It seems I'm never quiet happy with the car/bike I pickup. I always seem to want it to be more efficient and/or faster. Then again don't we all do things like this anyway? Any suggestions for cheap bike, preferably under or around 3000 and somewhere in the realm of 600cc+ bigger the better, either naked bike or crotch rocket? I'm just looking for recommendations at this point. That too I'm clearing the space ahead of time.
