CB750F2 .... silk purse from a sows ear.

I love the look of the the black 750 - it sort of reminds me of the Harley in Black Rain ... (sorry, I know I'm not making any friends here!)...

Right...the weather has risen above 'bloody freezing' in the shed, and we are back in business with the rebuild project.
Not quite at the point where I can start painting stuff....but it is warm enough to do things!
Yesterday, we dug out hte solvol and the front mudguard and polished it back to a respectable state. There are a couple of minor marks, but it actually looks prety good for an old piece of chrome. There is a bit of rust on the inside, but most of it shifted just fine. I don;t want to underseal the inside of the guard, but I will dab on some rust treatment to kill the rust, then give it a coat of clear lacquer to seal and protect it. I left the rubber bobbins in place on the guard as they are a bit 'solid' but not cracked. Taking them out would have ruined them for sure.
I have got myself into the habit of checking if things can be got before I make a mess of them....
Next...I need to order myself a set of gearbox bearings so I can rebuild the cases. The big question now is do I paint the cases together.....or before I rebuild. Much rubbing down to be done to shift those flakiy bits and prep the surface. I suppose I had also better get a gasket set sorted...and from what I read on here...that's another minefield!
Nurse Julie:
Paint all cases prior to rebuild. Always looks better and much easier to get in the oven and cure in bits rather than a whole, rebuilt engine ;D ;D

On the underside of the mudguard, we discussed recently as to how it can be protected.
Oddjob was doing an original to help conserve it, and ended up with zinc heavy paint as I recall.
I've never thought "underseal" was for protection of metal and to prevent rusting. It's just to protect the paint from being chipped and breaches occurring in the protection that offers.
Any mild steel on old cars that's just been coated with straight underseal always rusts like hell in my experience.
Most effective appears to be zinc heavy painting, and maybe something like coated with silver hammerite to give something of a waterproofing in that underside of mudguard area.
Thread is somewhere but couldn't find.

Found it, this is the one I was thinking about.
