I recently started$ breaking* these bike down and rebuilding as a hobby. The first bike I ever built was my 06 electra glide. Last night I went to get on and knock knock knock. i thought for sure it was blown but tearing into it the witness marks are in jugs and camshaft. used a 590 cam with Tmann performance heads. I’ve got witness marks on the jugs ever so slight and bad witness marks on these cams. So it’s in bad shape after few thousand miles. It shouldn’t look like this after this long. What is your guys opinion. You can clearly see the cylinder studs. Why?
Here take a look tell me your opinions.

First thing that comes to mind is over heating/lubrication issue. Maybe piston/cylinder clearances too tight ?
