Colonel's 124" dyno sheets!

[Colonel Sanders]

Picked the bike up this afternoon and rode it until dark (only to discover that my headlight went out!) Man was it ever worth the wait! This engine reminds my so much of the 98" I had before except with alot more balls! What I mean is that it has the same excellent drivability and general driving characteristics. The power delivery feels of the same shape....only MUCH bigger. It's just as smooth. No extra vibration, shakes, or sounds. It's like my baby 98" is all grown up!

What can I say, I couldn't be more pleased with the drivability, the sound, and of course the power.

As a side note (and VERY unexpected), this thing cranks fine without the compression releases. Not that I'm going to make a habit of it. I just had to know. When it was cold it spun over just like the 98". When it was hot it did spin over slowly but it still fired up right away. I know that's pressing my luck so don't start preachin'. I used the releases after that...well, at least one of them. It just doesn't seem to need them both. Remember, the CCP of this moderate build is only 183 lbs calculated at sea level.

I beat the snot out of this thing off and on for the first 50 miles and I couldn't get the temperature over about 250-260 even when trying. The weather was nice. About 80-82 degrees and very humid I'd guess.

On to the charts. I don't know if these were the final charts that Michael made. He was gone for the day when I got there so I didn't get to ask. I know he had said that he was going to try different plugs and maybe tweak the timing some more so I don't know for sure. Regardless, I'm just over the results so far. I was told by the service manager that this bike now holds their dyno's HP record. The previous best was 135 HP on a more aggressive 124" build.

These were air cleaner on, baffles out (the way I intend to drive it. It's really not that loud with them out and sounds awesome!)

The charts both compare my 98" numbers to the new build.

BTW, I'd like to give aHUGE thanks to both Steve at GMR Performance and Michael at H-D Montgomery. Steve, you put up with my 1001 questions and guided me safely once again to the perfect fit for my needs. You always make putting together the perfect package a pleasant experience and take away alot of the stress that comes with really wanting to get a build juuuuust right! Michael (I don't know if he reads here), you got it together quickly once again and everything seems to be RIGHT! Thanks guys!

congrats. be careful on that thing, PAPA!

Actually Dennis, I'm headed to the hospital in about 10 minutes!!! My wife is already there and she's dialated 2.5cm and counting. Looks like we'll have another girl sometime tomorrow!!!!!!!!! Wow! WHAT A DAY!!!?

It's gonna be a looooooooooooong night!!! Gonna need some

Congrats on the build Colonel, just as you ordered. Now it's time for diaper duty once again, enjoy and congrats to you and your wife.

[TXCHOP]

Congrats Colonel!!!! Being honest the curves suprize me. In a good way though. Those pipes i guess proved themselves again to be a conteneder as well. You will enjoy that power for a long time.

Now stay off the bike an take care of the new kid will ya.....

Congrats on both accounts!!!!!!

Just think of all the new polishing rags you will have. Just make sure you pick from the clean pile.

Congrats also.

CONGRATS on everything!!!

False alarm on the baby. She was slowly going into labor but they gave her some kind of shots to hold her off for a little while longer if the baby wasn't ready (said the shots wouldn't work if the baby wasn't ready) and so I guess she wasn't ready. But, it won't be long! They said they really doubt she'll make it another week.

Anyway, today I modified my Hi-Five air cleaner to work with the CV51 filter. Looks great! Very happy about that.

I'm going to look into a leaner needle for the CV51. We have the leanest one HD has and it's still pretty fat between 2300-4200 RPM. I know there's some more power to be had there. I also think it's a bit too lean from 5300 on up. It's at 14:1 at the HP peak. Add some fuel and bump the timing a little more and there might be another pony or two hiding in there.

Any ideas on the jetting? Thanks!

First, congrats on a nice build!

I would not mess with the afr..... in a nutshell, you throw fuel at them to peak the torque and then you lean them out a little bit to peak the hp. Looks like they have it in the ballpark to me and your torque and hp cirves look pretty smooth to me.

[Dyna_Willie]

WOW! Very impressive! I would say it was well worth the wait! Be careful, congrats on the new build, congrats on the new baby girl that is soon to arrive!

[FXDRYDR]

Looks great Colonel! I'm eyeing a similar build and really appreciate all your reports on progress. Looks like it's been well worth it!!

"I would not mess with the afr..... in a nutshell, you throw fuel at them to peak the torque and then you lean them out a little bit to peak the hp."

Thanks Tote. You know I respect your knowledge on this. Do you think that there is perhaps just a bit too much fuel being thrown at it from 3300-4000? It looks like it's at 11:5 for most of that span. The 2800-4000 range is very important to me. That's probably where most WOT time is spent if you think about it.

How much power could I be losing with a 14:1 ratio up top? I'm thinking not much but I'd like to hear it from you.

One last question for you, Tote. I know the Dyno differentiates from real life in that it is unloaded....in what ways is the air/fuel curve different on the road at WOT in say 3-4th gear than on the dyno. In other words, does the fat spot from 3300-4000 get fatter or leaner when loaded? What about the lean spot above 5300? I'd hate to think that it's even leaner than that on the road.

[HDWRENCH]

You are welcome, Glad that you are happy. Power looks good and I have said this before and will say it again. Those pipes keep you suprised. I would have thought where where going to come up short on the numbers. Would be great to see what it does once you get some miles on it , and the re check it to see the numbers are once loosened up some. The AFR is not that bad really, you could tweak it some here and there, but the gains may not be much or any. Main thing is drivablity, smooth down low under light throttle?? pulls nicely under load. JUST RIDE IT!!!!!
