i just finished my rebuild bored .30 over, dune port and polish, v-froce reeds, 17cc domes with prodesgin head, pro circuit pipes stock carbs. I'm running in like 70 degrees at maybe 500 feet. can someone get me close to jet sizes? I took it for a ride and checked my plugs, they look like a light brown? is that good or bad? also the bike will idle for a few seconds, then sounds like it loads it and stall. then takes a few kicks to get it started again (3 or 4) thanks for your help
