Re: Loss of compression

Yeah, I'm with Kurt--if both valves were tight and the other side was good, it could have been a maladjustment.

My /6 had both exhaust valves receding at about the same rate a few years ago, to the point that they'd both lose the .008" clearance in a few hundred miles.

Re: Breaking News - My Breaks Dont Work

I’m assuming you have a master cylinder under the gas tank. They tilt upwards at the front and can trap air. Unstrap the hose clamp that attaches it to the frame. Then tilt the back upwards and slowly pump the brakes. You should see bubbles coming out of the holes in the master. Like this: https://...

Re: Ignition Issues

The switch in your headlight appears to be the common thing in every situation. People who know /5 key switches should chime in now, but it sounds like a dodgy contact with the key, which I understand forms part of the circuit on those.

Re: Breaking News - My Breaks Dont Work

Sounds like they need a good bleeding! Probably a fluid flush at the same time would be a worthy project.

Re: Idiot v. Motorbikes, Rounds 3, 4, and 5

Charging issues resolved quickly, once the part was on hand. The rotor had failed. So a few minutes with some Allen wrenches and the special rotor tool and it now buzzes the system with 13.5V at 3K rpm. Before rotor replacement the battery read 11.98V and running it (after a s l o w start) showed 11...

Re: Idiot v. Motorbikes, Rounds 3, 4, and 5

So today I invented an errand to get the trans oil good 'n' hot before I drained it. Back home, oil drained, and then I slid the rear mount stud most of the way through the frame and used an ugly carpenter demolition tool to pull the spacer out of the engine case to get access to the neutral switch....

Re: Idiot v. Motorbikes, Rounds 3, 4, and 5

Edgar has had an interesting transition from ON to RESERVE. I'm using angled taps that were not originally on this bike. They'd been on Ernst, my /6 with a big tank, and I'd get 180 to 200 miles on the right tap, another 20 on the left tap, another 25 on the right tap moved to RESERVE and I never qu...

Re: instrument fog

If it's not raining where ZM lives, then the relative humidity is nearly always 100%. I had the same issue when I lived on the coast.

Re: Idiot v. Motorbikes, Rounds 3, 4, and 5

Yeah, out for 30ish miles today after cleaning up the whole area and the neutral switch appears to be the culprit. PRT rubbers are dry, as are the OP switch and the galley plugs. The motor oil I use is greenish and the oil I'm wiping up off the clean case is not greenish. That, and the terminals of ...

Re: Idiot v. Motorbikes, Rounds 3, 4, and 5

Edgar was nice and dry after that fix for about 500 miles but started marking his spot again this week. I was suspicious of the other galley plug, which is accessed from the side. But the frame is in the way, so there was a bit of this going on: https://photos.smugmug.com/Edgar/i-75HKfs9/0/1e4306c9/...
