simonwb Posted July 23, 2007 Posted July 23, 2007 Hi. Posted for a friend: I've got an 05 plate FZ6, which earlier this year I took in to the dealer for the recall to fix the Throttle Position Sensor. Apparently a fault in some machines meant the engine could just cut out with no warning, not something I'd ever experienced before taking it in for the recall work. A week or so ago as I pull away from a roundabout on to a dual carriageway the engine went dead just as I was hitting speed, drifted on to the grass at the side of the road, waited a bit then got going again. Put it down to a fuel blockage or overheating or something (I am not mechanically minded). Roll on to the M40 this morning on my way to work and what should happen but at 70mph with no warning the engine went dead. Pulled on to hard shoulder and gave it a rest, started up again and set off only for same thing to happen a few miles further. Stopped and waited again and eventually nursed it in to work. My question is, does anybody know anything about this problem and if so is it the same TPS thing? Has anybody heard of any other previously fine FZ6s having this problem after the recall? Basically, has the recall now left me with the problem it was supposed to fix and if so how do I get Yamaha to sort it? I called a dealer (not the one who did the work as I no longer live there) who said to wait and see if it happens again then bring it in and pay to get it looked at and sorted, but if I can find out if it is the TPS thing I'd rather not wait. Any help would be greatly appreciated. Any ideas? Please let me know and I'll pass it on. Cheers, simonwb
dansage Posted July 25, 2007 Posted July 25, 2007 Simon, Ring Yamaha Motor Uk on 01932 358000 and ask for technical support. Explain your situation to them and im sure they will help. I speak to them rather that any dealer as i get a quick concise answer. Hope this helps. PS, it does sound like a TPS problem to me. Dan
yoda Posted July 26, 2007 Posted July 26, 2007 This tends to be a fuelling problem. It's the old egg in the petrol tank syndrome. Runs for a time and then is sucked down and blocks the fuel tank outlet. Then the bike stops and after a while the egg floats back up and the engine starts. I'm not saying that you have an egg in the tank, but that you should treat the problem as such. Systematically check all of the fuel run ensuring that it is all free of contaminants and then check the carbs float chambers for dirt or blockage. If you have injectors, ensure that the high pressure pump is working all of the time. If all is well and you might have to do the above a couple of times, check that the battery terminals are not loose.
