Honda-SOHC

I'm curious whether anyone here has my old blue 750 K2. I bought it new from Reads of Leytonstone in 1973, fitted with their own clip ons and rear sets. I sold it in early 1986 and from gov.uk tax was due 1 October 86. V5C issued 7 Jan 2016 and now listed as red.
I only have two very poor polaroids (remember them?) of it. Can't remember taping the grips up and no idea why I even did.

Despite stating in my new member intro thread that I was looking for a 750 to restore, I’ve ended up getting a CB350F (American import) instead. There was a post about it on this forum

Its obviously been stood for a long time and there’s a lot of surface rust but everything is solid. The tank has a couple of shallow dents but looks good internally. The mudguards have fine pitting but are free of dents and should be ok for stripping and replating. I was surprised to find the owners manual under the seat, unfortunately without its cover (I get the impression the manuals are rare and I’ve scanned it if anyone wants a copy). The first thing I noticed when sitting on it was the relatively high bars. My VFR400 is too low but this is very upright for me and it seems the bars fitted to the European model are a little lower? Anyway that’s some way off yet. The pipes are not going back on!

The frame and other parts have gone for powder coating today and and I’ve made a start on the engine. The pistons have a lot of carbon deposits. The exhaust valve in cylinder 4 was very slightly stuck open and the top ring in cylinder 3 had seized in the piston.

A couple of the bores have very slight rusting in places - photo actually makes it look worse than it is. There was nothing worrying in the sump.

The only problem I’ve had so far during disassembly was the oil filter bolt, ridiculously overtightened. The bolt already had slightly rounded edges and would not move. Eventually ended up rounding the bolt head. I drilled thro the head and tried using my largest stud extractor but gave up at the point where I was convinced it would snap. The only remaining option then was to drill with a 20mm bit to remove the head and part of the flange. This allowed me to withdraw the housing and unscrew the remainder of the bolt. Unfortunately I caught the housing which will now need remedial work.

Reading Nurse Julie’s and Royhall’s build threads has been great preparation for splitting the cases hopefully this week. No doubt as well as a rebore and pistons, some big end and main bearing shells will be needed. I’d welcome any advice as to which ones I can reuse.
