I currently own a bone stock 93 xr250L. Its been a great little bike and will go ANYWHERE I want to go as long as Im in no hurry. Ive got new bike-itis (the urge to buy a new bike) . The new fuel injected CRF250L caught my eye and the price tag is very attractive. Could someone give me some input of engine power difference between and old air cooled 250 vs new liquid cooled fuel injected 250 . Also interested in the CRF250X which I could get licensed for street. What are the differences between the X and the L. Would the X model have the same longevity as the L model?
