The magneto on the Beeza packed up a couple of weeks ago, but I only got round to whipping it off yesterday. So today I thought I'd investigate the rattling noise that's been bothering me for a while. After taking the head off my first thought was piston slap, but when I got the barrel off I knew the big end had gone! So I'm either looking for a reasonable B33 engine, or I'll re-build the crank and bore it to 400 using a low comp 76mm Triumph piston.
