What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I was going through a slight curve, not a big one just a normal curve going about 20 miles per hour when I tried to slow down the bike sort of stalled so I went straight into the curb into where I hit a tree. There are many people that saw e incident and found it very strange as well as I did.
The contact stated that while driving approximately 55 mph and decelerating to 35 mph, the handle bars would shake excessively. The contact took the vehicle to the dealer but no repairs were performed. The manufacturer was made aware of the failure. The failure mileage was 800.
Pulling in the clutch causes the rpms to drop below 1000 rpm causing the engine to die or stall. This happens frequently. It can occur several times in a row or it can be several days before it happens again. I've tried to increase idle speed to 2000 rpm, manufacturer recommends 1300, which did not help.
Purchased my ninja 300 3/25/13. Signs of first wobble due to poor head bearing was on 4/10/13. That's only 15 calendar days! My ninja 300 wobbles from decel from 50mph to 35mph.
The engine rpm's dropped lower than the idle speed and the engine stalled as the bike was still moving. I coasted to a stop. I placed the bike in neutral and restarted the motor. It started up fine and I continued on to an intersection where I attempted to make a u-turn.
When coming to a stop with clutch disengaged engine stalled and had to be restarted. Luckily no traffic was behind me or I might have hit from behind.
I would slow down to a stop and the engine would stall. I would then put it back into neutral and restart the motorcycle. It would happen a few times until the motor gets warm, then it stops stalling. It happened to me at least 3-7 times when riding it today. This happened to me about 4 times now.
Pulled the clutch in when coming to a stop and the bike stalled. Happened 8 more times getting the bike home. I have adjusted the idle to 1500 rpm and the bike now drops to 1100 rpm when clutching during a stop then recovers to 1500 rpm after stopping.
