Nice video, but I must admit I was cringing a bit when the hammer was doing it's thing and the cam cover was bouncing around. You'd want a good solid support to bash up against to get the bearing out of the crankcase.

Flywilly, I've still got one of those Dave Shadel Hanno piston and liner sets you organised way back, but the current piston and liner is still hanging in there so I haven't needed to use it yet. I fitted a 140RX pump to the Hanno to replace the leaky original..
