On the older twin cams 88 we our use to seeing 2.5/3 thou run out.
The picture is a new St.Glide with 600 miles on with 6.7 thou this is nuts what the factory is letting go..... they except up to 12 now WOW....
We get two measurements on the front of the shaft and on towards middle to rear. Make sure you clean the shaft very well. Before you check.
And use a good dial thats has not been dropped. LOL.
Here is example.
But its a great idea if you are that far into it and the bike has many miles on it.
That it would not hurt to have some rebuild and fix.
Also here is a pic of Feulings crankshaft runout checker if you want something easy to use.
