How do you flush an engine?
At the last track day, my R1 5VY clutch basket gave up and holed the clutch cover.
I will try and track down the parts, but the engine is dry sumped, and I would guess needs flushing out.
Any ideas where I start?
Would taking the sump plate off and chucking some petrol in where the clutch was be enough, or is it a bit more involved?
Cheers

Big toilet? Sorry 
I would really worry about metal fragments sloshing around in between the bearings and causing general mayhem. Trouble is there are really only two
options
1) wipe out any visable crud and work on the principle that most crud will sink to the bottom of the sump so your suggestion is pragmatic.
2) do a complete strip down and meticulously clean everything....
I'm not sure I'd bother with engine flush or petrol as that's supposed to be for oil residue and won't do anything for metal
fragments other than make them nice and shiney

If the engine is dry sumped - substitute a cheap drill pump, lots of cheap oil & a big magnet.... recirculate till clean!

Cheers gents,
reckon I'll do my best and may be able to spin the oil pump with a drill.
Either way, most of the bits have turned up!
And hey, whats an oil filter for anyway!!

Just a thought, how much work is it to strip & rebuild as opposed to how hard is it to find the money to replace it? If replacing it comes out on
top then clean it best you can with the side casings off then let it take it's chance with more frequent oil changes.
Does it use a magnet in the crankcase to collect debris? Mabye you could fit one in behind the side casings?

Buy some cheap filters, pump the oil then cut the filter apart and look for metal particles. Keep doing it till the metal is gone.

The theory is the only part at risk is your dry sump pump, and if its a system that retains the std pressure pump that too, the filter should have got
the rest ?
If you have the clutch cover off along with the sump pan and have access to an airline blow through the cover downwards ?

Thanks again all.
Malc up north came thru with all my bits. I have an air line too.
The good news is that the bits from the engine bay seem to be nearly all there. I am missing one tab from a clutch plate still.
