WOW, what a night! I got in probably 15ish passes (6 of which were licensing passes), and I hit my lofty goal on the very last pass. I was having a difficult time getting used to the extensions. I couldn't really get used to launching SO hard.... and my best 60' was only 1.56. My final pass was a 9.56@142. All I wanted to do was get in the 50's.

New tow rig for 2010 with my trailer and bike all loaded up. It actually pulls nicely. I thought I would have to manually shift it all the time, but the diesel makes good torque and can pull top gear up anything but the steepest hills.
juuuuust making sure you're still back there
29.5 mpg isn't too bad either.... I got 34.7 mpg on the way home too!

I'm having a gearing problem right now. My current setup is 16/43, but it puts me on the limiter just before, or just after the finish line. On a good pass, the bike either keels over 50' before the finish line on the limiter, or I have to do a short shift to 5th. For the time being, I'll put my 41 stock sprocket back on, but are there any other suggestions. I don't think I really want to gear anymore because I am foot shifting, and it's difficult enough to get my feet up in time.

You should try 16/46. If you have an agressive launch it works really well. I stage at 7k rpm, snap the throttle open as soon as possible and slide the clutch to about the tree. I'm a firm believer that if you weigh more than 160lbs that the pizza sprockets are the way to go.

Good job Gilberjj on getting the license and hitting your goal....
15 passes in one night is a good day/night at the track.
I'm not sure on the direction on the direction should with gearing.
Try the 41 and then work your way back up....

I've always liked the red 06! Maybe everything but the brown wheels and forks.
I'd suggest a smaller/ lighter trailer to you if you're concerned with mpgs.
I have a two axle enclosed V-nose that easily fits 4 bikes but for the short haul and around town
I use a Kendon stand-up that my Tundra don't even notice

Went to the track again on Friday. Weather wasn't quite as nice, and the track prep was not as good, but I still got more consistent. It is a lot easier to ride this bike now that it's extended. I'm still trying to find the best way to launch, where my mph is, and still optimizing the set-up. Here are some pics.

gear that sucker as low as you can to get it running through the traps near the top of 6th!
The mechanical advantage will be yours, and with the solenoid mounted right on the ram you can probably get away with .40 miliseconds kill and near zero delay!
you might even be able to get away with less kill, the zx14 has very slight backcut from factory.
If it was a busa 2nd gear would be done trying that, they are straight cut and famous for rounding 2nd gear

It took a little while for wheelie to convince me of the pizza sprocket and once I finally tried it, I wouldn't go back. I run 16/48 which is a little much to ride on the street. I'd try 16/46 if there are many street miles involved. Just try it, it's only $65! (sound like a crack dealer talking to a young kid)

I'm working on getting a new one, but I really haven't decided between 46, 47, or 48. Since I'm still footshifting, I think I'll try a 46.

Not to disagree with what Lyle is saying, but...
Mark from R&D has told me that the ZX-14's have no backcut. Inspecting my own spare trans seemed to confirm that. If it has a back cut, it would have to be very little...not visible to the naked eye...unless perhaps they changed them over the years?
I had a trans done by R&D, it is their pro-cut trans. It has a special cut on the face of the gears, for racing use (at the expense of downshift quality)...even with that, the minimum suggested kill time is 45ms. I think 65-70ms is what is suggested in most cases. FWIW, I have the max kill time dialed in, and the solenoid mounted on the ram. If you look at my onboard video, you can hear that the shifts are still lightning fast.
Regarding gearing, run what works best for you. The fastest guys on this board run 16/41. Sure, they are 50+ lbs. lighter than most...but you don't need 7 gear teeth to overcome 50 lbs. of weight. It's all in the technique.

I am literally double their weight. Thanks for the input though guys. From watching the videos, I think my gearing could change a little. Practice is what I need the most, but I'm either hitting the limiter in 4th, or shifting into 5th at the stripe. I am going to try a 46 tooth I think. From the vids, it sounds like the clutch is out by the tree, but it's bogging. I need a little more throttle, and a little more clutch I think....

Here is a little history on my bike.
It was one of the very first in western Canada, I picked it up April 2006.
it had crate damage, I saw it before it was PDI, some of it looked like the bike may have been used, and it took 2-3 weeks extra time to show up at my old local dealer in a remote area northern alberta.
it had single lip seals in the wheels, and the replacements I bought are dual lip.
the other 14's I worked on all had dual lips wheel seals.
What do you guys have in your wheels?
the trans looked to have about a 5 degree back cut on them when we dissasembled the motor. My FBG backcut is very noticable, at about 20 degree's from what i recal.
My mechanic friend who has had all these motors apart was very suprised to see the trans that came out of my bike, and actually pointed this out
My bore with 6000 miles on it was still like new, cross hatches still clearly defined and the bores perfectly straight. However, my bores all measured .0004" beyond the service limit.
It was a loose, but very strong motor compared to the others I raced and rodein same stae of tune.
( I uncorked it June 2006 with Brocks pipe before there were any others local to compare it to stock for stock)
it has been the fastest zx14 of all 7 I compared it to.
I had my muzzy digikil set at 40 ms kill, and 40 ms delay.
Once I put the solenoid on the ram I left the kill alone, and gradually reduced the delay to zero. my regulator presure was set for 160 psi, with the soelnoid directly bolted on the ram.
There are many guys in the dragbike forum running sub 40 ms kill from what i recal.
I don't know what to say except what did they do with all the press intro bikes in Vegas from 2006? I really wondered that.
I would swear on my fathers grave, this is what I have found with my bike.
dispute it all you like.
min 65 -70 ms is for kill and delay.
wheelie does well with staging at 7000 rpm, with the big gears, and an air shifter will be required.
I couldn't get my foot up fast enough to shift to second before hitting the limiter, or short shifting to prevent giant wheelie with 16-41 gears on the street ( no track where I used to live) , so lower gears would make it nearly impossible with a good 60 foot IMO.

I am only going by what Mark at R&D told me, what I saw with my own eyes, and my experience at the track with the airshifter. I'm sure you are aware that some kill boxes don't have separate adjustments for delay and kill.
I'm probably not as knowledgeable about these things as some, so I will defer to the experts.
Btw, no need to swear on anyone's grave over this. We can only go by what we have seen and experienced personally...this isn't an attack.
