Hey All,
I think I may have found something interesting. I am not sure. If this is big, please don't make fun of me for overlooking it earlier. Here is the scenario.
The key is out of the ignition, and the battery is hooked up only to the positive terminal, the negative is unhooked and no where near the chassis or anything. When I touch the multimeter with the positive to the positive of the battery and the negative to the chassis there is nothing. As I would expect. When I insert the key, and turn it to on - with the positive to the positive on the battery, and negative to the bare metal on the chassis, there is a short! This shouldn't be should it? There should be no continuity at all to earth from positive right? This could explain why my last battery is all messed up as well as discharged quickly. And maybe why she runs like crap? This could be grounding out my spark! I am a little excited, though I probably shouldn't be, I am! Please let me know what you think! Encourage me! Thanks so much to all who are following along!
Best,
Antonio

Hello All,
I think I got too excited, I don't know yet. I would rather have someone else give me some additional input.
Between battery posts, I get 12.8v.
With both cables to bike attached, I get 12.8v between terminals.
Between Positive terminal and chassis with both terminals plugged into bike, I get 12.8v.
Resistance between positive terminal and chassis with ignition off and only positive cable attached, I get 20kOhm resistance. Same setup with ignition in on position, I get 14.0 Ohms. Much less resistance. Is this all right? I am searching high and low so I don't seem completely incompetent.... What else should I be looking for if I am afraid of a short? I am thinking maybe this could be what is killing my spark. I figure I am definitely getting gas, and air flow is unrestricted. Thanks.
Best,
Antonio

Hey All,
Where did every body go? I am waiting for someone to drop some knowledge on me! Anyways, fail on the grounding issue, I think, I really dont know yet as I can't find any help to confirm this, or how to find a short.
I found something else today though; if I unplug coil three, the same thing happens, of course I can't get it into higher rpms, but could this be a bad low rpm coil? DO these things have dual inner coils? I hear some have low rpm and and high rpm. Maybe the low rpm is screwed on this one. I am still waiting for the map sensor. I also find that the FI light for the map sensor wasn't there today, was a times, then not. Ugh, Keep throwing money at it I suppose. I will wait for MAP sensor however.
If anyone can make sense of this gibberish I am pouring out, that would be great, get back to me with something. If not, I hope it's only beacuse your too busy out enjoying your bikes! Thanks so much!

Antonio

Hey All,
I am still waiting for the MAP sensor, I really hope it will be here this week. I also have a new coil coming, I really hope this fixes my problem. I am getting way too anxious and I really want to get out and ride, it is becoming a horrible obsession and I don't want to be that way. I don't want to think badly of this bike, there is no reason I shouldn't be able to figure this out.
Please wish me luck.

Antonio

Sorry i am late to this discussion but I had a similar problem on my 01 f4i and it turned out to be a fuel injector stuck open. It was full open regardless of if the bike was running or not, so if it sat for a while it would be hard to start because all of the fuel leaked into the cylinder. When riding it would seem super rich from idle to about 4000 rpm then would seem more normal... Hope this helps..

Hey All,
I appreciate all your help thus far. I replaced the map sensor this morning which didn't do jack ****. Go figure! Fuel injection is a real pain in the ***.
Anywho, I was about ready to rip the head off and look at valve clearances. I took the Throttle Position sensor off and fired it up, it fired right up and idled. It will idle all day, it idles around 800rpm and sounds awesome. Of course when I give it any throttle at all, it leans way out and dies. I thought it should idle a little higher, but the idle adjustment is all the way up. I think because the TPS is out, it leans it out to begin with. But when I plug it in, it destroys my gas tank.
Does this mean that my TPS is dead? I checked it with a multimeter today. The resistance seems pretty steady when you roll on the throttle. I don't know why it would mess everything up when I plug it in. Can someone shed some light on this, or should I just go ahead and order another one?

Hey All,
Still no fix to the problem, I have been playing around with the three primary injection sensors. Getting all kinds of weird symptoms. The bike idles around 1000 rpm, but the idler is all the way up.
I got to ride a Triumph Thunderbird sport for the evening yesterday, beautiful bike to ride, very very exciting, I get to thank my dad for that! :-D Bike is just bit big for me at the moment.
Any ideas on what to replace next? I guess I should try the TPS.

Hey All,
This thread has had so many hits, how come no magicians have come along yet and fixed it for me?!
Newb13, I hope your situation proves to be much easier found than mine. I know mine is very minor, the engine runs great with a few sensors unplugged, it idles great, and when they are plugged in, all I get is high rpm greatness! But I can't get both!
One thing I found yesterday is that I don't think the sensor is getting the voltage that it needs. With the ignition switch on, and the engine shut off in the run position, check the voltage between the Red/Yellow wire and ground, then the Red/Yellow Wire and Green/Orange. They should both read between 4.75 volts, and 5.25 volts. I am only getting 0.8 volts, I think this may be my problem, I don't know yet. I had to take my dad to pick up a new bike! I am starting to loose my patience with this little honda! I'm going to start riding something else!
Newb13, stick with me on this one. Why dont you explain more with what your bike is suffering with! We might be able to benefit from each other. Take care bud.
Best,
Antonio
