I took the Big Dummy to work today, and I noticed several times along the route that I'd loose power on the Stokemonkey. I'd be cruising along, and suddenly the power would cut out. There's plenty of 'juice' in the battery, so it isn't that. (I've had that happen before when the battery was low.)
I'd close the throttle, then open it again, and the power would come back, but I'd not like this to happen to me when I'm going up one of our long, steep hills.
