All done!
Turns out the larger main jet (88) and shorter jet needle (N25WK) belong to the left hand carburetor since that cylinder runs hotter.
Running sweet with both pilot screws at 1 + 1/2 turns out.
Local radiator shop told me it would be pointless to flush the tank unless I am going to Red Kote it. Ended up just installing an inline fuel filter (Walbro 125-930-1) which I bought from my local lawnmower shop.
Been having a blast riding around on this thing
Thanks to all for your input
