Our local Harley dealer had a free dyno run for customers last weekend.  I have a 2007 SERK I bought pre-owned in 2008 with 1700 mikes.  Now has 18,000+  miles.  Bike had SERT and unknown brand of pipes when I bought it.  I have not changed anything.  Had 110 recall done Feb 09.  Never had a problem with the bike and other than regular maintenance have not messed with the engine.  The numbers came in at 89.1 HP and 108.7 Ft. Lbs. Tq.  Wondering what anyones thoughts are?  They thought they could probably tune it a little better, but that was the whole point of the promotion.  It seems to run fine.

Couple thoughts.  First, since a stock 110 was good for about 80 hp and 95 ft-lb, your numbers look reasonable for a muffler change and SERT.  Second, if your dealer runs his "free dyno run" promotion like many of them do, that one run is not going to accurately reflect your true numbers.  The reason for that is that the bike (entire drivetrain) has to be up to full operating temps for accurate readings, and one run won't do the trick.  The reason some places do the one run promotion is to convince you your numbers are low and you need them to tune the bike.  Then, even if they do nothing at all they can show (after you pay for a tune) an improvement just by making several runs to get everything up to temp.  I'm not saying that is the case with your dealer, but just letting you know that the scams are out there.

Dyno numbers aren't terribly important in the overall scheme of things.  Are you satisfied with how the bike runs considering how you ride?  If the bike meets your needs and makes you happy, save your money.  Once you start on the "more power" trail, it can become a slippery slope indeed.

Thanks Jerry, probably great advice.  With all the bad I have read about the early 110's my bike has been great.  Has never given me the first problem, never a fluid leak etc. Quit running one time due to loose battery cable.   My friend has a 2007 SEUC he has owned since new with about 20,000 miles with similar results.  Plan to continue to enjoy the bike the way it is.

I think they need to start an "ask grc thread". You may not always agree with his answers but you have to appreciate his insight.

[dlaws01]

Those numbers look fine to me.

Bone stock my 2011 FLHTCUSE6 dyno'd at 81 HP 95 TQ.  Your numbers seem reasonable

10% gain from a pipe n tune, the cheapest power you will see on these geezers...the inverse curve starts here...

as Black Diamond pointed out to me..."You can't ride a dyno sheet!"

Every time you open the throttle, you ARE riding the dyno sheet. If you are the blue lines and your friend is the red lines, how do you reckon it's gonna play out?

[miker]

How much does the guy n red weigh versus the guy in blue?   

[RedDevil]

... If you are the blue lines and your friend is the red lines, how do you reckon it's gonna play out?

who cares?   Unless you are racing, you're just chasing numbers.  All that really matters is how it feels when you ride it.

All that really matters is how it feels when you ride it.

The graphs are the same bike. The only change was the airbox. If someone showed you those 2 graphs and asked you to pick which airbox you wanted, would you say "It doesn't matter, you can't ride a dyno sheet"?

[miker]

Torque tube airbox?
