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?
