Ok, well, I've pretty much been talked into re-using the 234 anyway, it seems to be the more preferred option over the Piper.
So, I'll be re-ringing the (presumably) cast pistons, and sizing the conrods, along with full balance of crank, flywheel, conrods, and clutch cover. So much for a 'quick' check-over lol!
I'm down your way in a couple of weeks, so maybe give you a call and a potential beer/blat with Malcolm?
