I'm going to an event, it's mostly going to be Harleys, the shop specilaizes in 1/4 mile drag bikes, they have a dynojet. Should I have any concerns if I want to put my bike on their Dyno?

Is there specific tie down attachments areas on my frame that I need to suggest? What settings should I put the bike in? Assume KTRC OFF. What gear should the bike be in? Is there anything else that you guys can suggest, any thing at all would helpful & appreciated.

Traction off and in 5th gear. 193 hp stock, 223 with Guhl/Brock flash, more with exhaust & PCV.

My dyno operator uses two methods. For setting the PCV up I think he used third gear and looked at the mixture or CO content and the shape of the power curve. He used various throttle positions and revs to produce the fuel map. Afterwards he did a full-throttle pull by shifting into third gear, letting the revs drop right down, then holding it on 100% throttle he let it rev right up to the limiter, then into fourth, fifth and sixth changing up at the limiter each time.

Sounds like he was enjoying himself a bit too much by the end of the day.

Bob, I agree about tuning, I got the impression he is just going to "bike night" where they dyno the bikes. If they are tuning the ECU it will take some time to do the runs and cool off in between.

Oh, if that's the case what you said is most likely correct Ed, it will just be a run right through the rev' range in one gear to produce the power curve which will be printed.

I'm not going there for tuning. Brocks Street Map is currently what's loaded on my PCV.

It's just for kicks via an invite from a local performance shop that specilaizes in building, tuning 1/4 mile V-twin drag bikes.
It's probably obvious to most who owns this shop but if not 'healthy' tip? I'd keep any critisism constructive ;)

STRADALE,

Turn the key on.
Right handle bar: – push MODE button.
Left bar :– push TOP (arrow shape) button UP once.
On dash: under/right KTRC mode will change from 1 to OFF (flashing)
Press MODE button again OFF stays solid
Make run.

You must do this every time the bike is turned off. (You know this, others may not ;) )

30 psi in rear tire.

Bike temp should be less than 165 degrees on your pull. The H2's heat soak VERY quickly... by the 3rd pull, it will be done (dropping power).

The bike MUST be tied down - no exceptions. This is not easy. The H2 makes far too much power not to be strapped, dyno numbers will suffer otherwise and this can be dramatic.
On the left side, we use a soft tie through the swingarm brace. On the right, we use the pipe hanger, if it's in place. If not, a soft tie around frame/foot works best.

5th gear pulls ONLY - go to the rev limiter. It won't hurt anything - don't let the operator lay on the limiter. ( Do not run in 3rd, it's mathematically incorrect for the dyno, 5th is the closest to 1:1, that's what you want)

Hopefully the dyno has a brake, we pull in on the clutch at the end of the run and slow the drum down with the brake... why would anyone slow down a $30K bike with a $20K dyno? If not, limit your pulls.

Shell 89 is the prefered fuel (no ethanol blend) any higher octane will hurt power readings, so will ethanol blends.

Street map will be fine.

Have fun!

Brock

Thanks Brock, perfect. Appreciate it.

I agree with everything Brock said. If you have soft ties, take them with you to make sure they are used. If you don't own them, I would buy a pair for this reason alone. They will push the bike up onto the dyno and then they will adjust the bike to get the wheel centered on the rear roller. Then they will adjust the rear straps to hold the bike down, but not to ratchet it too tight. Try to get there early and make sure the bike is very cool when they pull it on the dyno. Unless there is a well tuned turbo Busa or turbo ZX14 there, you should win easily. Be sure to let us know next week.

STRADALE,

If you ride the bike to the event, even if it is allowed to cool down for an hour or two - you will still be 10+ HP down compared to a completely cool engine that sat overnight and pulls from 150 degrees the next morning etc. This is simply the nature of the beast. The H2 is the most heat-sensitive machine we have ever tested. Between the heating of the cylinder head/engine/supercharger and the mass of the plenum casting etc... once it's hot, it's hard to get rid of it. We calculate @2% power loss for each 10 degrees the inlet temp rises - if you start with a warm plenum in a boosted application that heats the air as it builds pressure, you simply have to live with the results. The good news is that 10-20 hp doesn't matter, when you have a pile of them :)

That said, some guys get REALLY caught up on the absolute numbers... and the H2 will set you straight in a hurry if you skip details.

Thank you gentlemen, great advise. I have those really plush 2" tie down extensions straps that Ill bring. I just found on maps a Shell station by me, just don't know if it carries fuel without ethanol, if they do that would be a huge win all around since I'm always battling time w/ my small engines, snow blower, chainsaw, leaf blower etc and ethanol. Even one of my Harleys is carbureted. Always use stabil, never thought about trying to find ethanol free fuel especially in our nanny state, don't think it's available but I'm definitely going to look later today.

O/T a bit but re: temps - It's getting cold in NY, riding tonight to an event w/ temps looking in the 40Fs. I'm very familiar w/ how different high performance car/SUV tires perform, have 2 different, full sets of wheels & tires for vehicles that I use for the winter not just because of snow but because of the performance/safety w/ different tire compounds...I know the RS10 is a performance street/track tire, I'm very careful about warming them up before getting on the gas or leaning the bike over but are certain temperatures just not safe period?

2nd question - When you start your bikes cold believe the manual only states to let it idle a few minutes. What I usually do if in no hurry is let it climb a bit but at minimum I wait till the temperature readout goes from showing _ _ to actual #s , what about you? 165F max. if possible, thanks. I probably won't have to worry about this since I'm riding to the Dyno event & the temps climb quickly but if the bike is sitting long enough and it's cold enough outside, is there also a minimum temp. I should have before a dyno pull?

Tires will be fine as long as you are gentle as they warm up.

We start most pulls around 155. In theory, it should be higher (wait for thermostat to open) but the H2 produces so much heat, it opens very quickly and if you wait, it can hamper your results. I really can't emphasize how quickly this bike makes heat and how much it affects power. We have done this with all of our H2's, and they haul ass :D

FYI. We started a couple of our Ohio mile runs at 140 to keep the finish line temps in check.

Best laid plans. Had a full tank when I read Brocks advise about the 89 Shell. Today when I go out to ride Fuel light comes on so ok great, I have 0.9 gallons left. I set the gallon used indicator, locate where a Shell station is and run an errand. I use .3 gallons so heading home should be perfect, just get in the throttle, use a little more gas on the way home and it will be perfect. Just as it hits .8 wah,wah,wah, FAIL! lol! Pushed her the rest of the way, about a half mile while thinking of calling Shell for a commercial maybe called "total dumbass wants our fuel so bad he'll push his $30k motorcycle to get it". I know, I know having bit of 93 in there too wouldn't have made any bit of difference but that's the down fall of OCD. Anyway posting this not that anyone would attempt it but remember it's probably more like 0.8 not 0.9 for reserve hehee!

I just looked at my Pure Gas app on my phone and it did not show any ethanol free stations on Long Island. Good luck.

Thanks for that NOW, Ed. Just kidding but question since you're right, it contains ethanol is 89 Shell any better vs. 93 or is it only the 89 Shell no ethanol which makes slightly more power?
