4 speed copy engines

Hi chaps 'I have a 110cc engine which will serve as a temporary engine till I decide on what engine route to take, 4 speed auto, it is the usual drum type selector
gearbox, but I can't help but notice there seems to be no limit stop on the drum i.e it can rotate fully round,.............could get entertaining if you think you are in 3rd when you are in top, any experiences?

Hehehe, i got one of these gearbox in my 50cc jincheng engine on my kids bike.

I promise you that i was very very very surprised first time i drowe that one, from fourth gear into first in about half a second i was streamlined over the handlebars.

Lucky as i was i didn't crash, and the gearbox also survived.
