Assembly starts soon. Some electrical work to finish.
Pretty picture of Perfection!Paul,
There are four oil return holes on each side that are 3mm ø.
There are no oil holes in the pin boss.
Here are some pictures. This is the Wossner 8523D200 102mm piston.
Yes, he's using the 8523D100 piston that is a millimeter oversize and gives a displacement of 666cc....'Sandstone' out of Chicago, I think, is running the Wossner.
