50mm Tak has an 88mm rod, and leaves most pistons 2mm in the hole. At least the 5-6 I've had my hands on. 54mm cranks have had 94mm rod, same as a stock Honda. We've had to cut the base of the jug on all of them.

50mm stroke/25mm throw is 4.25 or so more than stock. A 6mm shorter rod leaves it -1.75ish. When I rebuild them, I've used a 6v Honda or XR80 91mm rod, that leaves the piston at +1.25 or so.

54mm stroke/27mm throw is 6.25 more than stock. Add a stock length rod, and you're needing a 69mm jug and should be at deck or above.
