new MOT emissions

[onedayTM]

Been off build for quite a while for various reasons and now thinking about starting again on build. Someone mentioned this new law to me which means disaster to me as bike carb rebuilt on manifold on '92 zetec silvertop..
So this new rules means it's all junk! What sort of second engines are we now supposed to be looking at to Pass Euro6 , is it possible for amatuers to pass such a strict system.
Do I jack it in and buy secondhand car, will this re subject to new law or is it just new builds?
