Buddy went 9.80 at 148mph on his zx 10r this weekend. brand new nothing done to it at all except -1 tooth sprocket. he weighs 165 pounds and had a 1.71 60 foot time which isnt the greatest and still ran those times!!!! not bad!!! no exhaust or anything!!! HE also owns a busa and can only run 143 mph on that with full exhaust and pc. his 60 foot is 1.61 on the busa and it still loses out to his 10. found that pretty interesting!!! especially when he was doing back to back runs on each bike!!!!!
