Bolts didn't want to know. Stupidly, stupidly tight. Actually thought I had snapped the allen key undoing each one. Such a loud SNAP as they loosened. But all the threads were free as.

So out came the Makita and his freinds.

It lol'd at the bolts and even on speed 2 out of 3, whch has packed up, ripped through them.
Unfortunately I chivved up the sump a bit around the bolts which was to be expected, but I thought I'd make them some flat seats.



Unfortunately, the strainer is completely fine. The pump looks absolutely fine. The chain has a bit of play. I assume they aren't designed to be replacable?
The oil is DARRRK black after only 1300 miles. I'm hoping this is the issue. I will be flushing it out with cheap oil twice. Then giving it some more Castrol.
Otherwise I will have to borrow an oil pressure tester then look at the switches.
I've ground down the marks in the sump, will fill the rest (not deep at all) with chemical metal then hammerite it. Either black or white then pink it out.

Why?
Dunno.
