Sorry for our smartass-ness, go ahead and do it and report back! Of course they're not tuning it but you have a n idea of how it's running on the dyno. If they can give you the AFR readibg along with the HP it'll be even better. Have in mind if they're a HD dealer it might be running on the happy side since aircooled's throw much lower hp numbers and they tend to "compensate" for it. Anyways you have nothing to loose if they know what they're doing

Ask them for the AFR, HP and TQ numbers on your chart if they will do that for $25. Is it one of the HP contests?

I just spoke with them. Best of 3 runs with print out. I think its just bragging rights for hp.

There is only one big problem ........forecast is calling for rain.

Unfortunately, no. It was raining and 40 degrees. Hopefully they do discount dyno runs again.

You need to find a real tuner. I have had probably 10 dyno tunes on several bikes and everyone of them was run to rev limiter. I always watch the procedure.

There's a lot of difference between "Dyno tuning", "Dyno testing", and "Dyno Shootout".

Dyno testing: If you are unsure of your current tuning, you can get it tested on a dynomometer. They should give you a printout of HP and Torque on a scaled graph of RPM vs POWER. On that printout there should be a parallel graph to the RPM of the Air/Fuel ratio. Most times, there will be three successive full throttle "pulls" and each of them should be overlapping in three colors for the first, second, and third pull. If your engine is too lean, the Air/Fuel graph will rise above 13.5:1. If your engine is too rich, it will fall below 12.5:1. THESE NUMBERS THAT I GIVE ARE MERELY GENERAL PARAMETERS AND MAY BE EXCEEDED TO YOUR OWN COMFORT LEVEL. You might also ask the operator to test your A/F at various cruising rpms. Just because it looks good at WOT doesn't mean it runs good at partial throttle or vice-versa.

Dyno tuning: multiple testing and adjusting to perfect tuning in all conditions.

Dyno shootout: ego.

No, that part's right. Below 12.5:1 is too rich. I fixed it.

But thanks for pointing it out. It was late. My bad.
