Did five runs to check the numbers. No ink in the printer and only a photo of the screen. 107 H/P  118 Torque.  I think it has some good numbers. The second bike was a Dyna Glide 107(?) 37 H/P  52 Torque.  da prez |

Photos or it never happened!
:-D
Now seriously, any prep/mods work in the valkyrie?
107HP in the wheel is pretty good.

tweaked dyno jet dyno or operator goosed it at the right time to up the numbers. Stock valkyrie doesn't make that much. Even the '97 all the magazines used only did 101/101 on certified dynos. what type exhaust? |

Stock exhaust that has been opened up a little. The numbers are why we did five runs.

The HD numbers seem way low. Didn't the stock 88ci Harleys have HP in the 50s or 60s?

So did Dale dig out the dyno and git it uncovered or did someone else do That particular job. Providing I can get mine there again I would not mind doing a dyno run on mine! Git the pictures posted Brother! You KNOW how this group can be.  RIDE SAFE. |

I would love to ride your bike or any other Valk with those numbers. I dynoed mine once years ago and while acceptable, no where near those. My bike has been in the garage 3 years and will need a major “attic rat” type of tune up to be road worthy again

I'll try to post photos of the numbers. The owner said that was common for a HD. I do not know if it is in for engine work or what. He just wanted another bike to run. He did another after I left.
I know there is doubt , but I will try to prove the numbers.

with stock exhaust that dyno is tweaked to give higher numbers or the operator is cheating to make people feel good. only a mustang dyno with four gas exhaust analyzer can give true numbers. and that big ftlb number means u are too rich on the MJ. a stock valkyrie does not make those numbers. http://www.pencilgeek.org/2009/09/exposing-dyno-cheaters-how-the.htmlhttp://speedtalk.com/forum/viewtopic.php?f=1&t=23440 |

I had mine run on the dyno at the first Inzane in Paducah. It gave 97 hp/94 torque on a 100 degree day, recall how hot it was there that summer? I was happy with it, didn't really care what it put out I just wanted an idea of what it would do. Might be interesting to know what it might do on a cool rainy day.  |

Vaquero , there was no need to cheat and the owner ran the tests. The last time the dyno was checked , it was factory specs. I just wanted to have an idea. I have another Valk sitting in the garage. I'll try to have him run it to compare the numbers. It was run , as I said , five times as he did not believe the numbers when I looked them up. It was just a topic of interest.

this is the 103 and my 107 is higher,, Harley-Davidson Twin Cam (1688cc / 103” 45 degree single plug v-twin with F.I.) – 83hp & 95 ft lbs of torque Harley says the engines make 10% more torque than the previous versions, but the factory did not release horsepower numbers. According to the EPA release, though, the new 107 produces 92.53 horsepower (69kw) @ 5020 rpm, and the 114 produces 100.57 horsepower (75kw) @ 5020 rpm for the 114. https://ultimatemotorcycling.com/2016/08/23/harley-davidson-107-114-milwaukee-eight-to-replace-twin-cam/ |
