I used to have a little crotch rocket when I was 20 years old.It was a Honda CBR...It was only a 600cc but it had a Yoshimura pipe and jet kit and the sprocket had been changed...

That thing didn't even start pulling hard until 6500 rpm...tach red lined at 13,500. Back then I never really contemplated what would have happened if a rod would have kicked out the side of the block at 135 mph. :? That was my first and only bike.
It's a miracle I lived . :lol:
Those were the days.
