It's not too bad but the front plug is consistently more black than the rear one. Not sooty just more carbon. What should I check for? The bike runs real strong and all the vital signs are normal, i.e., AFV, etc. Leaning towards the front intake seal since I had to wrestle the intake a little while trying to get the throttle body off the bike last year. Thanks. |

Forgot to mention I did the standard "spray" tricks to check for the leak(s) and no change in engine speed... |

Makes sense. I must have a very small leak since the air gets sucked in at higher engine speeds. I guess I could take the easy way out and tweak the fuel map(s) to compensate for the leak but I just happened to have (!) a whole new intake manifold assembly with seals and injectors sitting in the garage. |

air leak is most likely at idle at Cruise RPM the throttle is open less vacuum may also be an injector issue, any one know the leak test? |
