Default Jeting on new setup

Well I have decided I am going to buy a new engine and just install my A10 camshaft, Hammerhead performance exhaust, P&P and shaved big valve head, R2C filter, and CVT goodies. Any suggestions on what jetting to use? Elevation is 778ft at home and up to 1800ft where I usually ride. This is also in Georgia/Tennessee so its normally humid in the summer when I do most of my riding. Also I will be using he stock 24mm carb and intake.

Probally a 35 pilot/ 128 main, I would put a new copper spark plug in once u put the new engine in.

Anyone else? That sounds a little low to me. I believe I have heard going up to just a 125 main with just a UNI installed. JerseyDevil, Tom, or anyone else care to chime in?

im going based that your air is humid, and elevation is higher then mine, i bet 128 will be close, even a 130 main might work and then play with the carb air fuel mixture screw to dial it in.
