Congrats on the clean cr250 find, there,s a few out there yet. I know a local expert who has 3 cr250,s. The rider and his dad say the rad valve has a good low to mid increase, much better than the vforce which is better than stock. He runs a stock cylinder. I would get a pc pipe, most use the shorty silencer to gain low to mid quickness, the rad valve will give ya alot more low to mid than a shorty thow. You could go with pc,s McGrath replica porting, with traction it,s a 450 killer they say. The stock cr like a mix of race fuel, squish band is a little off. Throttle jockey make the retro graghics, 1986 des nations, 1995 1-800-collect,etc. I think the stock graphics look great.
