clean the carb.. the pilot jet is plugged, remove the carb and completely clean every jet with carb cleaner and compressed air.

here is Pro Circuts jetting chart use that as a starting point if your elivation is close to sea level. jetting is somewhat machine specific meaning, what works in 1 bike may not be the best in another identical bike

99 PC jetting guidelines

there has been some really good jetting threads here in the past.. do some searching so you can fine tune the bike for your specific setup.
