cliverlong Posted May 12, 2015 Share Posted May 12, 2015 Hi, Just leaving this for info. The XJ6 would cut out 2 or three times within 5 minutes of starting when I was changing up from 1st to 2nd or 2nd to 3rd. Also the engine warning light (yellow) started to flicker. The mechanic could reproduce the engine cut out by "blipping" the throttle. He put the bike on the diagnostic computer and one of the sensors indicated a "pressure" problem (I think). The fault was a split vacuum hose in the fuel supply (?), shown up by some soapy water on the hose. The hose was replaced and since then no more cut outs or engine light. Regards, Clive 1 Quote Link to comment Share on other sites More sharing options...

pilninggas Posted May 12, 2015 Share Posted May 12, 2015 So a vacuum leak, which the Manifold Pressure Sensor detected. Glad it got fixed. I love EFI, it's so much easier to fault find that Carbs [and yes all Yam EFI bikes have easy to access diagnostic modes, so not a closed-shop issue] 1 Quote Link to comment Share on other sites More sharing options...
