Wine_maker Posted March 27, 2014 Share Posted March 27, 2014 Hi eweryone! I have problem with my Yamaha Dragstar 400. After standby winter time, farest cylinder begin works inaccurate. On idling it wasn't work at all, cylinder begins work if I close a little the manifold collector of carburettor. Sometimes I hear bangs or pops in the chambers of carburettor. What can be wrong with it? Link to comment Share on other sites More sharing options...
jimmy Posted March 27, 2014 Share Posted March 27, 2014 Hi If you haven't run it for a while it may be that the carb has gummed up with the additives in modern petrol. An Italian tune up* may work, failing that a strip down and all jets, airways etc will need cleared. * Give it a good thrashing Link to comment Share on other sites More sharing options...
