J.ellwanger:

looking at the textured side of the crankshaft?which goes from BDC to half way up one side, (crank would be towards the intake side) is that something that need to be taken care of,
 and while I'm on this, I had a bit of piston skirt break off, and fall off some where,
but the piece is no where to be found in the bottom end crank area,  and there's no damage on the crank, chunks of metal, scratches, except the odd textured spot.

Just for grins...
What bike is this?
On the broken skirt, if it's not in the bottom end then it blew the piece or pieces out the exhaust port.
Shake your pipe and muffler to make sure nothing is in there rattling around..
I'll let others answer the bit on your crank..
Don't want to steal all their glory  :-)

J.ellwanger:
this would be my
1989 KX125 that i got to ride for 1.5 months

 I had the idea of rinsing my exhaust, W/ carb cleaner and was gonna say that's what i did, but that seemed like an odd thing to do. but I might as well do it. :mrgreen:

and come on, leaving me on the edge of my seat for others to post, you were already here!!!  :cry:
  alright lets hear it!! whats up with the cross marks.

 untill my posts has a *NEW* posted to it, im back to figure out WHAT THE HELL you are doing to those pistons on USMC500. and to find my missing skirt

J.ellwanger:
also meant to ask about the connecting rod, play which way for movement is ok, and what is not ok

sandblaster:
How old is the crank?
Did you measure with a feeler gauge the clearance between the crank rod and the crank half?
If so, what was that number?
If not, get that number.
Also, did you rotate your crank around so that you could see the oiling slot at the bottom of the rod?
If so was there and obstructions or was it clean?
