Hello Morgo and welcome to the site from Northern Ontario.
Tell us of any other modes done to your Rocket. Pipes, headers, intake seem to be changed. Was the tune done also? It sounds like you are running too lean and need to retune. The fellows here are the best and will help you get the beast running right.
For sure .
Its a 06 standard with complete jardines (header etc.), and a kn filter under the seat.
Im trying to get hold of a tuneboy set up.
Nearest dealership is 8hrs away.
