So, I think I've caught up with responding to all the comments. Onto the update:
Got the Joker parts in, boy are they cool. The oil pressure gauge is actually a 2 part affair. The first part is the plug into the side of the motor. The second part then pushes in the side whereever you want and is drawn in via an Allen bolt. This allows you to "clock" the gauge to suit.
The gauge itself has a tall stand pipe with a hex for a wrench. The old Steart Warner gauge had a stub with no hex, meaning you had to turn it in by hand.
So the Joker is the better set up.
Got the oil tank clean to suit and mocked up. the Stainless Steel lines are very stiff, and it took some grunting and groaning to get everything to line up. But it did.
The tank is a slightly different shade of gold. It was done at a different time, teaching the lesson, if you're going to have powder coat done in a special color, try and get all the pieces done at the same time. Its hard to rematch the color.
Disassembled the twist grip/quick throttle. Filed out some flashing, lubed everything up good. It works better, still not quite the "snap" i like to hear. After start up, we'll see if flowing some fuel thru them doesn't loosen them up a tad more. The sodablast may have left some tackiness on the slides which would definitely go away with a whiff of fuel.
Halfway thru the session, got a call from Ma, feeling poorly. She's just a mile down the street so we booked it over there. My sister had already called 911. They came and took vitals etc. But luckily all's well false alarm. At 84, can't be too careful. In and out in 30 minutes.
We spent the afternoon putting out Xmas deco, so i guess she's OK.
