RE: How long should a DYNO take?
No I don't concur. A dyno run should take about as long as it takes to run it through the gears. I'll give them 10 minutes to hook everything up, and another 10 to unhook it. Well under a half hour for sure. Course a lot of the people I've seen working at these dealerships look to be graduates of " I rode the short bus high school", so what can you expect?

RE: How long should a DYNO take?
Well I build injectors for an NHRA funny car team, and on the "injector dyno" we can spend 20 hours on the dyno just with the injector working with different setups of fuel,and air mix.
You have to take into account they can not dyno a cold engine,and when they "dyno tune" an engine all are not the same some tweaks could take an hour or 2, that being said ,at 4 hours you better have the most fuel economy, and power you can get ,or take it back,and make them do it until you are satisfied

What you describe is how I envision it to go. I don't mind spending the money if they take their time and do it right. I just don't want to get suckered into spending a lot for little in return, which it seems is common practice for Harley dealers. Thanks for the advice.

RE: How long should a DYNO take?
If your talkin a dyno run to simply record the stats of your current tune then a half an hour is the most it should require. But a dyno tune to remap your ecm can very from 4 to 6 hours. Figure on the high side of that if your running a SERT since a shut down and restart is required for each change. The pcIII can be adjusted on the fly.

RE: How long should a DYNO take?
To say it takes 4 hrs,look into that.It all depends on what goes on what you are looking for.You want just numbers,very short time.You want more power,depends how they give it to you.Parts changing etc. always takes more time.

If you have a carb bike, they can also mess with combos on that, timing, etc. for hours.

Yeah, there is a difference between a dyno run and a dyno tune.
