    Signal generator?

    So, the cover on my signal generator got ripped off in my wreck, and it looks like the innards took a bit of damage too.

    I'm not really sure what this circuit does, and was hoping for clarification. I tried to start her this weekend, and the starter works, but it's not catching (seems like a no spark kinda situation). Could this be the culprit?

    TIA!

    it lets the ignition know the position of the crankshaft and therfore when to fire.

    pricy items too

    I think and aftermarket ignition might be cheaper if one can be gotten that fits your bike.

      Crap, so then yeah, that would totally keep it from firing off. =/

      I looked it up on Bike Bandit, $180 from them.

        I found one in a parts lot ebay offerning
        a whack of stuff for 19 bucks
        it has yet to arrive and be tested though

        a lot of things can be found if you do a very general search
        especially leaving out the terms for high priced OEM items

        it seems some wreckers work on a volume principal and others research the actual prices

        got a cdi box two forks and a pristine wiring harness for 30 bucks the same way

            Which of your bikes has the problem?

              I'll definitely keep that in mind. =) I was looking as some of the pics I took of the damage on my bike, and it looks like I might be able to fix mine. I think one of the two pickups that are on each side of the crank is bent out of place, so it may just be a matter of bending it back so that it's reading the signal from the crank correctly. I'll try this out either tonight or tomorrow and let you know. =)

                I have one if you need it from a 81gs750 I believe. Has a 1/2 moon cutout on the bottom of the plate. Check your timing advance unit too!!

                  Is this the part



                  Assuming there is am interchange
                  9.99 sounds like a good shot

                    Looks about right Calvin, although the part numbers on BikeBandit only matched on the 1000.


                    Just got home a bit ago from work, btw. Mine wasn't fixable, the black plastic pieces with the circuits in 'em are hosed.


                    Here in a few weeks when I'm actually healed up enough to start working on her, looks like that, a tach, handle bars, and turn signals are all I'll need to have her back on the road. =)

                          if its for the 1980 750 then an 1100 16v should work also.
                          maybe have to notch it for the oil sender.
                          an 8v. trigger will bolt in but i would think the timing would be quite a bit different.
                          i have a small box full of trigger plates for GS 700-1150 @ 50 a pop.

                            The triggers are the same. The advances are different.

                              "advancers" are different.
