Ok. Battled my sidewinder since new and the only way I could keep belts in the thing was going to an old nytro primary and secondary. Put 2000km on last season with zero breakage and zero clutch rollers or weight bushing issues. I do however, have wear on the inside of the belt. I do use the 8DN...

Ok Yamaha gurus. Doing a track install on the sidewinder and have some wear on the nubs of the drivers. It doesn’t look like too much but would you suggest changing to some new ones? Sent from my iPhone using Tapatalk

Got 7000km out of my OEM 162 Powerclaw on my 18 Sidewinder. What track have guys used that hold up well? Am going to stay with 162. Also need to replace the drivers so a pitch change is possible. Sent from my iPhone using Tapatalk

Just put a secondary from a Nytro on my 18 sidewinder. I have a 47* straight helix, epi purple set at 1-0 and 2mm of end play in my setup. Is this a good starting point or is it out to lunch? I am running the Hurricane 270 tune. Thanks, been battling this thing since new so trying this clutch is...

Has anybody added extra vents in the side panels of their SW? I am putting in some specifically on the clutch side to try and rid some heat, and am using a mix of some random Doo and Polaris vents that appear to fit where I want. Panel strength is a concern as the Sled ends up on its side...

Some adult language, but this is pretty funny. https://www.captiongenerator.com/2151147/Sidewinder-clutch

Recently swapped over my Sidewinder to a primary off of an Rx-1 / Apex (not sure exactly). Put 500km on with zero wear on the roller bushings and everything was looking great. Went out yesterday and approx 85km in went to pull out a gram of weight and noticed the spider had lost all the...

I feel like I’m beating a dead horse with clutching on my 18 50th 162. Been fighting belt and primary roller issues for 2 seasons. I bought the Hurricane alignment tool this fall and it showed that my secondary needed to move inwards about 1mm. I’ve had two dealers at separate times align the...

Tough to tell but I have a gap prob 40 thou that looks like the bearing isn’t seated against the housing on this stub shaft. Can anybody tell me if it should be pressed in more?

If I adjust my belt deflection on my 18 162 to 0.5mm under to 1.5mm over like the manual says it wears belts out like in the pic. Does anybody else have to run the belts lower in secondary? I have been using 8JP belts. I usually have to run the belt about 1.5-2mm below the edge of secondary...

Cleaning clutches tonight and find all three weights are toast. What is the Dalton weight I need for a stock 18 SW 162 with a cold air and CR muffler? Stock tune. Also almost every ride I have a primary roller get sticky. So I pull it out and find the bushing starting to come out. This has...

. Blew a belt yesterday, but on a positive note, I did get around 700km on this last 8JP. Was pretty deep in Renshaw and have been riding hard all year. While picking the belt pieces out I found this plastic part in the belly. Have no idea what it is from. Looked through all the parts...

I have an 18 sidewinder, it uses the same rails as the new Cats. Installed the Iceage brace kit after I bent the first set this year. Just got back from a trip and see they are cracked. No tail landings and don’t recall hitting anything noticeable. Never bent a set of rails on any machine...

My 18 has been a belt eater. Stock tune. MTX weights loaded with heavy rivets in all locations. I put high torque secondary rollers in, Dalton 35* billet helix, black/orange spring. Primary spring broke and put a black/bronze in there because that’s all I could get in a short timeframe...

Broke a primary clutch spring on the weekend at some point. Anything to look at as a cause or do they sometimes just break? Stock tune 2018 MTX 162.

Anybody know what Dalton weight is comparable to the OEM 8LR00? Cant get the 8LR00 in time but can get the Dalton stuff everywhere. Its for stock tune 18 Sidewinder with CR intake/exhaust. Thanks

Having a coffee this morning going through S&M and thought wow, its been 20 years since I first tried snowmobiling in the mountains. Living in central AB growing up we always had a sled around the farm, but some years it never turned over due to lack of snow. My dad had bought a 1979 Arctic...

Is there any way to prime the oil pump on these machines. Reason asking is I have a 16 RMK 800, 3600kms on it but on its 3rd motor. Every time it goes down is within the first 15km of the first ride of the season. Machine is stored in a dry place right beside the other sleds through summer...

Sled is bone stock. Cleaned air filter day before last ride, unloaded and rode up into alpine with no smoking or issues. Stopped for a few minutes to gather before a climb into the zone we were going into. On the climb the sled was smoking really bad and running poorly. Open the air box and...

Did the first oil change in my 18 SW last week. I let the motor and oil tank drain over night and filled the next day. It took 3.6L to get it to read in between the min-max line once warm. The service manual says 2.8L. Checked a few times since and does not appear to be over full. Does this...
