hi i have a 1999 gsxr 600 with a k and n air filter and blueflame exhaust.
i keep getting this problem of my bike sounding like its only running on 3 cylinders. it doesnt happen all the time it just comes and goes as im riding.
i have had it in a garage and they have striped my carbs down and cleaned them, also they have serviced my bike i e new plugs and re oiled my air filter.
does anyone out there know what could be causing this problem cause its driving me bloody mad.It starts up fine does sound like a slight misfire though but i can go on a run and the bike is perfect and then al of a sudden it sounds like a tractor and the performance is seriously reduced.
Please someone help.
