Day 2... Not gone as well as hoped. Bad news is he bike won't start at end of day.
But it had started through the day, so will need some diagnosis.... And didn't even get the main engine/tranny/final drive fluids changed
What did go OK...
Fuel filter replaced, no real dramas.
Coolant change, ok. Bike started and ran OK while we were burping the air from the coolant.
Clutch fluid change.. OK
It was now getting on in the day and I discovered amongst the vast array of tools we have that we did not seem to own a 7mm open end spanner needed for the ABS control circuit flush.... Bummer. 7mm fits the 2 tall bleed screws on the ABS unit. Those ones that are REALLY DIFFICULT to get at.
Was going to call it a day, but the local hardware store still open so we whipped down and bought a couple.
Did both control circuits OK (I think) although there's 2 points I'm concerned might have something to do with non-start....
To get the bleed screws opened (port #3) I removed the ABS electrical connection as described somewhere amongst the videos seen and procedures/threads I've read.
When we did the front control circuit the bike was not only allowed to go through the initialisation sequence, but the starter was accidentally pressed and kicked the bike over.
I'm hoping this hasn't created some fault code in the system stopping the bike from starting.
The second thing was I had to twist some of the cables tied to the frame out of the way to get the funnel in... Hoping I haven't disrupted an electrical connection somewhere.
Anyway, got the wheel circuits flushed OK without installing the speed bleeders, just using JZ's suggestion of hanging the bleeder bag up high so air could not go back into the lines.
What I'm hoping has gone wrong is that the flushing procedure has drained enough juice from the battery to stop it turning over, and nothing else is faulty..
When I turn the key ON, I get normal warning lights sequence, ABS warning light flashes slowly, then when hitting the starter button I get a single "Click"' the headlight dims then brightens again, but the starter does nothing.
I've put the battery (BMW oem gel) on a trickle charger overnight... Will reconnect it in morning and see if I get it to kick over.
Appreciate any thoughts to help with problem solving while I sleep off the dismay.
