Remove the sprocket and clean the area around the front sprocket until it's immaculate.

Prop up the bike so it's back wheel is free spinning and let the bike warm up.

Engage a gear and let the counter shaft spin.

Check for oil.. It's most likely the countershaft seal. (Behind the sprocket)

If its not then now the bike is clean, you can see what it is.


If you've stripped the threads on the oil cover then a repair is pretty much your only safe option. Don't bodge it with sealant when you know the threads aren't good because you'll only get 20 miles down the highway and have oil pissing all down the side of your bike, your pants and your rear wheel... Totally ruining your day.

The threads are most likely a M6 x 1.0 (but I'm just guessing.. Find out)

You will need a heicoil kit which includes:

Drill bit specific for the thread Tap, tap for the helicoil size, helicoils, inserting tool, tang punch.

You will also need a tap driver for the size of tap and a power drill. Buy a selection of lengths of helicoils. A set of drill bits is useful too.


I'm also certain that there will be workshops in Ghana who can repair threads.


If you REALLY REALLY (last resort) have to bodge it then using a slightly longer bolt (3-5mm longer) with a lot of thread lock on it can work. The thread depth in the casing is usually longer than the bolts. It's a case of trial and error though.
