    Diagnosing misfiring issues on a 1979 1000SP

    What I mean is going to a bigger carb isn't good if the engine isn't designed for it. That 40mm carb on that engine will not atomize fuel well until you get above 6,000 RPM. Same holds true for jetting and so on.

    Codes 27 & 31 - non start

    With an account upgrade, you can get the colorized schematics. Wire colors may change in the harness so no correlation of wire color at the injector to the relay. Do get some contact cleaner from an auto parts store and clean up any corroded connectors you can find. Which after seeing your...

    Diagnosing misfiring issues on a 1979 1000SP

    You should have no more that 10psi difference when testing. Looks like right side is oil contaminated. Testing hot or cold makes no difference when diagnosing compression. Do test with the throttle wide open. It appears a tear down on the right cylinder is in order and a leak down test will...

    PHM 40 float valve size

    The 40mm DelOrto is way too big for that engine. Go back to the 30s if you can, or at least the 36s. There is a formula for carb sizing in the downloads. You will have to be running about 7,300 RPM for the carb to be at the efficiency level for your bore and stroke.

    MY21 Paint

    Guzzi does not publish paint codes. You will need to take a sample to an automotive paint store that can computer match the color.

    Gonna try it...

    The synthetic oils stick pretty well. I've let my LeMans sit for some time and when I do a valve adjustment there is plenty of oil sticking to the components. The only oil I found that didn't stick well was Amsoil. I though I'd try it but drained it after I found it didn't stick like Mobil1 does.

    Gonna try it...

    May not be beneficial. The synthetic 10W60 should hold up just fine if changed on schedule. Remember the truck shop is diesel engines, water cooled. Your bike is air/oil cooled. Lucas makes good products. I use their synthetic grease, and sometimes put some of their fuel additive in the...

    Where does this screw go?

    Or look for a hole that doesn't have a screw in it!

    Griso Lighting upgrade to LED

    Unfortunately, not cutting wasn't an option as I couldn't find connectors. Besides, the stock light is so bad I wouldn't want it back on the bike.
