Putting an excessive amount of heat into the clutch during the burnout can cause your bike to creep or pull through the lights. You can help alleviate this problem by maintaining a high enough RPM during the burnout to keep the clutch from slipping. Try tipping the bike to the right, after the burnout to get some oil on the clutch.

If you have an air control on the clutch release, make sure the hold pressure is high enough to keep the Gen II from overpowering the release cylinder.
