does any one know of a working ratio calcuator. the one on the old post doesnt work any more and im in need of one to move foward on a project
Or if anyone with a half a brain and is willing to help heres what i got
my engine of choice is the german sachs engine (the real old skool 50cc/ama x
2.4hp hp at 6400 rpm (probaly going to gov @ 5900 with a 2 speed tranny with a 4.0 1st gear and 2.21 2nd gear sprocket off the motor is a 13t.
now another factor is this was then ran to a 28t sprocket on a 6" wheel
Now im comming off that motors 13t sprocket to a jack shaft back to another jackshaft consisting of 30t to 30t back to the rear drive wheel of a 30t finial drive. spinning a 20" wheel
this is a trike and im running a 5 speed archer hub which is the 30t to 30t jackshat. And going back to the drive wheel staying with the 30 as finial drive all cancel each other out i understand so that part i dont want to change as i had sprockets machine already.
So where im stuck is the jack shaft between the motor(13t) and rear 30t with 20" wheels
thanks, Pat (i tried to attach photos but they were 2 big)
