I started it again today and it fired up 2nd try from a cold start.
I checked both of them for rust,VL400 had some minor surface rust and Silver Streak was like new.
Probably the Perth weather saves them. I was trying to mow the back lawn yesterday and I ended up with a mini dust storm.
I took the muffler off VL400, it looks like it has been running rich for a long time. The exhaust port is 40% blocked with carbon. The piston also had some lines in them. I'm not sure if its scoring, it didn't look too bad. Piston rings are intact and floating as they should.
Someone's had the head off before and it put it back on with no gasket.
I think this one is from the Adelaide factory because of the cooling fin size on the barrels.
This one might run with a cable and fuel tank.
