Was pointed out to me some inherit problems with a sled I purchased as a starter sled for my fiancé s son, so I thought I would start a post seeing what sled people have owned that were their least or most favorite, which for some may not necessarily be the newest or the oldest they have owned. For me... My least was my first, which also got me into small engine repair as I had to fix it for hours to ride it for minutes 1972 bolens 440 sprint with a JLO engine in it, was young, bought it with own money and I wouldn't even begin to know where to start with issues, oddest thing was had a solid rubber track for bogies but had 2 metal slide rail assemblies that rode against the rubber and lubrication was an issue so kept a bottle of dish soap to provide lube between rails and track. My favorite so far.....1992 skidoo mach 1, had performance rotary valve, clutch kit, fast fat boy pipe, always liked how they looked, handled and rode. I picked one up just to have it a few years back that is in excellent condition and engine built by russ lemke, doesn't get out much and no one else touches it, just have it to have it, still my fav.
