My mate’s one developed some weird misfire/stumbling/rough running thing while on the way to work. Relatively recent rebuild, just been swapped for uprated ignition bits (swapped back to old ones, no change).

Roughly compression tested and the front rotor is reading 8, the rear 6 (both of which are apparently good enough numbers for a renesis in isolation, but it’s the disparity that seems odd).

It’s still under warranty from the rebuild so it’s going back early Jan, but just trying to eliminate things that might not be the internals (which is what’s covered by the warranty)...
