- 6t pinion gear ratio
With that type of engine I have used a ratio of 18 to 1 on a 26" wheel. You can use a jackshaft or get a gearbox with a 3 to 1 reduction.
There are a number of gearboxes that will fit that engine, and yes it will bolt on where the existing pinion gear is now. The 78mm clutch has 4 bolts around it (usually allen head). Remove them and you will see how the engine and clutch mate up. This box should do

ok thanks, im probably going to order this one off ebay
Clutch Gear Box Drum 43 47cc 49cc Pocket Bike ATV Quad | eBay
by the way since putting this gearbox on will make the chain drive facing inward instead of outwards will it risk the chain rubbing part of the engine?
sorry for so many questions im new to these engines

Don't forget that this gearbox will reverse the engine rotation.
If using a shift kit, the engine sprocket should be on the same side as the chainring sprocket.
If using a left-side sprocket, you will need a jackshaft to get power to left side.
For a good gear ratio using one sprocket, it depends what your engine's rpm range is. It also depends how fast you want to go.

This gearbox does not change engine rotation.
However the chain and sprockets are very low quality.
hi !
what type/pitch rear 44t sprocket did ya buy ? as you know the Reduction box you linked at ebay is using like Chain size #20 or something which is miniature chain compered to bicycle chain sprockets, those wont work 2gether, wont mix and match 2gether.
edit iirc Pocketbike/minimoto Cagllari chain pitch is 8mm. and bicycle sprocket has 12,6mm pitch if you bought what im speculating that ya did....Unless if you bought 44t pocketbike rear sprocket ?
DAX sells 10t sprocket that fits into the mentioned Reduction box that you linked. it can use 415 moped chain and 1 of the bmx chains.
the Reduction box at ebay that ya linked is in 2 versions at least, with double row chain/double row sprockets and with single row chain/single sprockets. Reduction on the box can be 3:2 (9t & 29t sprockets inside the box)
bye

As is the clutch bell.......it's a snapper. That gearbox is truly a "get what you pay for" example. $30 shipped is cheap.....so is that gearbox. But it will work, for a while.This gearbox does not change engine rotation.
