Feedback on Baseline Dyno for 2012 Street Glide
I'm not sure what a baseline dyno for a 2012 Street Glide should look like. I just got it back from the dealer after the 1000 mi maintenance. I had them do a baseline dyno. I'm in Denver, CO at an altitude of 5,300 ft so I expect it to be a little low. I'm also particularly interested in the Air/Fuel line at the bottom. I didn't think it should ever be higher that around 14.6.
I have plans for exhaust, A/C and maybe a cam and of course a tune. I would just like to know if the dyno is normal for a stock bike at this altitude.
Thanks Guys.

When the 96" first came out I averaged six reports from the magazines. It was
66/80. Yours is a 103" which really isn't that much different than the 96 so I'd say your in the ballpark.
I believe the dyno should adjust for altitude, humidity, etc.

Thanks for the feedback guys. I'm always a little paranoid about things like this. I saw the high air/fuel ratio too and just want to make sure it's not unusually high for a stock bike. I do plan to do exhaust, A/C, maybe a cam and a tune. I want to get it running the way it should be running. I just want to make sure the A/F ratio isn't too high and damaging the engine before I make the mods. I don't want to worry about riding it (did I mention my unnatural paranoia).

I think someone (maybe a sponsor here) did a dyno on a stock 103" and came up with about 71-72 H.P. and 85-86 ft-lbs torque. At the time I had a 2010 S.G. with a 96" that had Stage 1 and a V&H Pro Pipe that dynoed at 72 and 85. I thought, great, my 96" is as strong as a stock 103''.
For what it's worth.

Just a follow up on this thread. Mtclassic pointed out in another thread that "if that baseline was done with stock pipes and cat still in place you can disregard the afr as no way to actually read it unless they drilled your headers close to the ports. if they stuck the sniffer in the tail pipe it is not going to be close to accurate and will show false lean."
