New exhaust and air filter, need jetting help

ryguy85
I have a 79 CB 750F and I replaced the air box with 4 K&N air pods and removed the muffler, kept the stock header (4 into 1). When I am determining what jets to run, can i change the jets of 1 of the 4 carbs, test it, see how the plugs look, or do I have to change the jets in all 4 carbs before I test it?

Any idea as to where I should start on the main and pilot jets?

I have never heard of anybody doing it like that, but it's worth a try.

I was thinking it'd be easier so I don't have to buy 4 sets of jets, replace them in all 4 carbs, run it, see that it's not run, and have to buy 4 more jets and replace them all again, etc.

I dont see why it would not work. If the other three cylinders are off/not running right you won't be able to tell much.But you should be able to read the plugs ok with your method. Let us know how it works out!
