Panhead Evolution . . .

Chris' '63 outside oiler pan was runnin' Evo pinion roller set-up . . . Hmmmm?  Learn something new everyday.  As far as rods go - the crankpin measured -.0005 under(maybe worn a bit) but straight.  His rods were 1.6265 (thou & a half oversize) It had +.0006 over rollers (a bit loose - that's what was in it).
I could slightly hone the races to square them up and go with +.001 over, which is probably what I'll do. Remember, we still need .001 clearance in there somewhere.  Hey, mathematics was not my strongest subject - I only went to intermediate algebra and hung it up.

You could shoot for a healthy dose of "noticeable shake" like the flat head service manual call for! Lol!

Understand it but would never attempt it, that's why why God gave us blokes like you guys . . .
