Hi all, I'm planning on changing the size of my rear sprocket on my 09 CB400. The guy at the Honda dealership reckons I can just nip the pins out with an angle grinder and use a generic master link to shorten the chain (sounds dodgy to me but that's never stopped me before). The user manual however says I must use a staked master link. The chain is an o-ring type, do I need to use a staked master link? Also, if i'm going to buy a chain breaker/staker (if there is such a combination) any recommendations? Any advice gratefully received.
