Budget CB550, 'Parking Space' Build!
Raygun:
Right, lots of progress!
Both engines are now in pieces.
Top ends: gone off to Julie to be worked on and returned ready for re-assembly.
Bottom ends: in bits, off for vapour blasting this week and I'm preparing to de-rust/clean all the other parts so when the casings come back I can set about measuring up for new crank shaft bearings etc.
Whilst I've got the bottom ends apart this is my 'whilst I'm in there' list of things to replace. Does anyone have any additions?
- Con Rod Bearings
- Crankshaft Bearings
- Primary Chain
- Cam Chain
- O Rings, Bolts.
Anything else that's worth attending too?
Next up after cleaning, working out how the thing goes back together...

K2-K6:
Primary drive "cush" rubbers to add on the list.
Bryanj:
Notnecessarily shells unless worn, damaged, out of spec or you dont know where they fit
Bryanj:
Only on one engine ken, and ive seen a lot worse with no marks on the shells, depends how good the pump screen and filter were
Raygun:
So next update in the engine headache!
Stripped both bottom ends and took a good look, it looks OK in there, the swarf seems to have come from a gouge in the casing where the engine has presumably thrown a chain or caught something and sent it flying around the sump..
Otherwise the head studs seem properly stuck in there and even with an impact wrench and stud extractor I'm having little luck
The heads were assessed and are unfortunately in really bad shape so it looks like I'm on the lookout for new ones of those for both bikes.
A little bit stuck and a good lesson in don't buy a non-runner. At the rate this is going I could be looking for two complete engines...
I'm hoping the bottom ends can be saved- potentially I might have to send them off to someone more familiar with them as whilst I could stomach re-assembly- the measurement and repair of a lot of these parts is a little beyond my experience.
Back to square -2! Not sure on what the next steps are, I'm scouring ebay for heads and barrels that may be better.
