I was at a Bike Show that had a Dyno on a trailer.  For $20 I had it tested.
Bike :  FLHTCUSE5
  FullSac x pipe with 2" baffles and the TTS Master tune from Steve.
Eddie the tester said that dyno was the most conservative of his company's dynos.
I don't know how many they have, or anything about them.
I will post the sheet. 
I was hoping for more HP (86)  Torque looks better at (106).
He said that the fuel air ratio is a little lean between 2600 rpm and 4800 rpm.
Steve will you take a look and tell me what you think?

What prompted him to make a comment like that?  I think I'd have kept my $20.

[strokerjlk]

That would be fine for a 4 th gear run. 86/106

[RedEagle]

Yes a 4th gear run.

It came up when he was strapping down the bike.  I said I guess the results vary from dyno to dyno. 
That's when he replied yes and this one is our most Conservative dyno.
I think it was worth it to get a base line.  I like the smooth curves without big dips.
I am thinking of replacing the cams with Steve's recommendation and he might have some comments on the tune for me when I add the cams and gaskets.

RedEagle,

Here's my 2011 CVO Street Glide Dyno with V & H True Duals and Hi-Output Slipons. It was a pretty hot day and fairly high humidty. Can't remember the gear for sure but I think 4th. My tuner never eluded to me the accuracy of the dyno outside of saying it was calibrated properly.

Considering that on any given day/an given dyno results will vary, I think your numbers are right in track with where these things run.

[strokerjlk]

That one looks like a a 6th gear pull to me

Spark count can/will tell what gear.

Talked to my tuner yesterday. He said that he does all 6-speed dynos in 5th and all 5-speed dynos in 4th.

The obvious answer is the dyno guy didn't want RedEagle to think something was wrong with his bike, since the numbers might be lower than expected.  No matter what the peak numbers, the dyno run still will show problems with tune, dips, AFR, etc.  $20 is a bargain for access to the expensive equipment, sophisticated technology, and useful info that results.

He didn't say the dyno was broke, just that it was "conservative".  Maybe "honest" would have been a better adjective.

If he is pulling the 5 spds in 4th, he is wrong, maybe, just maybe, a 65T rear pulley Evo, but that would be it.
Do they pull the Shovels, Iron, or early Evo XL's in 3rd??

 As long as you do all the wot pulls in the same gear.it really dosent matter,for that particular bike. Now go comparing one dyno sheet to another, the bike that is run 1:1 tranny ratio, 6th in a 6sp and 5th in a 5 sp.will make bigger numbers on paper,then one that is run in a lower gear.
comparing the two only adds to confusion.

[HILLSIDECYCLE.COM]

I agree with Jim.
You should not use the mechanical leverage of the gearbox, long or short.
1.1 should be where you want to tune.

Dynos are great tools for gathering information. If your doing full throttle pulls, your going to get AFR at 100% throttle only. And typicaly from one cylinder only
unless the tuner is lazy enough to sample from behind the collector thus reading mixed gasses from both cylinders. If your drag racing, full throttle AFR is very important. On a Touring bike, its the least important. Sampling AFR at idle, cruise and sustained high speed is very important. A cold engine will produce some of the lowest peak numbers you will ever see. You have oil in three holes that take time to heat up. Engine oil needs to be above 200 deg. 220-240 is best. Your chart shows Run#3. Three runs is not nearly enough to get things at normal operating temps to see the big numbers that everyone hopes for. AFR lines go all over the place as the engine gains heat and the ECM chases cylinder and intake temp readings as it calculates fuel delivery. AFR lines don't stabilize in three pulls.These rolling dyno centers are at these shows for one reason, to make money. Its always fun to see your bike hitting 6 grand as on lookers hold their ears. Point is, your not going to get a lot of usefull information in three pulls from a guy willing to strap your bike on the tray for 20 bucks. Its like the free brake inspection at Midas. It never ends with "your brakes are fine, have a nice day". I have to imagine, you know more about your tune than anybody else, your the one riding this bike. Does it run smooth, pull hard, start easy, get decent milage? If its not doing what a Touring bike should, please call me. If your Quarter mile times are a little off, we can talk about that too!

JMHO but doing full pulls is not the way to warm up a bike. Lock the brake at 2500 rpm, enough throttle in high gear to load the brake 25% until up to temp is much easier on the bike than just making full pulls. Then 3-5 pulls should take it to thermal loss. As for the OP I think your numbers look close to where they should be. With an SAE of 1.22 you must be close to 5000' so you are probably not running in the 100 kpa area's of your map.

I agree. For me, the full pulls happen after the VTune sessions are over. Even then, they seem to peak after 6-7 runs.

Yes, YES, Yes, 43mpg on mountain touring I think that is good!
I have no problems with the performance.  In Fact I love the way it runs and sounds since I did the FullSac conversion!
I figured since I got it dynoed I might as well have someone look at it that knows what they are looking at.
Thank You Steve and Lone Wolf

That's what's most important.....that you're happy with the way it runs!
