renato Posted July 23, 2009 Share Posted July 23, 2009 about 2 weeks ago my 2003 v11 sport cut out while i was riding to work, turned the key off checked all fuses and tried again, bike started and rode off to work, while i was at work i changed out all fuses and let it idle for about 2 minutes and all was good, going home all good until about 100 yards from home the bike cuts out again, the next morning checked the spark with a spark tester and no spark, that same afternoon it started again for about a minute then she died again, relays? should i change them all out, if so what brand is better, i like my guzzi and i dont want to get rid of it, if anybody has any info please tell. thankx Link to comment Share on other sites More sharing options...
docc Posted July 23, 2009 Share Posted July 23, 2009 Relays are a good start. I'm a fan of the OMROM from RYLAND. But many have had good results from the GEI from PYRODAN. Link to comment Share on other sites More sharing options...
luhbo Posted July 23, 2009 Share Posted July 23, 2009 Relais are a good start because they're relatively cheap and easy to swap, even for the natural butcher or baker. On the other hand, they are so simple and undemanding that it's most unlikely for them to fail every now and then. So, keep the actual relais and instead check the sockets resp. the contacting clamps. And get accustomed to the wiring diagramm. If the pump primes and the starter works and so on then why should it be the relais? Be aware that such symptoms could be caused also by a bad phase sensor.

GuzziMoto Posted July 23, 2009 Share Posted July 23, 2009 Relays have caused the exact same symptoms on my wifes V11. I now carry spare relays whenever we go far from home. And the first time it happened my local dealer already new what was wrong before I finished describing what happened. It is a known fault. The stock relays fail. It is also true that some have had issues with the connectors that the relays plug into, so that is the next place I would look. But if you can be more specific about what happens when it doesn't start (does the fuel pump run, does the starter run, anything clicks?) we could be more specific about what to do.

raz Posted July 24, 2009 Share Posted July 24, 2009 how do you tell its gone bad. thankx You could try measuring resistance, it should be 680 ohms +/- 10%. Chances are it'll look fine though, since your problem is intermittent. While at it, clean the contacts. Try wiggling the cable near the sensor when you have starting problems (or wiggle if you have motor running and see if it dies). Check that the sensor body hasn't come loose from the engine block, it's seated at sub-millimeter distance from the phonic wheel inside. Link to comment Share on other sites More sharing options...
lemonjez Posted August 3, 2009 Share Posted August 3, 2009 Had the same problem, pump runs up etc but just dies and then starts again. I ended up pushing the connectors out of the back of the ECU relay base, solder all wires in the spade connectors and clean the spade connectors, gently prise open the little tag that holds the spade connector into the relay base before pushing them back in to the base. Good Luck Link to comment Share on other sites More sharing options...
