CHT at part throttle confirms heat spikes between 0 to 1/4 throttle, jumps to 260-280. then half drops to 240-250, wot to 200-230.
not much surprise as its been mentioned this could be the case, but good to confirm what's going on.
looking into drilling pilot. decided to extrapolate some data from the wiki links in this thread:

- keihin main vs drill bit in.JPG (94.92 KiB) Viewed 7404 times
plotted data, and got this linear equation:
Y = 2500(X)+5
Where Y is main size, and X is drill bit diam in inches.
However, I'm not sure the relationship between main and pilot sizing is same..
from noiseguy on that thread, a .009" bit is a 22pilot
yet equation nets 27.5
only local option for micro drill bits is Harbor Freight, with smallest bit of .5mm, .0197"
which is a jet size 54 using equation, or a size 48 using proportianal comparison w/ noiseguy's #'s.
if stock is 34, 54/48 sounds like a considerable jump. debating trying it anyway, ordering drill bits online, or just leaving as is. YES i still want to keep pod
could all be waste of time, if anything at least this equation can be useful for someone drilling custom main jets!
