Great progress!

Looks like you have a later oil filter cover. Yours should be a round cover I believe (not sure exactly when the cutoff for the round cover was).

Also, the oil lines should be secured by bolts and a not screws.

Sam....... engine #581, you are probably correct. That oil filter cover was on the bike for many years. Note the large, aftermarket, 17 mm head locating bolt. I suspect it was “upgraded”. Any ideas were I might find an original? The screw are just to keep the crud out.

Original round oil filters are very hard to find. Many people take a later cover and turn it down on a lathe. Yamiya sells a replica. It is a bit beefier than the original:

If you get a that yamiya replica, i suggest turning it down on a lathe to match an original.

I believe this is where I got mine. It was nicely done. He’s probably sold out but who knows.

Checked balance on the total assembly. Heavy spot was a bit off the valve, so set the “yellow dot” there.
Will be nice to get the bike securely clamped to the lift table.

Rear wheel is next. Old bearings all came nicely, for a change!

Wonder what “4 6” means?

Looking good! Take video of you getting the motor in. I’m always curious to see how people do it!
