- 1287 ZX-12R Test and Tune - It's been a long winter, and I finally got a chance to do a little test and tune on my 12R. I have been anxious to stretch the legs of the 1287cc Ace Performance powerplant.
I had not done any high speed riding in months, and my last LSR event was in August of 2009. Suited up this morning I was 230+ lbs (winter and holiday fatness). Nonetheless, I wanted to do some data logging and start tuning the machine so that I can race it later this season.
Here is the setup:
Obviously not the hot ticket for speed, so I kept my goals modest. This day was not going to exploit the potential of the machine. No lower farings, and the big dorky mirrors certainly don't help the aeros. :lol
Here is the LM-2 data logger:
Yep, right on top of the tank where you need to tuck!
But, to cut to the chase...I went to "The Spot". Well, it's definitely not a "Spot" that I want to frequent! All of my concerns about the area were well founded. I won't waste your time with the details...but let's just say that I prefer to do my racing on the track. You won't find me running up and down the roads looking for races this summer.
The bike ran well, but I have quite a bit of tuning to do. In general, it was running rich on top. I did manage to lean it out a bit, with good results.
I also came away with a small video:
Remember how I said that the logger made it impossible to tuck properly? Here I am sitting up off of the logger, at speed, in the breeze:
The bike ran great all day. I put 200 miles on it yesterday, bringing the total miles on the motor to 600. It was certainly no slouch, even with the crazy setup. You'd be surprised by just how fast you can go with your helmet up in the breeze, and no lower fairings! Then again, a few of you wouldn't be surprised I definitely see some very fast times ahead for this machine.
Special thanks to Shiphteey for showing me the location of "The Spot". And thanks to Sal and Ace Performance for building such a kick-ass motor! I went out yesterday hoping to just have some fun...and I sure did.
I'm not sure if the bike will be ready for a May debut at Maxton, but she will definitely get there sooner rather than later.

Thanks Karl. Yes, I am going to be careful. I don't see myself making any more "full" passes out on the street. Maybe some 3rd-4th gear pulls for tuning...but I'm not 20 anymore and I don't want to take the chances that I used to. No question, it was a rush...just too much to lose these days.
Aside from that, it's just great to be back on my trusty 12R.

Thanks Dan. I'm going to try to make May, but it just depends on how much time I get to dial the bike in. No reason to show up at the track without a solid setup.
I sure wish I still had some trick wheels on the bike...but some other guy is sporting them on his silver 12R.

I like your old wheels! Thanks again for the deal.
Will you run a cut down tank on the 12 or is it gonna stay in street trim?
I found an extra tank thinking I'd make a LSR set-up but don't know yet, hate to swap back and forth since the 12 is my daily rider. I'm sure with my belly it would have to help. :-)

I'm not 100% sure about what I'm going to do with a tank. I have a spare A model tank here. I think I would benefit a lot from a cut tank, I'm just not sure how far away from "street trim" I want to get. I still would like to ride the bike on the road sometimes. Plus those cut tanks can be downright ugly.

Shane, I should be able to give you some pics of my 3/4 tank by the end of the wknd. I hate the look of half tanks, but I think this will be ok

Sweet bike Shane,
I hope Sal can do a little bit of his magic to my motor....He`s waiting for the pistons and cyl.`s to get back from Millenium for bore and re plate the cyl.`s....Once they are back he promises to install,hang the motor,RWT the motor,and flash the ECU.....Been 7 months,I`m ready..............

A few people have asked, "Just how fast were you going?". Well, based on the logger and GPS, 183+. I was pretty happy with that...sitting up, with no lowers, mirrors, 215 lb rider, 201 mph gearing, and rich tune. The whole point was to tune the bike...not run the best speed.
I'm sure that I can add 10+ mph to that at the "spot" now...if I want to roll the dice again.

quote:what's 201 gearing? 18/45?
18/45 would be roughly 201 mph gearing with a stock rev limit. My bike has a reflashed ecu, and spins over 12k rpm actual, which gives me a little more latitude.

quote:Gotcha. So what gearing you running?
Right now the bike has 17/47 on it. That is enough gear to run north of 190 mph with my setup. 17/45 is what I had on it before. I never took it over 11800 rpm that day, in any gear.

Curious if you do not mind me asking, what did you reflash your RPM to? I do not know if Zx-12's have a soft cut or a hard cut. If soft cut, were you able to reflash to a hard cut?

Sal did the reflash; he would know the specifics of "how" the limiter is set up.
I asked him to give me a little extra rpm cushion so that I would have less of a chance of hitting the limiter if spraying and/or right at the traps. It should cut around 12200 rpm, but I have not tested it in practice yet.
I'm sure that the motor could spin higher safely, but honestly I am happy with shifting at 12k rpm actual on a big bore street motor. It takes a bit of getting used to, seeing the tach spin to 12500 indicated!
