Alright, chinese cg125. The gear lever seal is leaking, not a major problem but Id like to get it fixed. Iv looked through the part fiches I have access to, so Im fairly sure I can replace it without opening the engine. Can anyone confirm this? Thanks.

Nope you cant theres a collier which makes it impossible to get it out i'm pretty sure.

Just out of interest i had a cg125 1992 never missed a beat whats the reps like ?

Typical chinese, some great others scrap. This ones done almost 10000kms (+/-6000m) and no problems, well maintained to a fault but treated hard.

Mine was maintained well but i gave it death constantly and then sold it.

I miss it so much.

So how badly does it leak. i know it sounds stupid but lean the bike on its side and spray wd-40 all over the seal. It must make the seal expand and it will last for a few weeks just if your in need of it. I've heard of it done before dont know if it actualy works.

Call me stupid

It doesnt look too bad to be honest, but iv just noticed it. Will give it a clean and keep tabs on it. Thinners would also make it expand but Id be worried about degrading the seal further.

Yea true plus it will make it harder to get out probably.

Thinners is an old method for getting rubber to swell, when it dries out its shrinks tho. Just given it a clean and im thinking its actually oil from the chain... Im a twit if it is but a happy twit! Im using gearbox oil in a home build oiler system so heres hoping.

Ah so you have a chain oiler ? or do the chinese have seperate gearbox oils

No a chain oiler, engines are practically identical at least via visual comparison.

I see would grease not be a better idea or what i did with my Honda xlr engined Suzuki LT160 was position the breather over the chain as the upright engines generaly breath quite heavily.
