what size dyna jet kit should I get

NONE!!!!!
Just buy 4 mains for the mikuni. It will be MUCH easier to tune, and your bike WILL run better. Do a search on jetting, or go to the MAIN page, and look at the tech tips under engine. There is a chart that can help you choose the proper jets. If it's just the Bassani pipes, you may not have to change ANY jets, depending on the muffler and back pressure.

I have individual filter pods as well

Here is the link to the "jet" guide.

Use this as a start point and then just test. I think you will only need to go up 2 jets, but if you want all the power, and damn the gas, go up 3 with one size up on the pilot jet.

what size

So what size would that be ,I cant really figure out all those equations

The jet sizes are by 2.5 increments. So, if I remember right the stock pilot is 45 and the main is 137.5. So, 2 sizes up on the mains is a 142.5 and 3 is a 145. 1 size up on the pilots is a 47.5. Get genuine mikuni jets.

As you may have noticed I am not a mechanic but I have basic skills , so if It is in plain english and not tech speak I may be able to figure it out

I just ordered some jets for my project from mikesxs.com. Good prices, just order two of everything and the setup should go smooth. I also am replacing my coils on daily ride. They still work, but have 100K on them, so it's a matter of the coil wires. I'm out of trimming room for the plug caps, and the two "HP" coils from mikes are only $64.00!!
DO READ THE JETS YOU PULL OUT!! I would make sure you have one size either way, so you can do as you want or need.
