engine ys 63

1 Attachment(s)

hello everybody
I recently bought from ebay a second hand YS 63 engine. When I opened the parcel and examined the engine, I realized that on the crankcase the code FZ-53 is printed.
I wonder if that engine is really a .63 or it is the more little .53!!
Can anyone help me with this doubt?

RE: engine ys 63

i think the crank thread on the 53 is 7 mm and the 63 is 8 mm
