Well I asked because I recently bought a '97 YZ 250...which is my first 2-stroke bike (used to always have 4-strokes). The engine was rebuilt a couple years ago, and has only been riden a few time since then.
I almost always ride at the coast (sand dunes) with this bike and was just wondering what the average engine life would be for that type of conditions. I also like to ride real hard, but have been kind of worried.
So is it generally because the engines are run at such high rpm's, or is it lower rpm's that are hard on them?
I was also a little nervious because when I would re-build 4-stroke engines, it would almost always be over $500 in parts....and that's getting them at a discount! (but I guess there are a LOT less things to break in the 2-stroke engines).
