deja vu !

[ade the blade]

Just my quick two scents but I think someone mentioned that Fazers tend to run with a rich mixture as standard so the K&N should help more than hinder. I have one on mine (fitted last month) and it's definately got a bit more power BUT I did renew the exhaust system at the same time...

Actually, could restriction on the exhaust cause the issue? I am not a mechanic in any sense of the word. Hmm, though the Carb cleaner kinda puts a hole in my theory right?

thanks for your input fella.........if everyone could please bear in mind the k+n filter has been fitted in bike now for over 2 yrs with no probs whatsoever. no jetting or carb re-adjusting done at all in that time and its always run sweet as a nut like that. its only now that the gremlins have struck. i could understand if i`d only now fitted a new filter, end can, jets ect but this bike has run perfectly on the present set up with no issues at all.
