Mine is knackered and I'm thinking of having a go at doing it myself but a bit nervous. You need a chain splitter and there seems to be a vast difference in price. Also the chain options are a bit mind boggling. X-ring/o-ring, gold/silver plus the link, rivet, circlip. Where's the best place to buy? It's for an old CBR600f by the way. Any help or advice much appreciated. Didn't put this in Mech tech as its not a bay!
