By say 1980 , dynos were pretty scarce.. big towns had them, but for many you had to travel to get to one.
And if it was a Harley tuner, he might not be so inclined or receptive...
And it could be expensive.
I remember when there was a show or event.. someone would bring a dyno, and folks would line up to use it..
Folks that dragraced...us... usually figured things out the other way... well some of us did.
