Hi all. I have a stock 99 busa i use for drag racing and have been getting clutch shutter. Its good for about 3 or 4 passes but when the bike is hot is when the problem is at its worst. I have had the BTL welded and i am using heavy duty springs. Apart from that everything is stock. Any suggestions? Do i need a brocks cushion kit?
