That cr250 is 2000 or 01,great rider, you can go back many years on a 2-st bike and be competive. My 1st ride last year,1st time riding my stock cr125 06,with just stiffer springs,icat, pc silencer,at a friday night track I never rode before on a sunday,with 100 riders at the track. The winner in 30a class friday night that was a special thripple cross event, we went at it back and forth, I would pass him in the corners,he would pass me on the straights. He,s a regular at the track also, I put a rad valve on since and the cr runs much better now. I know of alot of folks that bought 2-st., that where hard core 4-st. Then got into much better shape,and there having a blast riding again. When I rode my 04 cr125 ported,40mm carb,etc. everyone would say I love the way your bike sounds, how many 4-st riders get to here that. haha

Sounded like a cat getting eletricuted or something.
