Must be the worst 550 engine ever...

OMG!!

Is that crank even going to part from the case leaving a useable case.

[Alan H]

I'll fetch a better one down Baz.
We only need the cases from that one in the worst case!
I knew I should have bought that engine you flogged a couple of weeks ago!!

[BAZ]

The cases need a lot of work, even if we can get the Crank out..

[Alan H]

I do have other cases, but not sure if they are M ones, and you know how much I like standard......
I'll have a look what's in 'stock' when I get back off hols.

I am sure you can get the crank out, with plenty of ACF50 soaking it all, and about a month of adding more ACF50 every now and then, may take longer, but one day it will come free, ACF50 manages to seep through where other sprays don't, given time, but who knows what will be left of the cases.

Or have you another method Baz ? such as Deox-c or citric acid, maybe some white vinegar, be interesting to know what you use to eat the corrosion, or how you intend to get that crank out.

[BAZ]

Don't mate life is to short, I think I have some spare casings and these are damaged anyway.

Patience young grass hoppers, its the key to saving originality.

Anything man made is repairable, with the will and time.

But not my bike, so do as you wish.
