I have been travelling for 3 summers and my 4-stroke Subaru is running fine, though the roller on my Staton friction drive has worn smooth, but runs fine in dry weather. The people on this forum, tend to go with quality systems for touring. I ran into a couple who were using "cheap" 2 stroke kits from King motors (which is having a huge sale, i notice) and Wally world trailers to go from Florida to Las Vegas, New Mexico. They had some fixable problems. So I say go for it, especially it that is what you have, and especially if you realize you can always pedal. Frankly i would probably just ditch my rig if it failed, with a "free bike" sign. Generally were talking $500 bucks, i've already got my moneys worth, in fact it has more than paid for itself in all the beer and food the curious have given me. People routinely ditch more valuable cars. I think it is important to get a free bike or $25 bike from a garage sale. To me that is the point. A motor turns a $25 bike into a $5,000 bike performance-wise. I've blown past the lycra types up mountain passes, though on some terrain they can beat a "heavy" tour bike (clap-clap, polite applause). Last year I went over the "Gila Monster" the same day as Lance. I had a motor of course, but then again he had a 15 pound bike, a police escort, a support crew, a hotel suite, etc, etc, Way to go, Lance! So, just do it. Sometimes i regret just starting with the cheapest kit out there, because there is a learning curve, and my O.K. system took a couple falls, and power-outs, and roller wear caused by a too good Kevlar tire, which grabbed road tar like a magnet. You can always upgrade, later.
