No they are dry sooty and very black, If i rev the bike hard it bellows black smoke from the exhausts. It has around 11 thou on the clock.

Hi Joe, black smoke suggest to me that the engine is burning oil.
Black smoke is definitely an indication of too much fuel in the mixture, you reinstalled the air filter box didn’t you? It could be an obstruction in the airbox or maybe a really filthy blocked air filter, does the bike tick over smoothly? Could be lack of air rather than surplus of fuel. Who rebuilt the carbs?

If it was black oily soot i would agree but no it is black dry sooty which to me over fuelling but i can’t suss why. Joe

Yes could be. But i had the carbs all rebuilt by Allens Performance. They pressure tested them and ran them on one of their own bikes for two days and said they preformed as they should.

My thought’s exactly but just can’t be bothered with it if i was retired then i would play with it or find OEM carbs. But as it is a dealer has given me a great deal against a 2015 Honda CB500 so i snapped it up.
