Just a note to let everyone know that I got the trike started on Saturday don't 'arf sound nice with just the manifolds... It was just a case of swearing at it loudly & getting the timing right ( I think the swearing helped ) thanks to all & cheers for putting up with my stupid questions Jim!!
I've got the early SD1 (76-82) Opus dissy on my 4.6. Ripped out the guts and put in a Lumeniton kit. Then added an MSD 6A CDI and Blaster 2 coil. Works great.
