All Iwis chains are not created equal, go with the Merc Timing chain based duplex from 'Andy' the Chainman. And while you are at it the same chain in simplex form for your cam chain.
I've dealt with the new bloke he's very helpful,and quick deliveryWell Andy has retired but he put someone in charge who will do what Andy has done good custom service as I haven't dealt with the new chainman yet.

Google Andy chain and you will find himSorry Guys, you've got me confused, What is the address or link to Jason the Chain Man?
It's now Jason to deal with and yes he will knowI need a new primary chain and want to get a duplex. Do I need to know a particular one to order or does The Chain Man know what I need for 850 Commando?
