  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

    000,003 mile 79 1000S on BaT

    My point being: A $32,000 GS1000S shouldn't have a toggle switch with a big red wire zip tied on.

    Informative video on motorcycle oil

    Yeah. That's MA2, MA is still 12-1300ppm ZDDP

    Informative video on motorcycle oil

    It's not the too much zinc, it's the lack of viscosity stabilizers that is the problem. Break in oil is designed to last an hour. Regular motorcycle oil has lots of ZDDP, about 12-1300PPM... and viscosity stabilizers, and anti foam and ....

    I am stymied....vacuum leak.

    If you think you have a vacuum leak: take a propane torch, not lit, and poke it in around where it could be leaking vacuum while the bike is idling. If you find a vacuum leak the idle will go up.

    Plug oiling up

    If the bike puts out white smoke on heavy deceleration (engine braking) you probably need valve seals

    No oil pressure

    You can prime the oil pump through the oil pressure sender hole. Remove the sender and SLOWLY pour oil down the hole. Then remove the gallery plug on the right side, turn over the motor and see if you have oil flow. Remember this motor doesn't have a lot of pressure

    Stater and Reg/Rect problems on 82 GS650Ez

    .... well except you're putting put the regulator in series with the circuit instead of parallel to the circuit. It's not a big wiring change, but it's a big electrical change. You're moving where the regulator is in the circuit, which makes a more balanced load on the stator... and less heat...

    Stater and Reg/Rect problems on 82 GS650Ez

    You're right. I didn't look close enough When the lights are off, the third leg off the stator gets disconnected from the rectifier. Turn the lights on, the W/G gets connected to W/R, which goes to the rectifier. With the headlight ON, you have a three phase alternator, with the headlight off...

    Stater and Reg/Rect problems on 82 GS650Ez

    Not so much the R/R, more how the R/R was wired. Look at a wiring diagram. In the stator all three legs/phases are connected in the middle. This is called a delta, and it means the electrical potential on all three legs HAS to be the same... they're connected. Trace the wiring away from the...

    Stater and Reg/Rect problems on 82 GS650Ez

    That's not how electricity works. You can't "return" current to the stator. If you were to put a AC amp clamp on one of the stator wires, it would show the presence of AC energy, but AC doesn't have a direction, only potential. In DC power the electrons travel from the negative TO the positive

    Stater and Reg/Rect problems on 82 GS650Ez

    Errrr. NO Generators output DC current. (not really but close enough for us) Alternators output AC or alternating current, hence "alternators". Alternators need a rectifier to convert AC to DC to charge the battery. Generators don't... MY GS has a rectifier. An alternator that is regulated by...

    Oil pressure

    The GS motors with roller bearing bottom ends are low pressure. They don't NEED pressure, just flow. The GS (x) motors with "shell" bottom end need the same oil pressure as any "shell" bottom end. You WANT 30psi at idle, and it should increase 10psi per 1000rpm, to a max of around 80psi.

    Wiring ground question

    Pretty simple: Take your multi meter and read the resistance between the steering head and the area of the battery box. Steel frames are OK for grounds for an analog on/off switch, but not for anything LIKE a sensor.... like in the voltage regulator The problem with aluminum is aluminum oxide...

    1980 GS400e Manual Spark Advance / Electronic Ignition

    The slide in your CV carb can "hang up" and do that. You might want to look at the carbs. On every race bike I have ever owned I wired/locked the timing advance cam to full advance, and the revs don't 'hang up" like that. .. and I too am Canadian, and to me a GS is 2 valve, and the GSx is a 4...

    Which thread repair?

    Heli-coil and the like seem to get a bad rep... but I always take it with a grain of salt as usually the guy telling me the thread repair is CRAP, is the guy that just galled all the thread off his sparkplug or drain plug. Thread inserts were not originally designed as thread repair. A properly...
