Cleaning before top end “refresh”.  Aargh.....

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.

[Sam]

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.

Thanks Sam..... there will be a Yamiya order at one point. I’ll send you a request for the correct O.D. then.

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

Wayne..... Thank you. I will enquire. J.

Wayne.... He had one left! Got it. Thanks.

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.

Some progress today.

[BenelliSEI]

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

Wonder what “4 6” means?

Some progress today.

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