If said individual's mother actually wears combat boots this would merely be a statement of fact and not a rude remark.

With sufficient prompting, I can do better....

Consider yourself prompted!

It is memorial day too

That's my point, most patriotic Moms would naturally be in combat boots today!

Sorry, you're not worthy...

He does use an older dyno I realize- with him, it's not because he is trying to sell people on higher numbers- he runs a home based shop, and probably bought his dyno many years ago, and since it still works....well, he's a "if it ain't broke, don't fix it" type of guy.

I had a dyno run a couple years back at another place (Dynotunes in Burlington), who uses Winpep 7, and the numbers there were within a couple hp/tq of the run I did at Don's a few months later. So by that logic, his dyno would seem to be in-line with, at least that other places dyno.

Maybe one day I'll run it on another dyno somewhere, but I'm not here to brag about numbers anyhow, and I honestly don't care if nobody believes them- the point of this thread is to share my experiences dealing with this guy, and to express how I feel about the end result of how the bike runs and performs. I know this is beneficial for anybody around here that is considering doing a build, and is looking for a reputable, honest, and knowledgable local builder/tuner.

The other point of it is to plant a seed of thought that as unconventional as it sounds, maybe, just maybe, this guy has something when it comes to these 110's- like I've said, this guy is a lifelong racer and harley engine builder who has done 39 of these 110 builds. When the 110 first came out, he found that it wasn't performing the way it should by way of traditional performance mod's. He did extensive flow bench testing, and came up with his combo that creates the optimum intake/exhaust flow...he says the valve(s) are too big as they come, so whatever he does optimizes the flow and velocity, etc. This, combined with his tuning knowledge, gets the results he gets.

I know I'm not explaining all of what he does properly, because it's not what I do for a living, and the technical stuff he talks about is over my head. But, if any of this piques the curiousity of any of the pro engine builders on this site, I'd say feel free to give the guy a call, and see what you think. Don Morris- 905-679-2237.

Oh yeah, that's right- a US holiday today. Happy Memorial Day!!

This was an old dyno run of mine on a Winpep 7

Funny when my girls were growing up, they more than once heard that "your mom wears combat boots".  For course they replied she sure does, to work every day. 

She is a 20 year Navy Vet, as am I

NorthStar,

While it may seem that they produce similiar numbers they don't, the difference is in the Correction Factor.  Note the barometer is close but not exact, and i didn't do any real rounding on the numbers just to give the examples so they would make sense based on the numbers in the sheets.   The runs on the dynojet are 1.02 the correction factor on the dyno he did for your bike are 1.12 and 1.15.   If you take 10% off your 118 number you get 107 HP.   Take 135 and that is 125 torque.  

1.12 (approx 10%) change =  about 107 hp and 125 torque
1.15 (approx 13%) change = about 104 hp and 119 torque.

1.02 correction factor from the dynojet.

You know.... if you get on that scooter and ride it and you end up with  smile on your face.......then who gives a chit about numbers

There is a builder on here that just moved his shop and is very disappointed with the lower numbers his dyno is showing at his new location......elevation, humidity, baro pressure, temp....they all play a role in the numbers game. In the end it is...ARE YOU HAPPY

Good answer

[North Star]

And I agree with that. I didn't headline with the dyno numbers- I posted the charts, and the numbers are on the charts, but the point of the charts is to show the curves, and the improvement in the curves from the baseline to final run.

I'm happy with the bike, and the mod's he did. I'll have an even better impression once I get some real riding time in- so far this year, I've ridden the bike to Don's in mid-April, picked it up last week, rode it for about an hour and a half yesterday, then had to drop it off at another shop because Don pointed out the compensator sounded bad, plus my trans shift lever which was getting loose last year, was getting real bad.

Dropped parts off today to the other shop, and had a look at the compensator- this is the SE compensator that I replaced 13,000 miles ago, and it has wear marks on the inside (hub?) area. Don't know how it got like that, but I think I recall reading that the SE compensator had known issues. Oh well, at least the inner primary is off for the trans lever, so at least the timing is good.

Picking it up Thursday, and other than a new rear tire, I hope that's all the shop time it requires this year. Oh ya, plus once I get the OEM headpipe I bought, I'll have it ceramic coated, put on, and touch up tuned, THEN that's all I hope.

  Ride the dam thing, have fun and let it go. You can't convince everyone and maybe no one, so unless your going  to post your dyno sheet to your windshield, who cares. Good Job.

[North Star]

I have let it go- I thought I pretty much indicated that in my last couple posts. 

Btw, my mechanic updated me on why my compensator wore out so quick- the wrenches at the shop I used to go to installed the springs backwards!
