Thanks,

Ihncheol

  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.

     Please list all the parts you changed. I have a FZ I have tho't about
doing that to. Did you change the carb?
    Thanks

      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.
