Welcome to KF. I have not ridden the late 90's zx6's to really know what mods would be appropriate for you. But good luck.

 

Thanx anyway but i know one of you guys can help me out but thanx cause at lease you reply.

 

What was the stock rear sprocket before you put the 43? If you added more teeth, this will increase the bottom end but will take away the top end. By the way, the 1997 ZX6R will not go 170. The speedo on these bikes is about 10% optimistic. If you are going to drag race the bike, I would stick to the 43 sprocket. But, to make a late 90s sport bike beat some 2002 on up bikes, maybe nos would help. Practice your hole shot, its very important. This drag race will be happening at a track correct?
