I made a dipstick that hooks over the filler neck, filled the tank to recommended capacity, marked the dipstick as "FULL". Pre- ride prep is to check the oil, I know how much the level drops before it starts to smoke or splurge out on start up. So decision time before riding, either let it smoke or sump drain and recycle the oil. Depends on the level drop.
Off the wall thought. Before setting off in a small boat, first thing to do is pump the bilge. So why not on an A10? Looked into a cheap oil transfer pump permanently plumbed into a drain plug type sump plate, back to the tank, powered by bike 12 volt supply or external power source. So, a clean hands solution to the more persistant offenders.
Bit of a hammer to crack a nut, I can live with the wet sump syndrome, so never got round to doing it, but it has a certain crazy appeal.
Must admit heart rate always drops as the standard oil return gulps into view, showing that at least half the pump is working!
Swarfy.
