I have an 01 CR250 that lost compression. I'm thinking that the piston might of disintegrated. My dad said fix it sell it and get a newer 450, which would take most of my money. Or i could get a newer 250sx, for a little cheaper hopefully. Or just keep putting money into my bike. Im not one of those crazed 2stroke lovers, i just like the simplicity of them. obviously it doesn't matter which one i get i'm going to drop a lot of money into it. but it just seems like there's more things that could go wrong with a 4stroke. What do you guys think??? 2stroke, 4stroke, or keep???
