Hi guys, I am getting a real problem with the streetbob on part throttle. Its an 06 streetbob with a power commander 3, supertrapp silencers and k and n filter. It has run well for about 3 years with the above setup but now I get this problem and error codes P0374, U1016 (x2). I have fitted a new crank position sensor and cleaned the aic port at the air intake but the stutter is still there. The speedo is working fine and the flashers are also ok. It makes no difference if the petrol tank is full or nearly empty, Is there any tests I can do before I have to put it into the Harley shop ? Any help would be appreciated.
