a friend to pick me and my sled up. Man I am very mad . Its going back to the dealer to be fixed . I am not going to pay for this . I will keep you posted as to what happens next.
 
The dealer fixed it , replaced the chain at no charge to me and the tech apologized to me personally . That was kinda nice.

now I took it out for a trip and another 21 miles or so and the thing starts running on 2 cylinders, changed the spark plug and no change , pulled the plug wire no change swapped the wires and then the other plug didnt fire ahhh, I think its a bad coil . Its the one closes to the clutch . I am very disappointed . Everytime I gone out with this thing, Ive had to get the trailer and bring it home . What is going on , one thing after another . I am really starting to think next year Im going to get an new apex or nytro. I dont know , just really discusted. :o|
 
So could the track sticking to the hyfax really cause the misfire feeling? I left my sled out over night for the first time a few nights ago. IN the morning I went to take it out, and it seemed like it didnt want to move over icy snow. I thought I could smell the belt burning also. This got better, but when I hit the field it started missing on higher rpms. I brought the sled home, check the exhaust valves, and changed the plugs. Took the sled back out and it ran great for 20 minutes. Then started doing the same - missing at high rpm's.

I just started using yamalube oil, and yesterday was the first time I started using an electric shield.

Any idea if athe track sticking could be my problem?
