[QUOTE="mas2de, post: 1351064, member: 106477"] MX guy, I Love my 4 strokes. I don't do much racing, but as long as you take some care of your 4-stroke it will take care of you. My dad has an 81 Honda XR 500 that has been run for probably a years worth of hours (if not more like 5 digits) by now and he has never gone into the motor at all and it still pulls his 280lbs up off the ground up to 3rd gear. The 4-strokes that I've ever seen never need any difficult maintenece. Just clean 'em, tune 'em and ride 'em. I have not been in the 2-stroke world very long but alot of my friends are. For the ones that like to race, they spend half their time rebuilding their everything and fine tuning and twiddling. (but then again that Is racing) But the 2-strokes have most always been lighter (fewer parts), more powerful(power on every down stroke as opposed to every other down stroke like 4-strokes), and therefore faster(also more responsive to throttle because of the cylces). But today's 4 cycle bikes are just as good as 2 strokes as far as I've heard. The 2stroke power is usually less managable and more abrupt. The power valve in the exaust helps to control the power curve but can be finicky and difficult at times. They are also hard to work on. For any beginner I would say 4 stroke because of the reliability and ease of operation and maintenance. BTW MATT90GT, NO valve should EVER make any kind of contact with the piston. That would extremely damage the valve and it won't seal right, and also extremely damage the piston and gouge it. If you have any valve hitting any piston you need to tear that motor apart. Good luck MX guy, Mike [/QUOTE]
