ive only had my bike for about 2 weeks and i havent got the chance the take it to the track, so i dont know what it runs. It is a 1993 ninja ZX6 with K&N filter, advance timing, Yoshi pipe, Ram air, 2 teeth of the front sprocket and one added to the rear, stage one jet kit and a 420 light weight chain. the guy i bought it from said with those upgrades took it from 86 stock hp to 102 hp.....? One of my friends buddies said it wouldnt even run a 13, i find that hard to believe, what do you guys think it would run in the 1/4? Thanx

 

HP sounds a little high & the chain is probably a 520 instead of a 420. It should do 12's or less in the 1/4. My 85 did a 12.202 with a jetkit & ignition advance rotor, stock pipes & stock gearing.

 

hes -2 in the front, hows that working out for you ?

 

His buddy says he won't see 13's. He should be able to do atleast 12's or quicker with that gearing; depending how good of a rider he is.

 

that gearing should put the bike in very high 11's low 12's, i said the bike though. can he get it there, i dont know.

 

For reference, my 91 ZX-6 with just a pair of Jardine RT-one slip-ons did consistant high 12's with a best of 12.6 @ 105 mph. This was also with a easy 5000 rpm launch and barely any clutch slipping. I launched at 6000 and speed shifted (no clutch) on the fastest run, but I think it was because I folded the mirrors in.
