Hi guys been a while due to work.... Got a new problem I just can't figure out... My bird has developed a intermittent fault? From time to time the engine will just die, whilst riding or idling. Whilst riding though it starts to pull back and surge like it's being starved of fuel and then it will just die. I'll coast to the side of the road and the engine will turn over and after a few attempts it will start and run perfectly again either hours, days until it does it again.. Can be stopped at lights or junctions just ticking over and it will just die, after a few attempts again it will start and run perfect again. None of the electrics will die just the engine. Have checked through the loom and all seems well, checked all breather hoses and fuel hoses and all is well there aswell...any ideas before I start replacing every part on the bike to try find the fault as its intermittent? Could be fpr? Bank sensor? Fuel pump? Or hopefully something more simple? Hoping someone else has had this problem and found the source?
Teef, one thought: The only way we ever get to the bottom of these things is duplicating the issue. This could be an ECU failure issue and you replaced yours. Did you ever put the old one back in to see if it would create the issue again?
No mate I wasn't able to. At the time I wanted the same precise part number that I had previously, I wasn't comfortable putting in just a similar one. Problem is there were literally none for sale in Australia at the time. Mine still started and ran the bike, it just ran as rich as and had the fault code. In the end the only way I could get one was to swap it with a guy who had a wreck but wanted to sell his engine as a going concern. I had to fly the length of the country, fit mine to his bike, start his engine in front of him, buy mine and fly home. So I never got to retry the old one.
I probably wouldn't have either because the faulty ECU caused excessive soot which destroyed the O2 sensor. I'm in a far happier place now
One thing is that my switch block was seriously gummed up with black stuff. As soon as I saw it I knew I was doing a good thing cleaning it.
