these chineese 110/125 engines etc gearbox's have a limited lifespan I have found . I have used one of these and found it lasted no longer than anything else on the market . They are not the easiest thing to install either unless you are familiar with the engine and have a couple of special tools needed for rebuilding and pulling one down . It's almost easier for some people just to buy an engine already kitted with one as these engines are **** to rebuild . I mean the casing casting is so soft and inconsistent if the gearbox does last it will just eventual punch through somewhere, I am not joking .

They seem to handle a single rear wheel of a dirt bike on loose dirt ok , put one in a quad with dual rear wheels and they don't last long ( done this once), rebuilt it with 5 speed box and kept auto clutch then transfered it into a bitumen go kart, lasted not even 5 laps . Done this again with a fully clutched new 125cc lifan 4 speed and lasted even less than 5 laps .

And it was always 3 rd gear that was the problem or went first .

The problem is these engines were ripped off Honda CT110 postie bikes . 3 speed/auto clutch . They have their limits and with a lot of these dirt bikes etc you are basically utilising something it was never ever designed to do .

Did you use the Alex 5 speed gear box or did I miss seeing another?

I have used one once and it lasted no longer or shorter than stock .

It doesn't add top speed if your thinking you have another gear to go and reason for doing it . Just spreads the gears out differently .

About the best mod anyone can do to these engines is the internal fly wheel magneto you will see on Ebay.

That with building a dual vacuum fuel pump between the tank , carb and removal of floats and seat with a return line run along frame and returned back through the breather on the fuel tank cap .

You can also machine roller bearings into the top Cam if your engine doesn't have them .

Best to start with an oil coiled 140cc Lifan .

There has been the Takegawa 5 speed and 6 speed gearboxs out for a while now that are full Japanese built. but still they dont last.

just buy a good 2nd hand Jap 80/85cc mxer and be done with it .
