KZ750 Jetting
 

I am wanting to verfiy the stock jetting on my 1983 KZ750. When I bought the bike it had pods but I am not sure it if ever ran good. I have cut the exhaust off so now it is simply a straight pipe so I figure even if it was right before it won't be anymore. So my question is, what is the stock sizes and what is the size increase that needs to be done above stock for pods and unrestricted exhaust. Any help will be greatly appreciated.

Not too sure, but I am finding two main jets for that ride, the 62's and the 65's. The main jet 2nd are 90 and 125 stock, with racing only applications all over the place for sizes. Found this info in a fiche.

I pulled the carbs last night and found that I have 65 main, 125 2nd main and 35 for the pilot. From other researching these appear to be stock. I have also read that they should be increased to 70 and 140 for pods and unrestricted exhaust. Using the increase of 2.5 per size that would be an increase of six sizes on the 2nd and and increase of only two sizes on the main. I am totally new at this but logically felt they should be increase in equal incriments. Any thoughts?

You can try it, depending on the altitude and tune, you will still need to fine tune and do a plug chop.
