OK, disclaimer ... there's some unnecessary detail in this video (like a shot of the brown envelope in which the guy received his CPR kit ), but this video DOES show a lot more detail of what you're going to do with this CPR kit than do the paper-printed instructions.
Hope this helps - it's definitely got me on the right track for today's project.
UPDATE: Spoke with Glen this morning. The instructions say to use an adjustable wrench to more the clutch arm to the left. Though it feels like the clutch arm comes to a hard stop, you can force it further ... "you're only compressing the internal springs more", per Glen.
I was concerned I would bend something beyond its limits, but this advice helped and I'm on my way to getting that rivet out next. I just wanted to take a break and update this post.
Just ordered mine. Rode the bike in to work today which involves a lot of traffic lights and a lot of clutch work. A 50% pull relief will be most welcome.
