Track visit with new swingarm in better conditions
Repost from other forum. Sorry I'm too lazy to retype. 2009 ZX14 Monster Edition.
The local track was open today so, with nothing better to do, Sam, Dave and I decided it was time to play. Dave put waaaaaaay to much pump gas in the bike so Sam made a couple of unmemorable passes on pump. First pass spun badly, second pass forgot to hook up air shifter. :
Here are the incrementals from where the bike simply sat still and made tire smoke off the line. Not pretty so don't laugh.
60' 1.533
330' 3.983
660' 6.043
MPH 118.64
Not much about that pass worth posting but in the interest of full disclosure, there it is. After making two passes Sam turned over the riding duties to Dave to let him get used to the bike. Still had two bars showing on the gas gauge of 87 octane ethanol blended fuel in the tank. Yuck. BTW, rode the bike over an hour to the track. No trailer action today.
First pass with Dave he just rolled it out to make sure it was going to go down the track with him on it. Lots of pump gas in the tank still. Incrementals were:
60' 1.646
330' 4.066
660' 6.014
MPH 126.53
DA -753 on this pass. Finally no head wind.
Less weight = better MPH for sure, huh? Now after this pass the fuel light still wasn't blinking so Dave took off and rode the bike around for almost an hour to run the pump gas out of it. Yes, we tried pumping the gas out with a syphon pump but it just isn't that easy with the 14 gas tank the way it is. So after that Dave drove straight to the staging lanes and ran:
60' 1.708
330' 4.187
660' 6.184
MPH 122.85
DA -851 on this pass. Still no headwind but a slight crosswind.
I'm ready for some MR9 but there's still pump gas in the tank. I don't normally do this but I just dumped a quart or so of MR9 right on top of the pump gas and switched to the MR9 map. I know this didn't give the full power of the MR9 fuel and tune as compared to straight MR9 but I felt like I had to do this. We will NOT go to the track with over half a tank of pump gas ever again.
So far things looking pretty bleak for team "Smokinstorm", huh? Well, Dave was starting to get used to the clutch and bike in general at the track and made what I thought was a great pass for him at this point in his learning curve. Took the launch RPM up to 4500. A little higher than his previous launches. Incrementals were:
60' 1.449
330' 3.776
660' 5.739
MPH 125.89
DA -578 on this pass. Bike actually wheelied a little in second gear on the shift and carried the tire a couple of inches off the ground. This isn't supposed to happen at the 71" wheelbase that we were at today, right? The pass looked awesome. Hard launch. Wheelie in second insuring the bike was accelerating as hard as possible. No way to improve on this pass so I'm happy for today. Well, Dave came back and said he felt much better about the clutch and bike now and was going to try something. Sam launches at 7000+ RPM all the time and Dave wanted some of that action. He actually launched around 6000. No way this works for a 160 pound rider. The pass looked smooth, uneventful and rediculously slow and it didn't immediately sink in that he had just raced a 6.0 bike and beaten him to the finish line by 25 yards or more while leaving at the same time. I was down track watching the pass and couldn't figure out why Sam started jumping up and down when he got the time slip from the tower. I got to Sam about the same time as Dave and realized why Sam reacted as such. Incrementals on this "slow" looking pass were as follows:
60' 1.376
330' 3.647
660' 5.565
MPH 125.00
DA -563 on this pass.
Oh yeah, new best on the old outdated ZX14 by a significant margin. Maybe this old "Kow" has life left in it after all and doesn't need to be sent off for slaughter just yet. As long as we can keep this kind of air around here for another month or so (and we should in eastern NC) Dave will continue to improve his riding and the times should continue to fall. We're also heading to Cecil for a MR12 tune for another small horsepower bump soon. We've got enough MR9 for one more trip to the track. Still has both front rotors on but one of them should be coming off soon as well.
That's the report for now. No, we're not the fastest "almost" stock ZX14 now but we're far from the slowest as well. I know it's going to be tough but I'm hoping to keep pace with the 2012 14R as times roll in on those bikes and continue to drop with guys like Lee (SmokinZX14) and Ricky piloting them. Wish me luck everyone. I'll need it. Thanks for reading.

your bike will go 5.40s maybe pop a high 30 with the light rider. there is still a tenth left in that 60 but that will come with seat time. its still going to carry the front tire at that wheelbase. it just shouldn't get crazy. tell your light guy to launch it at 6800-7000 . I'm 160 suited and that's where I usually launch. the key to knocking that 60 down is having the throttle pinned by the time you pass the tree. a data logger really helps to determine that among other things. but congrats on the new best time but I think the best is yet to come.

I asked Dave where he's hitting WOT. He said that today the earliest was right at the top of 1st gear, right before the gear change. There's .01-.02 right there I believe if he can lock the throttle right off the line. He's just not used to a big heavy bike with stupid torque like the 14 and I certainly do not want him to do something he's not comfortable with this early. It's a long season ahead. Dave's been running mostly stock really long GSXR1000's and those were the earlier versions. He hasn't been drag racing but a year altogether. Somehow I was hoping the bike might hit 130 or at lest scare it to death like the new 14R's I keep reading about but that performance number is further out of reach than I'd planned on it being. Taking one front brake rotor and caliper off and retuning for MR12 might, at best, net me another MPH. The rest is going to have to come from going WOT the instant the bike moves and even that might not be enough. Might have to wait for some motor work after all. But hey, it's a goal. BTW quick6, I sure hope you're right on the high 5.3x. I almost hate to hope for that as I'll probably be disappointed but seat time, lighter weight especially unsprung weight and a few more ponies sure look promising.
