Well I don't smoke so that helps. I always had boy-racers ie. light frames with overpowered engines. My fav was a bike that was 10 years older than me, a Yamaha YR350 - a 70s frame with a late 80s engine. Meant that it was a star at straight lines but a complete donkey at corners. You could lean with your knee touching the ground but it would still go straight. :P

Never really lived in cold places.
