Any idease what could be causing this? Help suggestions welcome. Cheers Quote Link to comment Share on other sites More sharing options...
james_60 Posted December 7, 2011 Share Posted December 7, 2011 Hi The pssssst then throttle moves noise is normal. Try it without the air filter attached the noise becomes addictive. The lumpiness is normal iirc the 1.25 is a little grouchy when cold and so would you be with a ram air effect inlet in this weather Jamie p.s are the plug leads original. How old are the plugs and when was the air filter last checked/changed Quote Link to comment Share on other sites More sharing options...
