10% leakdown isn't *terrible*. I've gotta think it's something else.
Maybe Fred has it with galled oil pump..
At any rate, 110C (230f) still is ok. But.
FWIW, an AeroShell rep told me one time that 240 was ok with their
synthetic blend.
Cheers!

Here's the latest: It was originally a chain-drive lower end. I converted it to gear-drive, using stock Guzzi gears. My first thought was oil pump, since this one has 80,000 miles on it since I put it on the bike and an untold number from its first owner, so I changed back to chain drive and another 9,000-mile pump. I hate the whirring noise of the Valtek tensioner, but I don't have any more time for messing with it right now. Last fall, when I converted to 950-cc Nikasil, I also converted to run an oil filter. Two days ago I added a sump spacer and tried it with and without another quart of oil. This helped, bringing me up to 45 psi and 47 psi, respectively. The base problem still remains, though: it's heating up the oil too much. On a 70-degree day at a steady 75 mph, the oil heats up to 110 degrees C. That's way too hot. (BTW, you can add a spacer to non-filter twins. Patrick Hayes had one on his Eldo, and I had another I got in a pile of parts that I passed on to another Seattle Eldo rider. I can't remember what company made them. Also, you can add the Escher filter conversion, which includes a sump spacer.) I ran a leakdown test yesterday. Results were 10 percent right (with predominent leakage through the exhaust valve) and 5 percent right. 5 percent is darn good. 10 percent is not. I'm gonna lap the valves, hopefully today. I still don't see how that valve leakage would contribute to the heat problem, but a mechanic said it could because the whole engine has to work harder to get the power to run those speeds. We'll see. Anyway, I think I'm just gonna ignore the gauges and go to the National anyway, but maybe at slower speeds than I'm used to running. GF
