had a KLT250 that constantly had electrical problems, it was one that you couldn't take to a trail without having to drag it in, so I never took it out of the yard. Bought a 87 Suzuki 250 quadrunner 4x4, I'm sure it was a good machine when it was younger, but too many years of abuse and lack of maintenance before I got it pretty well ruined it. I spent a lot of time and money trying to keep it usable, ended up selling it for parts. I tried a couple of the chinese kids quads, they both had thier issues, but it was usually a wire breaking or something like that, quick fixes. It seems to me that if you buy a good air filter for them and change oil immediately after uncrating it, they will run a long time....but the stock air filters on them are crap.
