Ok, so i may have landed an 08 crf50, and my immediate plans are the following: Big bar kit Heavier spring or shock assembly (undecided) Something involving more power Now, I have a potential lead on an 88cc bbr motor. Is there any pro going with the modified crf50 to 88cc engine, versus just splurging and buying a gpx/piranah/z/lifan type motor with around 150cc? Not sure those will even fit, but they say they mount to crf50/70 type motor mounts. I am not sure the direction of this bike, but it will probably be just for effing around. I may however put supermoto tires on it and try to take it to the track. Also, without spilling the beans, what is a good price range on these things? It is completely stock, low hours.
