. Top ride, I had one of these bikes too.
So did i, they're a top bike for their age! Mine had a magnum pipe, and keihin race carbies with 39mm throat size and accellerator pump. The standard carbies are only 27mm so it was a fair size difference. Size does matter, it was about 20 HP increase with the pipe.
I never investigated it, but the main difference between the 90-91 model and the 92-94 model is the cams, apparently the 90-91 (J) was limited to 100HP for import reasons (Australia was going to have a 100HP limit on street bikes, which never eventuated) so the cams were changed in the next model. As far as i know if you go to the trouble (not sure how expensive) of changing cams, you can unlock some more power aswell.
sweet ride!
