Hello people of the Hubb. Really hoping you can help on this one, although not holding out much hope!

So a friend and I spent the last 5(ish) months riding x2 Honda 125s from Ghana to the UK. Great adventure, sad it’s over but now I have a bit of a problem. One of the bikes was left damaged by some dodgy Moroccan mechanic.

Basically the mechanic in question over-tightened the drain plug (where the oil drains out the engine). In doing this, he generated too much stress/tension between the drain plug and the crank-case (where the drain plug screws into). As such, when I came to change the oil – and loosened the drain plug. Part of the crank-case had been cracked, to such an extent it literally broke off when the drain plug was removed. sorry I’m not good with technical terms, I’m new to biking but I will add some photos to help clarify.

Ideally, I would buy a new crank-case. However, the bike in question (a 2015 Honda Ace CB 125) is Nigerian made and I can’t get the part in the UK and don’t get any responses from any Honda Africa contacts I message. With that in mind, I’m thinking an aluminum alloy welder might be able to help – to rebuild the outside of the crank-case and maybe re-tap the plug hole? As I say, new to bikes. So not really sure if this is the right solution.

Financially, the bikes aren’t worth anything. However, sentimentally they definitely are. The little 125 brought us through 11 African countries and I owe it to the bike to try and save it.

If anyone can offer any advice it’s gladly welcome. Or, even better, knows of a cheap aluminium alloy welder in the Bristol area who mght be able to help.

Thanks in advance.

Oh and some photos below with explanation…

So the crank-case should look like photo the first photo

It instead looks like the second

Which means it doesn't create a seal and oil leaks out, as in the last photo

THANKS
