I just bought a '97 CBR600 and the chain looks like it is a greasy mess. People have tod me to use chain lube on it but I am wondering if I am just lubing the mess or is anything actually getting to the chain? What can I use to 'clean' the gunk off and re-lube it?

 

Use some WD-40 or kerosine and some rags to clean all the crap off the chain. A toothbrush or 'grundge brush' work very well also. Once you get it nice and clean, lube it up with some good chain lube. Everybody has their favorites.... I like the Bel Ray stuff myself... it doesn't fling off

Also make sure it has the proper amount of freeplay while you're in there

 

I just purchasd an 02F4i as well, chain/sprocket was a mess! used wd-40 cleans well, ended up removing rear tire, to clean sprocket properly! re lubed chain w Bel Ray as well as some chain wax, look purdy nowget lots of rags and use gloves lol and like thirdgenlxi
said check freeplay ofchain etc.

Cheers
