Re: newbee w/a Q
I've got a Staton Inc crank drive kit on my bike. The RS engine is a 4 stroke 33 cc not 49 cc. I use the 18.75:1 gearbox. My advice to you is do what David says and leave well enough alone. It's not good to expose your engine to water. If you must ride in the rain cut your engine off cover it and the gearbox then peddle till the rain stops.
