i knew they wouldnt tune the bike, but for $25 i figured id give it a run just to see what the numbers show.
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
American Eagle HD in Corinth is having dyno runs for $25 on monday as part of thier New Years Eve events.
Is there anything I should do or change before a dyno run? Any pointers?
Does anyone want to meet and ride over there ?
I have to work Monday but there's word we may get off early, boss is a jerk and won't tell ya anything until ya hear "let's go" what time are they doing it till ya know? I could try to call ya as soon as I get off if it's not too late
Yeah listen to him. Because when they do a real dyno tune that costs $300+, they totally don't rev it to redline or anything. They just baby it and don't make any pulls that get close to where the real power is so it doesn't tax that Revo very hard at all.
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.
Everything is JMHO. Accuracy is not assured.

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.
