I have an 02 VFR with about 1300KM, on about 4 or 5 occasions the eng dies while coming off high RPM downshifts to a very slow corner (like an intersection) if the clutch is in?? I checked and adjusted the idle, as shown on the tach, about 1300 rpm. Still happens under the conditions above? No other time. Anyone had this experience? ???
Bill- Clutch engaged or disengaged? If you're saying disengaged, you mean you're engine braking from high rpm, you disengage the clutch as you're stopping and the motor stalls?
Thanks for the info about ECM programing, I'll check with the dealer. Rick, thats right, clutch in disengaged. Sorry for long delay in getting back, was out of town. Bill
My '03 does the same as Bill's '02, so good luck with ECM swap. The stalling on my bike is infrequent and easily rectified with one push on the starter. I have had this problem occur with every previous motorcycle I have ever owned (a Yamaha & Suzuki) and almost every bike I have ever ridden, so I am not really concerned about it. Engine stalling under the above mentioned conditions is just a part of the package that comes along with riding motorcycles, like crashing. -Jason.
I have noticed this same thing on my '02 VFR. If this is a known problem, then will the dealer fix the problem like the '02 alternator problem? What exactly is wrong with the ECM?
Hi Gents, I finally got to the dealer for the problem, they checked with Honda and were told there was no record of any ECM problem with this bike??? The stalling problem was known by Honda, and the fix???? was to carryout the start valve scheduling adjustment, reset the ECM, check the sync of the throttle bodies with vacumn, and check and adjust the idle with digital tach (the one on the bike is not accurate enough) Unfortunatly they didn't have the equipment to do the work!! Hummmm, so a waste of my time so far.. I have to go back when they are ready to do this work. I may be going to another dealer if they can't work it out. I'll post something when I sort it out. Cheers
I noticed several more posts on this problem, I still haven't got it sorted out. Ran out of riding weather here in the great white north! Will post something when I get at it April. Cheers
My '05 has done the same thing intermittently since new. I get the same "song and dance" routine from Honda every time I squawk about it. I've talked to Honda regional service managers, two dealers, etc. and no one can find the problem. Honda, Inc. does not seem to care either. To me this is a potentially life-threatening situation. My experience with Honda has made me vow to never buy another new Honda again!
I have never had an issue like this on any properly tuned motorcycle. I have experienced similar issues when the carburetors are not set up correctly but you are running EFI. My 98 does not have any symptoms like you describe. I can't believe tha the dealers don't have the tools required to maintain the bike, I do and I'm just a lowly aircraft mech. I can't say that I have experienced much in the way of spectacular service from any dealer except for the one my family owned. They spend too much time worrying about the shareholders wallets and not enough time ensuring that the customers have an amazing experience. Sad really!:frown:
I have been giving this one some thought. Your speedo is electronic and runs from a speed sensor. I had a car that when the speed sensor went bad, even tho the speedo still worked when I slowed down the engine would die. usually it would start right back up. It could be the speed sensor is malfunctioning If you have a service manual, follow the testing procedures (if is gives you any) for checking for a bad speed sensor. The speed sensor assembly, as shown on bikebandit.com, costs $89.76, should that turn out to be the problem.
Bill, I had the same thing happen on my '05 interceptor a few times. Coming off high rpm's to a sudden stop killed the engine once in a while. I blamed it on the bike just not being broken in fully, and it hasn't happened at all once I put some real miles on it.... I too asked the dealer and he said it should go away after break-in, which it did. I dunno. Still love the bike.
i had the same symptoms on my '02 while hot (above 200, fan on, brake on). i blew it off as being a nusiance and wound up with a complete failure while on a trip, boo hoo. wound up being a battery problem after process of elimination$$$.
happens on my '06 as well. The remedy for me was to up the idle to the high-limit of the idle factory range. Also, the changing of my air filter to a high-flow and/or the change of pulling the flapper door solenoid hose and plugging it caused the problem. Seems like any change in the intake/exhaust system makes it much worse. What makes it worse for me is that my clutch-in sensor doesn't work right, so I can't hit my starter if I'm in gear. I have to be in neutral!
This happens occasionally with my '00 too. I asked the dealer where I bought the bike, fuel filter was one suggestion. 66,000km service is due soon, I'll get it looked at then.
