Hi guys
Unfortunately my reply to Cranky's post with the photos never reached the internet!
Apologies for my poor description of the oil system.
I meant that the outlet from the oil cooler goes directly to the cams then drains through the heads, barrels, casing in the normal way. Unlike the later 750's that have a return line to the oil pump area.
I will do a hot compression check for blow by. Hopefully that will be ok, as the cold leakdown check was good after I relapped the valves. But good to confirm.
And thanks for the photos. Very useful knowledge!
Cheers
Rob

Hi folks,

I ran the engine for about 15 minutes and the oil pressure reduced to around 6 bar (87 psi) at 3000 rpm and 5 bar (73 psi) at 2000 rpm. So hopefully there is no major blockage in the delivery system.
The oil was still foamed during the running but did seem to clear relatively quickly after the engine stopped.

The hot compression test showed 11 bar (160 psi) from the horizontal cylinder and 11.25 (163 psi) bar from the vertical cylinder. So things look pretty healthy in that respect.
(I have ~ 1.3mm squish with the Pistal HC pistons and plenty of valve clearance with the ST2 cams)

If the oil looks OK and I don't have the same magnetic sludge on the sump plug when I dump this fill, I'll assume all is OK and progress without stripping the engine.

Next will be to finish the wiring, then fit the tank and seat and run it through the gears down the road.
That should be fun. I'll let you know how it goes

Thanks for all the input.

Cheers
Rob
