Last night at KilKare in Xenia I rode two 14's...the first was bone stock 150 miles on the odometer,the air at the track was terrible...somewhere around 3000' would be my guess.The second bike was Brock's 14 from the diary off dragbike.com,I went 9.94@ 140 on the stocker.... and first pass out of the trailor I went 9.28@152 on Brock's this was with a missed 3rd gear...the bike did go 6.05 in the 1/8. with a different clutch(stiffer springs) I think teens would be no problem on brock's.I love busa's but that 14 is pretty sweet....to go those numbers not being a kawasaki guy or having ANY time on kaws since 1988 speaks highly of the 14 and of the brock set-up on the bike.
