OK, technically this doesn't have to do with a 4 stroke, but it is relative to my original post. Another 93 KDX200 went up for sale relatively close to where the XR is located. It has a Pro circuit pipe and silencer also. He's asking $1000. Now, my concern is should a begginer like me start with a 2 stroke or a 4 stroke? Honestly I like the KDX a lot better, I want to take a run out there today to check it out. I would have to see the KDX first, I don't want to buy that out of excitement and find it was a bad choice. I like the power of a 2T, but I've never experienced it on a 200lb frame with 2 wheels, only a 700lb snowmobile :) .
