guys in your life time of driving cars and riding bikes.....you would have come accross examples of the same model vehicle, same engine, same transmission, but one runs real sweet, and the other 'identical' example just runs ok. soem people say a country car/bike will run better thans a city one because it is used to high revving. soem will say that if you baby a brand new engine while its brand new, it will never really run as good as one that has been run in hard. in the last 20 years i have had 2 'babied from new cars' and about 4 'country' cars. the 2 babied from new ones, never revved out without protest. the others revved their tits off, including my current vehicle, VE holden. i now have my first brand new vehicle ever. Suzuki M50. it is a cruiser, but i want it to rev, and get used to high revving. what are your thoughts?
