My 99 800 cut kept cutting out on me yesterday, it was raining and I need to run a wire a connection accross a diagnostic plug and count how many times the Fi light flashes to find out what is failing apparently. Is this correct ? If so I can't find ant pictures of what I'm supposed to be looking for under the seat! I'm suspecting a faulty cut out switch as I think this is one of the potential causes of an Fi light. Now to be honest with everyone, I love my vfr but this is yet another electrical gremlin to plague my otherwise perfect bike, I really hate to say it but I think this could be the last straw, I'm seriously thinking of getting rid of her now. --- - Sent from my iPhone using Tapatalk
Magee - Don't give up on her yet. Sometimes its a simple thing that leads to other things. I'll try to help, although i don't have my bike with me today to take any pictures for you. 1. Have your bike on the side stand. 2. Start the bike. If the FI light doesn't blink, there's no record of the problem. If it does blink, count how many times its blinking. If this doesn't work, then you need to diagnose as follows: 1. Pull off your seat. 2. On the left side, attached to the main group of wires, there should be a little 3 plug harness that's not connected to anything else. (I think mine is gray?). 3. Have the bike off (still on side stand). Using a small paper clip, stick one end in each of the 2 outer-most female ports on the freestanding harness mentioned in item 2. 4. Now turn your key on, but don't start the bike. You'll need to count the number of blinks. Note that when the FI light does a "slow" blink (about 1.5 seconds), that actually counts as 10 quick blinks. So for example, it you get one slow blink, then 4 quick blinks, you'd obviously have a total of 14 blinks. Or you might get 6 quick blinks (less than a second each). Think of it as Morse code. The cycle of blinks will repeat eventually, and there are LOTS of codes. You might actually get "slow blink, slow blink, quick quick quick", indicating a total of 23 blinks. If you can do this, and then post up the codes, we can go from there. We'll figure out the code and/or problem, see if we can fix it, then we can reset any codes that have been stored and see what happens. I'd post all the blink codes for you here if I knew how, but I don't. So trying the next best thing.
Ok, spent this afternoon trouble shooting this. The code was one long flash - MAP sensor! Checked the connection to the MAP sensor, looked ok, one thing I did notice was a very filthy air filter, does anyone think this could cause the MAP sensor to think there's a restriction of air flow and throw up an error??? --- - Sent from my iPhone using Tapatalk
One long flash, or one short flash? One long flash is technically the equivalent of 10 short flashes. Ten Short/One long = faulty BARO sensor, which will cause the bike to run poorly at different altitudes. With a faulty MAP sensor, your bike SHOULD operate normally. Its possible that if your air filter is a disgrace, it could be causing problems. After you clean it or replace it, I'd suggest you clear the FI codes and start from scratch.
