    So I bought my right bend the other day and eventually im going to rebuild my blaster and have it ported with the head modified. my friend bought a project blaster that has boyesen rad valve and reed spacer. He bought a 34mm carb for it then realized it was way to big, I asked if he wanted to swap carbs and sell the reed spacer to me and he said he would straight swap me his whole intake setup for mine! So that brings me to this question. What jets and needle should i be running in a blaster with the rad valve, reed spacer, ct header, uni filter, and no airbox lid?
    Oh it is like 800ft and 40 degrees here too.

    Assuming this is a keihin carb (?)
    I'd buy....
    48-50-52 pilots
    DGH or CEL needle
    155-165 mains.

    Those are just suggestions based on my 34mm experience here @ 1800' elevation and bumped up slightly for your lower elevation.
    You must go thru the tuning procedures and plug chops for each jetting range. Start rich and work down.
