This morning I scuffed down a few spots on the frame that need a bit of touch up before the engine goes back in place. Carefully ground down the right side, lower front engine mounting lug. Taking the lip off makes moving in the engine so much easier….. “Before” and “After” photos. The old grips are used to protect the frame.

When I grind down the engine mount, I try and remember to clean up the mount where the ground lug from the battery gets sandwiched between the engine and frame.

Engine is just about ready to go in. The clutch, alternator and gearbox covers have been vapour blasted. I think I’ll pull them off when the engine is installed and give them a real polish. The chrome cam cover is not perfect, but it will look fine once the engine is buried in the frame. The side covers should match.

If you look closely you might spot two bolts (both grade 8 hardware, 3/8” and 7/16” X about 6” long). They are covered with old heater hose. Since both these right side engine mounts bolt in after the engine is in the cradle, I use these as “handles” for this side of the engine.

Waiting for a full set of Yamiya Engine Cover screws. They should be here in the next few days. I want them in the cam cover, before engine goes in. Polished two more tappet covers, four to go. They are a pain!

Good tips John,  Grinding the engine mount, I did this on the 750, and recently did this on the 550.

I need to grind the ground area and use bolts like this for handles, I like that..

Your CB750 engine looks beautiful  John.

Thanks! Dwayne did a nice job! I’ve got a nice points cover too. Just waiting for a screw set from Yamiya.

Any good simple lifting device for the engine into frame or sheer muscle force and damaged spine?
Without C hook and crane...

Per…. The three young mechanics that work for Tim (the fellow that I race with) come by all the time with their carburetors for rebuilding (they all have older dirt bikes and snow machines). When the time comes, I invite them over “for a beer” after work. I get everything ready, wrap the frame in old bar grips and pipe insulation, and they put it in in about 10 seconds. All I do is slide in the two bottom bolts!

A good setup without tools that will take too much space!

I use the lay down method.

That makes the most sense but I never manage to do things in that order…….

[Floshenbarnical]

I use the lay down method.

I'll be doing this in a couple weeks. Seems like it should be a piece of cake with a naked frame.

I abandoned my commitment to cut the frame for a frame kit because the only frame kit I can find right now is Carpy's, and I don't like it. It would be sweet if someone on here was interested in fabbing another weldless kit for me, but I'll limp on without it.

He has done Franks weldless for a while.

I’ve only ever cut one frame. I did use a weld in kit from “Carpy”. Never bought anything from him, but the bits came with a project I bought. Fortunately I have a friend who is an expert welder, and we were starting with a bare frame. I have to say it fit beautifully and to my mind the finished product is the soundest solution.

[BenelliSEI]

Real snow day here! Did all the frame touch up paint, prepped oil lines and started cleaning up engine mounting brackets and hardware. The oil hoses were looking sort of crappy, so while I had the black enamel paint open, mixed a bit with some thinners and “stained” the hoses. Turned out well. Finished up polishing tappet covers. Waiting for the cover screw set from Yamiya…….

I spoke w him end of November, he doesn't have any more.

The thing I don't like about Carpy's kit is that it gives no provision for the flat cross-supports joining the rails and the backbone, I would have to fabricate my own brackets for that and I don't need *one more* thing on the honey-do

You’re correct. This photo suggests he just leaves those flat bits out. We added two, non standard braces at either end. I don’t have any photos as the bike is long gone.

Japan Post is pretty amazing. My most recent Yamiya order took less time to get to Toronto than to get the rest of the way to my country address. Very impressive.

It’s not here yet, “out for delivery”.

10 minutes later there’s a knock on the door!

Wow, one week.

Is this for every cover on the engine?

Yes, appears to be complete. I did about 1/2 and they look great! I subbed in a cap screw on the front/ centre. Easier to install the cover when the engine is in the frame.

[BenelliSEI]

Cleaned up oil lines.

[BenelliSEI]

Ever notice one foot peg is further forward than the other? Spotted this while prepping engine mounts. Both pegs are rolled ahead on there pins, where they belong.

The big lift is next!
