For a thorough tune, how many miles are usually logged on the dyno? Mine showed 20 miles.

That's like askng how long a kite string is. Lots of variables, depends on how much time the tuner actually spent going through each gear through the rpm range and tuning front and rear cylinder. Vs loading a close map on file and doing a few pulls and calling it good. I'm not a tuner and don't know how to tune, but it seems hard to find good ones that spend the time to dial it in specific for your bike.

I think if you are paying the money the bike should be running at the top of its game, not lean in spots, smelling like fuel out the exhaust, soot building in pipe or popping. Maybe what I ask for is too much. 20 miles seems low. Did you check your odometer when you dropped it off and picked it up?

I always log my mileage when I drop my bike off for work.

I can tell you that I typically have around 50 miles by the time I am done tuning and that's if no issues are found. If you do not have a base calibration that is close then it goes up from there.

I can give an average of a little ore a half a tank on a routine build.  Never really paid attention to milage.  I have had some customers notice milage.  Without knowing more details. 20 seems light.

Thanks guys, I asked because I wasn't present (dealer tune) and 20 seems light to me also. Previous tunes on another bike logged more miles and took at least 4 hrs, one took 7. Bike runs OK (80 miles since tune) but a little exhaust pop backing off in the lower gears. Going to put some miles on it see how mileage is etc.

Being a 4 gas guy and sampling one cylinder at a time, 20 miles seems way too little. I'd imagine that would be on the small side even for guys who can sample both simultaneously, even if the guy had a great library of starting map to choose from.

usually see between 40-55 miles or so if the guy actually cares and tunes and takes the bike for a ride maybe a few more

Depends on a lot of factors.
