I am no expert, but I ride sleds, motorcycles, atvs and boat (jet ski and 23 ft cabin cruiser). Maybe its me, but sleds seem to crap out waay too easily and quick. Rust and corrosion is hardly controlled (better coatings and paints would be nice). I haul only with a cover, and coat everything in WD-40 when possible.
For example, I leave my lawn mower full of gas, maybe change the oil, and it runs every time. Same thing with motorcycle. Gas and go. The sleds I've owned (current excluded) need absolutely fresh fuel, good oil, every bearing fawned over with fresh grease, clutches watched closely, drive train maintenance, etc.
If you don't, then failure, and trip or weekend is ruined.
I have found using synthetic grease and oils have reduced the failures, but it seems that unless you buy a new sled every two to three years, it will ruin a trip like what happened to a buddy last week in the UP. Just venting, but it seems like our failure analysis people at the factories are sleeping on the job. I would like to see sleds reliably run for 8 to 10 years before completely falling apart, especially after spending $10,000 plus.
I plan on moving to a 4 stroke with my next sled when I get some cash. Anyone else feel like this?
