Most of these 5-1 gearboxes are good, the thing to remember is that they reverse the rotation. Engine turns counter clockwise so after going thru the gearbox output will be clockwise. What kind of mounting are you trying for?

Was hoping to do axle mount, or not too far from the axle. That sprocket thats on the gear box is far too big but he sells an 11 tooth as well, was just messing with the ratio calc programme so was going to use the 11 and 43 tooth sprockets
 
There are two universal sizes, distinguished by the distances between the four bolts and clutch bell size. Email the vendor and see if he can provide that info.
 
I don't know where peak power band is for GX31 so can't help you on the gear ratio. But think you're on the right track for axle mount drive, plenty of sprockets to work with in 8mm size.

I don't need to ask a vendor as I have a Honda GX 31 and a 5 to 1 gearbox.

The 5 to 1 gearbox is only made in the most common 76 mm size
which is the same as a GX 31 or larger motors like GX 35, R/S 35 cc.

The Honda GX 25 and R/S 25 cc are 54 mm and none of the gearboxes
are made for them. They will work with Staton friction drives and GEBE.
 
Does anyone know if they fit the hausheng 50 cc? I'm hoping to build one with a free wheel crank and shift setup but I can't find any really reliable sources and dax hasn't answered me yet. I found this picture but it's a different motor

Heck yeah that's the 35cc right I'll try to see if I can find the difference. So if I could find a clutch that fit the 50cc shaft I should just have to figure out way to mount the housing
 
I'm not sure but I think you will need an adapter to make the haushung 142f 49cc engine fit that transmission. I believe Staton Inc. sells it. The adapter might make the engine and gearbox too big to fit in the frame of the bike. These are the engines I know will fit that gearbox without an adapter: Honda GX31, GX35. Robin Subaru EH035. Tanaka PF 3300, and PF 4000. Mitsubishi TLE 33 and TLE 43.
