please help i have just changed the o ring on my pk125ets gear selector but it still leaks my mate said i will have to live with it as they all do it
i just fixed it i used a better gripping o ring and the original one i put on all the way to the top of the shaft so that it sits inbetween the casing and the lever on the inside then filed some of the gear selector of to get it to be a nice tight fit
just dont overtighten
you could try a other O-Ring, one that's tighter and thicker perhaps...
