Jeff,
I have found that with the modern unleaded fuel some adjustments to the original carb settings may be needed. On my bikes I use 4/4 slides and 90 main jets - the smaller cutaways on the slides improves the pickup from idle, and the larger main jets help to keep the temperature down on full throttle. To compensate I run with the needles lowered one notch. To obtain reliable starting, set the tickover slightly on the rich side (air screws about 1¾ turns off the stop). With these settings, you should get first kick starting with a warm engine - for cold starts, tickle up the carbs first. I have found the original choke slides to be more trouble than they are worth, so only have them for originality.
Regards,
Eddie.
