Main Jet size
Yes. Drill the carb' vent hole to 7/64". Don't bother with any mods to the spring, just put it back the way it came out.
For your elevation I'd go the #128 main jet, #35 (stock) pilot jet. and start with the fuel screw 2 turns out from lightly seated.
BTW, the non USA jetting for a stock (choked) bike is #132 main and #35 pilot. Just fit the #128.
You'll be amazed at the difference for $30. (OE N1TC needle, collar and clip, OE#128 main, OE#132 main.)
Don't forget to remove the snorkel.
