my banshee is 3 weeks old, i put the pro flow with a k and n filter on. came with 200 main jets. seems foul the plub in first gear wont wind up then clears up. 32 to 1 mix . when going up a hill im leaving a good trail of smoke. plugs on the most part look dark. i dont want to mess the machine up so any help would be great.

 

your situation is kind of odd. Usually changing to a better breathing filter will do the opposite. It is generally a bit on the lean side. Did you over oil the filter? It is possible to over do it with a K&N. It will pull the oil through the carbs until it dries up a bit. Ive had this prob too. You might also want to make an air screw adjustment. Might need to back them out just a bit.

 

How did you remedy an over oiled k&n air filter? It eventually dried up a bit? I would assume the excess oil would be sucked into the carbs and burned.
