Hi again.

Yesterday I was reading thew GS 500 S&RManual. I discovered the ignition pulse generator roataes AT THE SAME SPEED the crankshaft. I thought the generator rotate at half speed because the two coils of my 2001 model. This way, one pulse for each rev, for firing each cylinder.
The photographs show a place for matching the pulso on the shaft, a bit of metal, in order to align it correctly.
I want to know the orientation of it related to the cylinders TDCs, for designing correctly the 36-1 toothed wheel (what is the translation for "roda fônica", the part I am trying to describe?) the electronic ECU supplier said I must use. I need to determine correctly where to drill the corresponding small hole to match the "roda f^{o}nica" on the cranckshaft´s protrusion.

Does anybody who has disassembled the engine and/or knows the crankshaft in order for give me this information?
Thanks.

There is wasted spark, it does spin @ the rate of the crankshaft.
The ones where it spins at 1/2 the speed are usually run off the camshafts.
Cool.

Pretty typical for motorcycle ignitions to fire twice - once when it matters, once when it doesn't. Simpler (no half-speed reductions needed.) Think about it - the second firing is at the end of the exhaust stroke.

I were designing a part, I'd get out there and measure the TDC and relate it to the keyway on the shaft, rather than suffer through correctly interpreting what someone else said about it. I would suggest that you do the same.

We have some cars in Brazil with a sticker in its glasses:

Álcool no tanque, não no motorista.

Alcohol on the tank, not in the driver.

Is there a way to put the crankshaft exactely in left cylinder TDC without opening the engine case?
