Cam Holding Tool

[r15suk]

I got a cam holding tool for my belt change, but the instructions only say that you need to use it on the vertical belt.

Why is that?

Many thanks

It's because the Exhaust cam on the rear cylinder keeps springing back due to where it sits on the cam

The front cylinder isn't sat in the same position

Thanks all understood now :)
