Hello, i ride this Yamaha FZ-6 motorcycle and I experience poor idling and engine stalls during riding, and last time this nearly led to accident, because the motorcycle slowed down in front of an overpassing automobile. I have bought this bike imported from USA. I am situated in Bulgaria, Europe.
My 2005 fz6 ran flawlessly till 4000 mile then the idle was dropping to 600-800 and then would just die. I would turn key off and turn key on again and restart and it would run fine. It happens twice a week. Once on wet pavement it was feeling boggish I pulled clutch to see and it was 600-800 and died.
Motorcycle has been idling poorly and stalling when coming off interstate riding. Gas mileage has also been dropping. Only recently, motorcycle stalled in center lane of highway at traffic signal at night, would not restart. Received fault code 15 corresponding to throttle position sensor. Replaced part.
I had to roll on the throttle to keep the engine from stalling. Then a few seconds later I pulled in the clutch and the engine stalled completely. I was not able to restart the engine after 4 attempts. Then I turned the ignition off, and turned it back on, and the engine started as if there was no problem.
Metzler z4 motorcycle tire (front) internal belt breaking loose at 65 mph in morning rush hour traffic. The tire immediately became so out of round that the motorcycle could not be ridden more than 5 mph.
Rough running at small throttle openings, stalling. Not corrected yet.
The motorcycle loses ignition, as though the "kill switch" was pressed. The rpms drop to zero and there is no throttle response, although lights and gauges continue to work.
2) when I slowed down the rpm's dropped under 1,000 and the motorcycle stalls/dies. It died 3 more times before I could get to a place to pull over. After I pulled over I got off my motorcycle and then let it idle. The idle was low but did not die. I then ride more and it happened 1 more time.
