    Im setting up a tach data logger on my 2013 TXC 250R.

    Does anyone know for certain the number of sparks per engine revolution?

    I would guess 1 per revolution, with the spark on exhaust stroke waisted, but it is possible that it is .5 and only spark during at TDC of the comprerssion stroke and not spark on the exhaust stroke?

    Any one know for Certain if it is 1 or .5 sparks per engine revolution?

    I don't know how the CDI would know that it is on compression or exhaust stroke. There is no cam sensors. Because of this I would think that you get 1 per revolution.
