Land Speed 2012 ZX14R finished! Pics
Hey everyone..................
I finally finished my bike minus the metal battery box and holders, safety wires, and BMC race filter. I need to data log her at 4200 ft and about 90 degrees. We have some roads here in southern Arizona and over the border in NM that would be perfect except for the fact that it is totally ILLEGAL!!!! We'll see. Here are my mods and some photos.

Thanks for the suggestion. I don't think my bike will hit 231 mph. I am set up so My bike will redline at 216 mph and the center of my peak power is at

Sorry,
My 4 year old sabotaged my post........ Peak power is at 10,300 so I want to be around there at top gear. With my hp being just over 200 at 2600 ft elevation, I should be able to pull past 200 mph at 4600 ft with proper data logging. (If I just confused you, sorry...... I have 2 screaming toddlers climbing over me and I can't think...... Any way, I just want to get past 200. 38 tooth is too tall. At 200 mph I would be at 9600 rpm and that's below center of my max power.
Maybe I'll change to a 40 after a few test runs.... Thanks again!

You mentioned 4600ft you aiming at Bonneville ?
Take a tall sproket anyway , i have found you rarely go much slower with the unlimited distance geared too high , gets you in the ballpark then when you know your speeds you can optimise gearing to get the last mph or so
in 2011 we were running a pretty std busa when the race bike did not clear customs in time
and playing with tires testing , one of the options was a lsr tire mounted on a custom rim, and the only gearing we had was 34t , busa was otherwise running a 40t rear
busa ran consistant 186mph with the 40t and consistant 182 in 5th with the 34 t
I think a lot of guys under gear there bikes and discount torque , max speed may not be at peak hp but somewhere lower , gearing options let you find out

Yeah, I was told to bring extra everything..... Chain, tires, sprockets, etc......... I'll bring a 40T and 39T rear. They are cheap enough................. I just want to make sure I'm shifting in the power band and utilizing all my power at top speed....
Thanks!

Where are you going to run. Texas, Mojave, Bonneville?
While I've never been to Bonneville, I've done The Texas Mile and both The Mojave Mile and the Mojave Magnum (1-1/2 mile).
You'll never meet a greater bunch of people, both staff and racers.
Like it has been mentioned, bring lots of gearing, spares and gear. Conditions can vary immensely. One day I ran 18/39 gears and the next day 17/40. These events are run in the middle of nowhere so coming prepared is very important.
Also, READ THE RULEBOOK. I have seen more than one guy show up and have to deal with issues that were clearly stated in the rules. Kinda sucks the fun right out of it.
If there's anything I can do to help, let me know. The more guys from AZ the better, especially Kawasaki guys

My bike's specification is very similar to yours and I found that one tooth less at the rear was good for 203 in a mile. I even think it would do it on stock gearing with the Brocks flash ECU giving an extra 500 rpm. I would start like that and only gear it higher if you hit the rev limiter in sixth.

Yeah, I have my gearing set at 216 mph top speed and I know the stock motor won't do that at the salt flats based on other similar bikes. You go much slower, so I think I'm right on. I definitely don't want to over gear on my first run.... I know that at 200 mph in top gear I'm in the center of my power band so I don't have to worry about not getting there with current setup.
Thanks!

If you have the power to potentially do 200+ on the salt you should look at adding ballast
biggest single issue you will have that stops you reaching that potential will be wheelspin
extra weight is no hinderance as long as its placed where it does not upset the balance of the bike
Busa's are easy with there boxed swingarm, fill it with shot and you have about 60lb
the zx14 i built has a longer swingarm and weight box in front of the tire
it is turbo and will need more weight than you ,
if your going to Bubs or WOS and see an Aussie flag drop in and say hello

Thanks Bob, great run and good info......Question, is the older 14 gearing/tranny different then the new 2012R? Secondly do you think a 'stock' 2012R could pull 11,000 on the motor in a mile?
Cliff
P.S. - I'm told you lose up to 20% of your power to on the 'Flats' to wheel spin. What do you think?

