A few little teething troubles appeared after the recent service, most notable of which was the oil pressure. Normally the oil pressure sits at 75 psi when cold and rolling at main road speeds, dropping to 25 psi idling after 15 miles or so.
Today, it was going up to 75, but intermittently dropping to 40 or so - very odd. I bled the Morgo again:
When that appeared to be happy - there were no bubbles I turned my attention to the relief valve.
See that bit of debris half way along the spring? I cleaned that out, and after a suggestion from Richard in the AOMCC, I changed the ball and reseated it.
I then rode to Cromer and back, clocking up about 13 miles - until it warmed up, it sat solidly at 75 psi and was still showing 50 psi when I got home. Back to normal.
It’s a bit snatchy at low speed. Initially I thought this was carburation (not that I have changed anything), then perhaps transmission snatch, but all is normal there.
I’m going to retard the timing a bit.
