3AJ swingarm and exhaust onto IVJ?
 

Hi, I've just bought a 1989 3AJ that is in parts, I ride a very tidy IVJ and wondered about the possibility of changing the swingarm to gain a rear disc brake. There is also a complete laser produro system that i'd like to fit, i'm assuming it's just a case of moving a few mounting points?

Any thoughts on these changes would be greatly appreciated, does anyone have experience of the laser produro system, I seem to remember reading that the bike will actually lose power over the standard system, any thoughts?

Cheers

Alan
