No, I started it up and checked in the sight glass, watching the oil mixing with the retained oil, and the vortex in the glass, so it was pumping around the engine ok. TBH my downloaded manual isn't very good and makes it look like the bleed procedure is part of the method for measuring the oil pressure by attaching a guage..
Since I've already ridden the bike 10-15 miles since changing the oil I think it must be fine, but I will do the bleed test as soon as the rain goes off, probably tomorrow morning.
Is this check necessary because the oil light on the TMax is activated by oil level instead of the usual pressure activation?
