lighter springs
I had a mate who had an FZR thou' in the early '90s, it was a regular contender at 'run what you brung' drag events.
He had to fit much stronger springs in his flatslide carbs since with a forward sloping motor, inertia was keeping the slides open under heavy braking regardless of shutting the twist grip. Not such a problem on the drag strip but pretty scary on the road.
