[QUOTE="69ST, post: 174546, member: 5"] The piston in your linked photo looks like a "new dome" configuration, take a close look at the squish band, it's wider than stock 6V, by quite a bit - proportionately. The fly in this ointment...54mm bore size. Subject to revision, that's almost certain to follow with more detailed info, it's looking to me like the flat top piston is a safe "fallback". It'd be very telling to know the TB combustion chamber volume. As long as it's no more than 14cc (12, with a thick composition type headgasket would be close to ideal) this (flat top piston) should be viable. Keep plugging away...we'll get this sorted...
