G'day all, returning member from years ago. Doing a restoration on my '77 KZ 650. I already have done it once but it needs a touch up again, I intend to use it for historic racing here in Australia. I would like to know thoughts on a 4 into 1 exhaust system for it, are they still available and has anyone used one getting rid of the stock air filter system. I presume there would have to be some re-jetting required. Any info greatly appreciated Regards Neil
I currently have a Delkevic 4 into 1 exhaust on my '78 kz650.
Stainless Steel, and the price is very competitive.
They have two muffler types; straight and megaphone.
I bough the straight, reminding me of the Yosh exhaust I use to have.
I'm currently using a stock air box, but have run pod filters way in the past, with a Kerker 4 > 1.
