Dyno Run
Had a freebie at the HD shop so I did the Dyno run.
08 1200c , stage one, V&H slip ons and Fuel MAP download. Lower than expected numbers. 68hp and 69.4ft-lbs torque. How much is lost through drive train? Factory specs say 79 ft-lbs at the crank on stock engine. |

Re: Dyno Run
Appears factory hp at the wheel is about 59-60 and torque is about 62 63 .
So about 10% increase. Wonder if the Thunder max Fuel system would improve these any along with making it run a little cooler. |

Re: Dyno Run
Forgot to mention that the Fuel/Air ratio was 17.4.
Guessing a richer mixture will cool the thing some. What do you others run yours at? |

Re: Dyno Run
No the dyno sheet showed 17.4. Same dealer did the upgrades when the bike was new. Bike has 11500 miles on it now.

Re: Dyno Run
if its that lean - either the dyno needs calibrating or if its correct then you need a fueler, normal afr should be 14.6/14.7 from the factory on full stock settings.
i would see if you can get another run on a different dyno just to confirm that AFR

Re: Dyno Run
I took my 99 1200 S and had a dyno pull last Friday. It has V&H staggered shots, SE air cleaner and a thunderslide and rejeting done by me. It has 29,500 miles on it. It made 67.3 HP and 68.4 torque. I was pleased with that and am going to tinker with my jetting some and go again in a few weeks.
