    Belt and Suspenders Solution

    About a month ago I reported that once again my SF's crankcase had filled with gas over a long layoff. To make my self comfortable that this would not likely happen again I have taken the following actions.

    Cleaned and refurbished the petcocks
    Added a Pingel Unit in the fuel line
    Added a fuel cut off valve in line before the Pingel
    Added an in line fuel filter
    Did not mess with the carbs since that is an area where I have no competence

    Bike started right up and runs fine. Hopefully this is one area of the bike I will not have to worry about in the future.

    Hey Larry,

    Like you said, "belt and suspenders" solution....because the carbs are where the main leaking problem STILL EXISTS. Yes...it is apparently a SLOW LEAK, so the float valves are not sealing like they need to be. But this can also affect actual riding performance....because if the floats are not sealing well, they can also allow the carbs to get too high a fuel level causing excessively rich fuel levels and poor performance due to possible intermittent flooding and such!?

    SO...what have done is good, but you really should learn to work on your carbs.....will both save you $$ and provide the needed skills to keep them working properly.

      Everyone is afraid of the carbs. We all at one point did everything possible to avoid messing with the carbs. Spent countless hours trying to blame issues on everything but the carbs. Then finally we bit the bullet and admitted the problem was really the carbs all along and just dove into them.

        +1 on the Pingel fuel cutoff, I run one of those on my 79 SF, never have to worry. I have a much cheaper ($45) electric fuel shutoff on my Standard, no wories with that either,

          True OCCASSIONALLY, but normally NOT the case. 'Ignition before fueling' IS the correct procedure when diagnosing running issues. Tis' old school procedure, ALWAYS, and applies here also on these ole' scoots.

            Yes that is true, but he is having carb flooding issues. Explain to me how the carbs flooding can in any way be an ignition problem?

              " Explain to me how the carbs flooding can in any way be an ignition problem? "

              OH OH! I know...because leaky carbs can cause your whole bike to ignite!

              You have inserted a stack of band-aids that might work, but you should get into the carbs and fix them. Working properly, you won't have the leak problem.

                Not related Nate, but your statement MAY have bad implications for other NEWER folks here, thinking to dive into carbs first. 'Everything possible' is REALLY vague.

                  Larry, just so you know...if you own an XS11, you will have to mess with the carbs. Now is better than later.

                      Lots of help is available here to make you competent in carburetor repair. Start with never leaving gas with ethanol in the tank. Put a block of wood under the front tire while on the center stand when parked for extended periods. As mentioned, leaking when parked is also leaking going down the road.
