Installed a set of Chevy's pipes last week (very nice work btw) and removed the AI. Stock airbox, haven't touched the carbs. Since then, the bike seems to be cold-blooded, runs fine when warmed up, but definately needs more choke longer to warm up. Left pipe is starting to turn a little gold, not sure if this is from idling with the choke on (2~3 mins before heading out) or just a sign that I need to rejet. What do the local experts think?

Thanks,
Rich
