I got the 9er dyno tuned last night

I had never seen a dyno tune done in person before - it was pretty cool!

I didn't go there looking for big numbers (otherwise I'd trade the 919 in on a sport bike!)
I wanted smoother, more consistent fueling.

Getting the bike ready










I told him there was a spot starting around 4,500rpm where the power felt 'raw' instead of smooth, and asked if he could check the air/fuel ratio through the entire power range because I had a feeling it had some lean spots. Sure enough, the first run showed that it was rich down low and lean on top.
You can see where the blue line starts getting all wiggly just past 8,000 rpm, and the blue line across the bottom is weaving above and below the red dotted line, instead of staying parallel with it.



I only got a photo of the first pull. He did 6 pulls and made adjustments between each one. It's now a little smoother down low, and quite a bit smoother from 5,000-10,000rpm (the rev limiter kicked in at 10,200rpm).
I was happy, not only is the fueling adjusted properly and the power smoother, but as a bonus it picked up 3 hp in the middle and 1.5 on top, and gained 5 lb/ft of torque in the middle and 3 lb/ft on top.
Peak numbers are 105.16 hp and 66.17lb/ft of torque. Not too impressive compared to modern sport bikes but I'm happy with it!!


When I got there the guy was tuning a BMW S1000RR track bike. Performance-wise it was stock except for an Akropovic exhaust.






Here's his first run




Over 5 pulls and some fiddling on the laptop, he picked up 12hp in the middle and 10 on top, and he gained 8 ft/lbs of torque in the middle and 5 on top.
His peak numbers were 189.9hp and 81.5lb/ft of torque - pretty impressive for a bike that's almost completely stock!!

Good power out of your Hornet. I like your Yoshi's. The triangular set up fits very nice.

That's money right there.

That's damn near 10% gain in torque right where you use it.

Hopefully you can feel it, too.

Those are very good numbers, I don't care what anybody says. 66lbft of torque is kickass, and it's doing it at less than 10K.

If you don't mind sharing, how much did they charge for it? I have often thought of getting it done, but can't seem to find a reputable place around these parts and don't know what a reasonable rate is.

Do you also have a PCIII to go along with the Yosh cans? I too am interested in the cost if you don't mind sharing that.

190HP is what is claimed stock from BMW. Good God, what would you do on the street with that kind of power?

My '99 Superhawk put down 104.2 and 67.8 with Jardine slip ons and a ignition advancer. Two different kinds of power delivery, two different motors but almost identical peak numbers. Very interesting if not germane.

Get to your coffin faster than everybody else??

I would definitely want to work up to that. Maybe with a wimpy little 954rr or something with only 140-150HP. You know, a good starter bike

That blows my mind. I can't even begin to imagine twice the power as the 919, with even less weight.

seriously ... my stock 919 has enough power to get me in trouble... one thats tuned like the op's with a decent ammount more in the mid to top would get me in even more trouble..... but i cant imagine near 200 hp!

Those CF pipes lookin might sharp!!

Say, which shop did you take her to get tuned? Also, what'd that set you back? I'm thinking of doing the same, but have heard of dyno tuners manipulating the machines to show incredible gains... these guys look pretty legit.

If you want some insights into Dynoing plus what to watch out for, check out the links in LordDuckHunters above post. There's a good paper that can easily be found, Dan Kyle wrote some of it, and LDH collaborated on it. It's a 2 Part paper. Dan did Part 1 - Dyno Chart Basics, while LDH did Part 2 - Dyno Tuning Basics. RC51.org Dyno Chart & Tuning Basics page. When I got my copy of it it came as being from RC51.org Dyno Chart & Tuning Basics page I just checked the www etc just preceding, click on it and it goes straight to the page.

Nice bike md.........but you must of lost a couple of hp because your lights on


I thought the bmw with 190hp would have had more torque than that, my little 919 beats it with 100ft-lbs of torque

I've only ridden it to work so far, so not many chances to get too much above 5000rpm, but it feels just a touch smoother up to that point. I'm just happy knowing that the A/F is now dialed in correctly.
I'm heading to the track next week and am interested to see how the smoother top end and extra mid feels on the track.

I paid $150 for the dyno tune, which is a lifetime fee. I can bring it back any time and he'll try to tune out any issues I may have.

Those that asked where the shop is, call Nels at 2 Wheel Dyno Works in Kirkland.

$150 with lifetime troubleshooting/tuning is a great deal. Going to have to give him a shout and do a couple of runs.

$150 lifetime? i believe at some point in your life, he's going to say you're living too long. (i think there will be more money spent with him...just a hunch.)

He brings the dyno to various track days and bike events, so he may be in your area sometime soon. He just had the dyno at Oregon Raceway Park all Labor day weekend. Call or e-mail him and see if he'll be at PIR or ORP again any time soon.

i wish i had connected the dots when i had my bike tuned several times by nels. stand up guy, just super busy and hard to get ahold of at times lol.

mdtoney i dont think your bike ##'s are too high. i had my bike on that exact same dyno and got around 100 hp and 64 ft lbs of torque. so your power output is pretty damn nice!

Pvster, you need to outline what exactly fixed your Cold Start issue.

I just hard-wired (soldered) my PCIII to remove the crappy crimp connections and that did NOTHING for the issue.

It has to reside solely within the PC3.
