Anyone have an idea of what kind of current a dirtbike starter pulls?
I've heard speculation on some pretty big numbers (like 80-150A), and
I can see there being a pretty big starting surge, BUT once the thing
gets spinning, it seems like there isn't a whole lot of power required
(we all can spin these motors up with just one of our 1/8HP legs,
after all). Any relavant insight would be helpful.

Each compression stroke will have a higher draw... but we talkin' a
CRF230L or an XR650L?
Or something high compression?

CRF450X (or YZF or other equivalent).

guessing cheep engineers will have the draw about 3/4 of what the battery
will muster... otherwise they would put a smaller battery in there..right???
