A full rebuild of this 1958 Matchless G3ls heavyweight engine, still on it's original bore and piston although a Bus could be parked in the ring gaps, that said it is 68 years old was still being ridden.
Whilst down, we split the crank and installed a new big end assembly - although the original wasn't totally worn out you could just start to hear it on the overun.
An interesting rebuild - often is the case where parts become unavailable - this cyclemaster is now using a Puch Maxi Piston following some work to the piston and barrel to preserve original port timings and compression ratio, there is usually a way around most things, the final 1mm of crown height was obtained by repositioning the wrist pin in the piston.
