take 1 x single cylinder 4 stroke motorcycle-Sump capacity 1.0l of quality oil
Add a nasty split in the back of the petrol tank which by a horrible desighn fault drained fuel into the airbox.
Filling that up to the baffles then drains the air box load of fuel via the crankcase breather into the bikes sump.
Keep adding fuel until there is 3l of fuel in the sump.
Ride said motorcycle till it stops
Drain sump contents to find NO oil just a slightly oily 3.0l (or so) of fuel (mower fuel anyone?)
Concider the options.
Cause of problem is pretty clear.
Damage done --will it run with just fresh oil added?
Bigends fucked?
Crank bearings fucked.
Bore a scratched mess of pigiron?
_Ohh said bike still turns over
