O.K Boy's here's an update!
Got home from work, could'nt resist getting straight out to the shed, checked;
Air filter box; Clean
Sump & filter; Clean no leaks
Oil levels; Good
Got some Silicon Grease, removed grommit from pressure switch, Moisture evident!!
bit of a ****** to get too, but cleaned out, loosened then tightened end screw on wire/fitting, end of switch. Covered in grease.
Started bike, no more "low oil pressure light"! Possibly cracked it? well done all especially NIBiker! you got me thinking.
Now I'm still not sure where all that oil went?? So next service I'm gonna get her comp tested just to make sure, but in the meantime, I'm gonna fit an Oil pressure Gauge!
What pressure should i be looking for Gang? Any idea's as to where i can buy the kit?
Thanks again to you all for your imput and time
