You can thank Suzuki for starting that trend and BMW for making it popular !!.

Alright, it's been a very busy past couple of weeks, but last Friday we finally wrapped up testing on the NC700X! Still finalizing a few things before bring the kit to market. This bike had some interesting fueling characteristics; in most ranges it ran lean, as expected. But once it got above 80% throttle it starts to absolutely dump fuel into the cylinders. So in the top end I took fuel away to get power, and in the low and mid ranges I added fuel to get power. I know some of you were hoping I'd get 10hp out of this bike, but that would have been an astronomical 25% increase in power, which is almost unheard of for gains from just fuel tuning. However we did get a 4.6% gain in power and 2.3% gain in torque. This is a fairly standard increase. A 600cc sport bike making 100hp stock will get anywhere from 4-5hp from fuel tuning alone. On the dyno graph posted below you'll see two 100% throttle runs (Bazzaz Map vs Stock Map) and two 50% runs. Because the power map I made did add so much fuel to the cruising ranges, about 25%, I made a second map that only has the fuel modification to the top end, where it's taking fuel out of the stock map. This way if you're just cruising on the highway you can still get your standard fuel millage. But seeing how it was running anywhere between 14.5:1 and 15.5:1 I did not attempt to tune it any leaner.

Here's the dyno chart:

That's interesting work. I'm not trying to dog what you've done but I do have a question. Does a 4.6% and 2.3% gain in power and torque, respectively, produce a felt increase in performance to the average rider?
Thanks,
Mike

+10 on the above^^^^^^^^^^^^^^^^^^^^thinking the same thing

Appears..........Not much reward for the risk and cost. Plus those # are with a slip on exhaust which adds more costs.

I don't ride a nc 700 myself.

Out of curiousity; I get that you've added fuel in the lower revs to gain more power there, but apparently the stock map has 'too much' fuel in the upper revs for decent combustion so you actually had to remove fuel?

I assume that has to do with some kind of emmisions, or maybe to make sure the engine wouldn't make more than 47 bhp and still have some revs left.

Since you deleted fuel in the upper rev range to gain power, does the bike actually uses less fuel when going WFO with your map?

I have a CBR250R myself, considering your fuel controller. Could you give a somewhat same kind of explanation of the 250 as you did with the NC 700? I'm interested in a bit more power but not when the fuel consumption lowers.

Was this a DCT model or manual transmission?

I brought my bike home today
I put 1 whole mile on it and installed the Hepco Becker skidplate.



I can't wait for some better weather.

HP/Torque

When I look at the dynamotor charts posted, my interest is in the reading from 5,000 rpm's down. Looking at these values I have to say Honda did a good job with the FI. Like Honda say's it's a "NC", New Concept.

Dave, I didn't think you could dyno a DCT because the front wheel has to be turning in order to shift. Not sure, but I thought I heard that somewhere.

It's an awful cellphone pic, but at least it shows the sold sign!



I've joined the ranks of NC700x riders. Now, if the snow would just stop long enough to let the salt slide off the roads .

Where did you purchase yours? I bought mine at Sport Mann in E.Syracuse... Joe (the owner) was a great guy to work with,and the service department was excellent in installing the accessories & the first service.

Welcome to the rank and file!

Well it's 40 and raining out, might as well go for a ride.
Holy shit this bike is sweet. I only rode 20 miles but it was great.
I never hit the mythical rev limiter like other people had reported.
Who does 30 MPH in a parking lot anyways
Compared to my DRZ this thing rides like a dream.
And on the way home I stopped at Jimmy Johns for a sub and the gas station for some snacks. The "frunk" held my sub, a bag of chips, beer, and a 2 liter of Pepsi with room to spare.

Panniers

Finally went and ordered Givi panniers, went with the E21's, like the top loading and with the funk and tank bag, did not go for the top case. I don't like weight that far back anyway. the panniers and mounts came to $406.80, delivered. Now ready for summer.

Anyone heard of release dates for the 2013 models?
