There is a new version that does have holes to help with lubrication.

  Thanks,

    The crank and crank ring.  (I changed the crankshaft front, rear, and cam bearings, but that was due to normal wear and an abnormal crash) My carb appears to be the large bore model, but I don't have anything to compare it to. Both my FZ carbs look the same. The carb and crankcase part numbers on the L and FZ are different, but that is because of the additional mount points for the YS soft mount on the carb and some chrome-like tape around the front bearing housing for the nose ring on the crankcase.

    I also drilled 5 holes with a #59 number bit through the crown of the piston into the ring groove, AKA "gas port mod". I did this to my other FZ with no other changes and gained 350 RPM. I used the head bolt holes to mark the top of the piston before removing it, then drilled the holes perpendicular to the chamfer on the crown. The resulting holes end up going at an angle into the backside of the ring groove.

    I probably won't be able to try out the motor for a few days, stay tuned.

        The newborn FZ to L conversion is ready to bench run. The crank ring and camshaft bearing installation was fairly easy with the tips from the list. Thanks to everyone who responded.
