    New Regulator Failing or maybe Stator?

    Okay, for those of you that have been following my project,

    i figured out my petcock has to have a manual prime (maybe),

    but i got her running. sounds real nice overall. a noise in the top of the engine at high rpm which im going to let happen for now. nothing alarming though, but definitely sounds like something is amiss.

    now i seem to have a problem with the battery dying. i got it running nice with some idle screw adjustments and i was practicing letting the clutch out and gliding into first (its my first bike and i havent ridden in over 5 years, and when i did it was brief). however, after a bunch of stalls my bike wouldnt start or honk anymore. obvious power failure. display lights going dim, etc.

    but i just bought a new regulator/rectifier for the bike.
    Is it definitely the stator? is there a simple way to test the stator/alternator wiithout taking the bike apart in a sense?

    another issue is: i just replaced the rear master cylinder. the brake works but only after like 5-10 pumps. i'm thinking i didnt bleed it enough. sound right? the lines were at least half empty when i put it on since the old one had been sitting off the bike (not good for the longevity of the other parts i know)

    Go here do the Quick Test- report all 6 results cuz they offer clues. (Note the start with fully charged battery request)



    the battery doesn't have enough juice for repeated starts- bike needs to start and keep running for charging system to work.
    And avoid high rpms till you discover what's wrong in top of engine.

          You obviously have not done any reading about GS electrical around here. Start with the links in the 2nd line of my signature.

            So i took the bike out around the neighborhood for a spin. Rode around for about half an hour. I'm just getting back to riding after 6 years so I needed to brush up anyway.

            Bike stayed fulled charged the whole time.
            I think before i was having so many starting issues that we just drained the **** out of the battery.
            So, my cheap out on a RR has yet to bite me in the ass. I knew full well i shouldnt have bought it. Did anyway.

                maybe he got lucky! I recall someone scooped a used SH-775 for about that price.
