    I didn't want to say anything as I don't have any formal training from the bavarians, but an exhaust sniffer sounded a little higher tech than something they'd suggest in an airhead service manual.

    Thanks Alibaba. I didn't look at THAT manual. It's NOT in a lot a them. There's still no CO figures on the fender stickers I looked at. And so on like I said before. They never taught us that method in BMW service school. But there is a CO figure. I wonder if any other models have a CO figure? Doc says his spec is 1-3%. What model is that? I don't have all the later manuals. The last sentence is pretty telling. I suspect that would go on a lot without a much more specific procedure for getting those numbers. K bike manuals and F650 manuals do.

    Then there is my main point about using a gas analyzer on a aircooled motorcycle engine with no load. It's a joke. They are bad enough on water cooled engines. I still can't think of anyone besides DT that uses one on airheads to adjust the mixture screw. Different story on a dyno with a load on the engine.

    You'll be OK up here with stock jets. it is when people rejet for up here they have lean issues at sea level. The only thing it would do is run a tad rich up here and that aint bad at all! I run what would be stock sea level jets in my 1977 R100RS and it runs spectacular up here all beit a tad rich, blacks the pluggies after a month or so. No sweat. Still honks along great.

    Correct; and if I were to visit my brother in Long Beach, CA, I would pop my stock jets back in.

    Sometimes a tad bit of JoMama creeps in unwanted.
