So for those interested
My Bike is a Kz750 B1 (1976)
Its running a standard 750 CSR Exhaust
I have upgraded my Carbs to Kawasaki GPZ500s units so they are more reliable and more economic than the standard ones.
To do this I had to swap the standard 38mm inlet rubbers for ones off a 750 CSR these match the 34mm Gpz Carbs.
I have also had to set up a Choke Cable on the bike. I used a universal pull & twist car type used on old Mini’s
My Carbs are also running Pod Filters as I have done away with the standard air box.
This ment that I have had to adjust Jetting and Needle settings
Main Jets 134/5
Pilot Jets 40’s
Needle setting is 3rd notch up from the bottom.
I have then set my air screws to get the best running I can & then Balanced the Carbs.
This seems to give me quite good running. Well I’m happy and my bike now feels quite smooth. But I will have to get some miles on her as Michael said in a previous reply.
But If I have to make any other changes I will make sure I post them on here.
I hope I haven’t bored you with my obsessive posting of work I’ve done & that this information is of some use to somebody If not now maybe it will be in the future.
