[QUOTE="NJGregsCR, post: 1323413, member: 75711"] I've really had good success with my 97 CR250R with mods to make it more rideable. It still has freakin awsome power if you wind it up, but I wanted smooth lowend delivery for woods riding. If you want to detune a 2-stroke so you can "putt" around here is what I did. Major improvements were- Flywheel weight, I went with the max oz weight. Steel clutch makes a big difference. Quiet silencer restricts back pressure and the addition of a DB Snorkel helped. 51 tooth rear sprocket was good. FMF Gnarly pipe moved the power hit lower and gave more bottom end boost. My jetting was good to begin with, so I was lucky. The jetting has alot to do with rideability of the bike. If you do the mods and get the bike running clean, you can just putt thru the gears and enjoy it. You'll still have the power reserve on tap by just twisting the throttle if you want. [/QUOTE]
