I know four strokes are taking over the Mx market for sure...but I just cant find it in me to sell my kx250 and get a four banger.
The AMA (not the model) will allow a 250 2-stroke to race in the 250 four stroke class next year. A two stroke 250 makes about 10 more horses then the 250 four stroke.( i think I know what class Im racing next year ) Fourstrokes have come a long way though.
A properly tuned (jetted) 2 stroke does not spew out clouds of smoke. in fact, once my bike is warmed up, you can hardly see any smoke from the exhaust.
