What do you guys use to bend/unbend the washer that's on the countershaft sprocket? I took mine off last night to fix the chain guide and ended up using the rather rudimentary (sp?) hammer and screwdriver method. It got the job done, but it chewed up the edges of the washer. Also, when you order a new chain, do they normally come with the masterlink? I've seen on many of the online stores where they sell the masterlink. I was wondering if those were replacements or a required extra when getting a new chain.
