Cured the mayo oil situation that's been present and worsening since my first ride to work (33 miles each way) when the temperature dropped below 9 degrees C.
(and a few mornings of around 3 degrees).
A 230 mile round trip from the Scottish Borders to visit High Force in the North Pennines, cracking roads and very little traffic.
https://goo.gl/maps/wui6ghz7q1wAir temperature 11 - 15 degrees, checked the sight glass on stopping at High Force
after 145 miles, still showing some condensation/mayo.
Rode home the final 85 miles with only a brief stop for a quick drink and pasty,
left the bike ticking over for 5 minutes on the centre stand and removed the oil
filler cap after switching off the engine.
Left the bike cool down while having a spot of dinner, result lovely mayo-free oil!
No doubt it'll be back .. temperature below 9 degrees seems to be the trigger.
