Some progress today - makes a change. Have always been unhappy with the oil pressure of the project. Averaging around 30psi. - enough, but only marginally so. Would prefer to see over 40. Just lately I've been pondering how much the cam feeds lower the pressure (they're fed from the oil pump, not the return line as with BSA) so today I disconnected the cam feeds and started her up. Straight to 80psi. Wow, those cams are well fed!
So a question for you guys. There are several ways I could attack this: 1. fit cam feed banjo bolts with smaller holes - there's currently 2 x 2mm holes in each - or 2. put a restrictor valve in the line somewhere, or 3. run the feed from the return line. Which one would you guys go for? Given there's very little pressure in the return line, I'd put 3 at the bottom of my list. Remember it's OHC so the cams need more oil than were it OHV. Another consideration is with as much flow as that, the scavenge pump may not return enough to tank and it'll wet sump.
Second job I did was fabricate an oil separator to fit in the breather hose (not that it seems to need one).
Also, a pair of Amals are on order, but I've a worried feeling the front cyl carb won't fit without cutting out part of the side of the petrol tank. I had to cut a fair bit out of the bottom of the tank on the LHS to clear the mikuni top cap - any more and part of the tank side will have to go, and that won't look good. Rear cyl carb might need a chunk taken out of the oil tank as well. Could be a while before I know, though, as the UK postal service seems to have collapsed. Ordered a grip from USA a month ago. Took 5 days to reach Heathrow, and three weeks from there to me.
