work to fit Plus heads
« on: 04 Jul 2010 at 09:15 »
Hi all
At some point in the future I will be starting a project to build a 500 Dragonfly motor, I am considering putting Plus heads on.
Will I need to do any thing to either the heads or the fly barrels to make this work?
What valve springs should I use either the normal Fly or the higher performance Plus type. And same for the carburettors, I realise this will mean twin carbs but what type.
I'm not building this for performance but to pull a side car plus those who know me will verify that I'm not quite built like a racing snake!
Thanks in advance.
Regards   Martin
