My bike is stalling when i rev it past 5k in neutral. Also, the fuel injection is a little twitchy on the street. Right now, I have my bike back to stock, so its not a PC map. Also, I have adjusted my TPS. The other suggestions I have heard are 1. adjust the PAIR - no clue how to do this?? please help 2. dirty fuel filter - any tips?? my bike has 12k miles and I always use Shell premium.
