Just for kicks I went to the Mr Cycles web site and grabbed the following portions from the Signal Generator pages.  Cleaned them up with MS Paint ... hope they help!

what?? u didn't like ms paint l33t skills???   :x

You did fine.  But I was surprised to see the extra-wide tab on the '04 rotor diagram from Mr Cycles.  I made the assumption from your drawing that they were all the same size.

Anyway....

just messing with you kerry.  obviously i still need a few "artistic" skills to be gained in my repertoire.  

So.....the 04+ is firing every 60* instead of the 180* with the 89-03

and both plugs are firing at the same time now but with shorter dwells, must be an emission thing.

.....hmmm....interesting

don't make me whip out a 3d program...

i'll put all of you to shame, shame i tell you!!   :lol:  :lol:

thank you for all your guys help.

This makes me wonder if a 04+ would fit on an older GS...  :dunno:

I doubt it. If the 89-02 won't fit an 04+ I would think that the 04+ wouldn't fit the 89-02. I'm not 100% sure on that but lets say 75%?

Quote from: dgyverSo.....the 04+ is firing every 60* instead of the 180* with the 89-03

Judging from the rotor diagrams, if the '04+ fires every 60 degrees, wouldn't the earlier models fire every 360?  :dunno:

Quote from: dgyverand both plugs are firing at the same time now but with shorter dwells, must be an emission thing.

Both plugs have always fired at the same time, yes?

I see what you mean about the "shorter dwells", but how could that possibly work?  Firing more than once during the combustion stroke - whatever the dwell - seems like a bad idea to me.  I can't think of a good timing sequence for multiple firings separated by even, 60-degree intervals.  :dunno:

My guess is that the "shorter dwell" tabs provide more precise timing information to the "black box", but that the plugs only fire when the longer dwell tab comes around.

Then again, I'm totally making all of this up from the few general principles that I think I have a handle on.  You know what they say - a little knowledge can be a dangerous thing....

I would really like to see what it looks like under the cover. Don't think the dealer would like it if I carried in some tools, so....anyone with a 04+ want to take a pic of the rotor & pick-ups?

Correct. I worded that a little wrong. 89-02 do fire every 360* but fires every time the piston is going up, on the compression and exhaust stroke.

No. There is only 1 tab on the 89-02 rotor and 2 pick-ups, so only 1 plug can fire at a time.

Your comments are well founded. I am assuming that there still are 2 pick-ups on the 04+. But if that is the case then the plugs will be firing on the intake stroke.  

Now where is that pic?!

OK, that makes perfect sense.

Ah ... THIS is what I meant to say.  Not that both plugs fired at the same time, but that each fired at the top of both the compression and the exhaust strokes.  That wouldn't make sense if the intake valve is open even a little bit.  But if we could prove to ourselves that it's closed until after the spark has come and gone....

I just went to //www.mrcycles.com and looked up the signal generator. Per their diagram, it uses only 1 pick-up. Not sure how this works. But then this means that the electronics on the 04+ are not compatible with prior years.

I doubt it going to fire at each of those tabs ... cos one of the tabs is about 45 degrees before the Big tab ... making it fire 1/2 way in the compression stroke ... maybe its for a different purpose that the Black box needs that information.
Cool.

Maybe the smaller tabs act as counterbalances so the timing is more precise, because it looks like they aren't long enough to actually make a spark.  They might have been just a theoretical addition that they threw into the design to make the ignition rotor seem more technologically advanced when in fact it works the same as the old style.  :dunno:

You should put electrical tape on each one of the small tabs and leave the big tab exposed and see if your bike still runs.  Anyone want to wager?  This could be fun.  

Yea shure ... what could be more fun than blowing up your motor Ha...      
Cool.
Srinath.

another theory is maybe they were considering fuel injection, but scrapped the idea?  that signal generator reminds me of a crank sensor reluctor wheel used in many fuel injected vehicles.  

probably not, but its late... who knows

Explain to me how that would happen and maybe I wouldn't think you were retarted.   :mrgreen:  Either it gets a spark or it doesn't.
