Hopefully someone’s got advice. I am currently running engine Set up. 1197CC. 13 to 1 compression. 22 WebCam, ported head, big Valves,springs  36 Mikuni flats 
Murdoch transmission and lock up clutch. Dyna 2000,Here’s a $10,000 question. Bike pulls hard Not complaining. I am currently running a 137.5 main jet Needle and Excelerator pump seem to be perfect. Your thoughts on the main jet size. I tried to get a plug reading But running 110 Sunoco hard to get a accurate reading. seems to be close but not set on kill on top end
Thanks in advance

If you just started this engine your not going to see much plug color without putting some miles on, run it rich till the rings are seated then do some plug chops.
If its too dangerous to do the plug chops because of a high MPH situation then take it to a dyno to record a few runs.
Most dyno services have AFR sniffers so they will tell you bang on how its running right thru the RPM range.
Don't jeopardize your safety for some tan plugs. I would rather have black plugs than a speeding ticket or accident any day.

Do you mean 122 WebCam? (.460" lift)
