anything else come to mind ?
another idea has come into my fried bonce if i partially (just for testing purpose only), block off part of the air intake, then that in theory would richen the mixture up a bit and smooth out running issues wouldn`t it? (please say yes). thus confirming engine is running lean !!or am i just dreaming and this idea is a load of sweaty bo$$cks !!!!
sorry griff............yep checked all headers ( all four were nice and toasty ) so hopefully plugs ect are firing correctly. will try red`s suggestion with old filter, but will my blocking off idea work also ?
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?
