I am thinking about starting a WR400 electric-starter project, but I have a question. What is the common ratio between starter motor RPM and engine RPM? In other words, how many revolutions does a starter motor make during 1 engine revolution, in general?

I have access to the resources needed for this job, I just need some basic information first. Has anyone else tried/heard of a project such as this?

I heard Mitch from Oz was contemplating an electric start attempt. But, he's away on business. Hopefully, he'll be back soon and share his results with us all.

You need to pull the starter clutch cover off a bike and count the teeth on the starter drive gear (usually about 10-12) and the starter one way clutch gear (about 50 or so).
