Default Re: Engine Fires In Reverse

We usta bump start dirt bikes coasting backwards down a hill. Not all the bikes would run in reverse, some of them were pretty weak, but some of them seemed almost as strong as in forward. We had one guy who would jam through the gears spraying mud and gravel every time he shifted then take jumps at high speed in reverse.

I don't know how the spark is advanced on the china girls, but it seems the timing would be the limiting factor on how a motor runs in reverse. I don't know if you are stressing any bearings or anything. Let us know if it works!