Thats a 1350,i think done on the same day as Ralph ran the production zx14r to 208
1650 class records are 223mph for SCTA, Ask Landspeed Larry about that one
and looks like its an open record for AMA /bubs

Cliff, gearing differences Gen1 to 2: The primary gear changed from 1.541 to 1.556 between Gen1 and Gen2. The ratio for 1st went from 2.625 to 2.611 but the other internal ratios are unchanged. The final drive ratio went from 17/41 to 17/42 so the Gen2 is lower geared.
At the stock 11,000 engine rev' limit on 17/42 gearing a de-resticted Gen2 would do 201mph in 6th with no slippage. With the extra 500rpm that the Brocks or Guhl reflash gives it would do 210mph. I don't have experience on salt Cliff, so couldn't advise about slippage on that stuff. I think a totally stock de-resticted 14R could probably pull 11,000 in a mile (not on salt though) in the right conditions with the right rider but the rule-of-thumb for slippage says that it would likely be speed trapped at around 195mph and not the 201 you get from the gearing tables. A friend did just that on a stock Gen1 fitted with a Speedo Healer, hit the rev limiter in top on a runway back in 2006. The speed he was given was 197mph, the gearing table gave 204, so you can see what we're dealing with here.
New14rider, remember that the power curve of the ZX14 is very flat, it doesn't roll off much once it has peaked, so you should consider using all the available revs to calculate your gearing for maximum speed and achieve it at the lowest possible ratio. The reflashed ECU has the engine rev' limit at 11,500 rpm so don't waste that final five or six hundred rpm. Also take off those bar-end mirrors before you run, they will cost you mph. Just one more observation about strapping the front. It isn't just for lowering, it also prevents the front suspension from unloading as the rear end squats when you launch the bike. This makes it much less likely to wheely and allows you to launch harder. Your bike looks like it could be a winner, good luck.

Thanks BobC,
I think the actual redline for the 2012 is 10,800 and not 11,000 as indicated on the dash . That brings us to 11,300 after the flash............ Yeah, the mirrors are just for the street.
When you talk about launching the bike that really just applies to drag racing and one mile courses like Texas mile. It doesn't apply at the salts unless you want to be on your ass before you get out of first gear. Suspension there matters more when your going top speed and your hitting ruts and areas that have been chunked out by other riders. You need your front suspension to go up and down or you will be hydroplaning in some spots (skipping). Plus you can't use straps at Bonneville SCTA (highly frowned upon) Already asked. I know some people have done it, but very dangerous! Especially for such a long course. Your strap snaps and that's it!
Thanks for your reply!!

Interesting that you should say the redline is 10,800 because I always assumed it was too. However I recently emailed Don Guhl to ask this very question and this was his reply.
"Unless otherwise requested, all of Brock's ZX14R reflashed ECUs have the rev limiter raised 500 RPM. The stock rev limit is ~11000RPM, and the new rev limit is ~11500RPM"
Brock also confirmed this from dyno observations. He said an honest 11500 using his dyno probe. Only 200 RPM but quite important when working out gearing !

My ZX-14R 2013 'DG flashed' (dyno graphs posted recently on the HT thread) hits the rev limiter at 11,300rpm, 500rpm over stock at 10,800rpm.......RPM is indeed MPH, if you can pull it.

200 rpm would seem to be a sizeable discrepancy when talking LSR.

Gear it for 11,300 and for 3% slip . Mesure the tire with the psi ur gana use and use all the data on gearing commander.com

little bar end mirrors..... makes the bike street legal. rotate them 90 degrees for street racing (reduces drag) and rotate them back to ride normal. They work great and are easily removed.

Sounds great! At Bonneville I will probably use 42 psi (you don't want a wide tire patch as on pavement). The salt needs to be cut through (not literally) with skinny tires..... less drag and less slip..... The higher the better. I have my shift light at 11,300.
Thanks!
