i need help. at around 13,500 rpm in second gear my bike falls on its face for a second then kicks back in sometimes two or three times real fast. i took it in to the shop and was told there are no codes and everything is working as it should, not so. i was told my power commander 3 could have done something to my cpu, replaced the cpu, same thing happens. i disconnected the power commander when the problem first started and havent run it on the new cpu. any ideas, or anyone had this problem? what could it be?
