Doms CB550F1 project
Nurse Julie:
Lots of pitting on the shells and a gouge out of the left side.
DomP:
OK, so I need to be determining what colour shells I have fixed and replace all marked shells? The crank appears OK to me
Trigger:
Gear box dogs look fine. I would plasti up the shells as long as you run your finger nail across the crank journals and don't feel any grooves ;)

Can't feel a thing Trigger, I'm not sure what step to take next to be honest...strip it all out and clean it up and check bearings? From what I can see the primary chain hasn't either the casing at all.
Oddjob:
Far better than I expected Dom.
You need to rotate the gearbox and take another pic, although it looks fine in the pic posted there could be damage underneath we can't see.
Shells don't look that bad TBH, some minor pitting, most likely from contaminants in the oil sitting against the shell when it's been stood. Crank journal we can see looks ok.
Primary chain looks toast TBH, but check with the tank track test and see what it looks like then. Strip the engine completely, if nothing else it needs a really good clean.
Gear selectors look fine.
Anything sitting in the sump? little bits etc.
Looks like the dreaded red hermetite or instant gasket, really plastered it on either way.
Can you see the crank markings? the printed letters and numbers? What are the letters on the back of the lower crankcase as that will show what colours you should have fitted, well within 2 colours anyway.
Need more pics but looks good up to now.
