mxracer-Maybe one of your friends ran different fuel or rode differrently and that's why the plugs fouled? Alot of things can cause that. Anyway, just do like mxracer said. Go find a used one, call they owners and ask them if you can come look at it and ride it. That's what I did when I bought mine. I was used to a four stroke, but had ridden a CR 80, a piece of crap one that is like a 1990 but was an 80 nevertheless, and when I went to look at the Cr that I ended up buying, the guy had no problem letting me start it and ride it. You should find some in the classifieds and call 'em and tell them you wanna ride it, but make sure it's one that you might consider buying, otherwise it was like a joy ride and nobody likes somebody just coming and riding their bike for fun and not being a possible buyer.
