also for got to add that the bike was sitting for about a year the guy i bought it from rode it with bad gas....i rode through a few tanks....checked the plugs, and they were ok...but i took my tank off as well to check air filter...was wondering if maybe the tank movement knocked something loose to cause it to run like ass... but i saw that it was fault MAP sensor, i checked that it seems its not loose or anything but dont know why it is running like ass but anyways let me know something thanks guys

Is the vacuum hose still connected to the MAP sensor as well as the wiring connector?
Has the bike _only_ been playing up since you checked the air filter?

hose is still there, no the bike was missing a little the first time I rode it with the bad gas but after I ran a tank of good gas it would idle, miss a little but hard none then I moved the tank could I have clogged a injector because even iif I gun it I stall badly

Did the error code stop after you checked the sensor?
You could have clogged injectors from sitting for so long so it wouldn't hurt to clean them anyway but I doubt they'd be any worse just from removing the tank.
It's probably worth checked the fuel pressure regulator while you're under the tank as well as they are a known failure.

Starting it up now haha LOL wow the thing is actually idoling, but still sounds to be missing, but could be plugs no error code up in about 5 mins into idoling so now it's just the missing I'm worried about... And omg thank you it's idoling good LOL that's a start

Cool :)
It's probably worth running some injector cleaner through it anyway.
I've never used any myself so I can't say if it's any good but other people might chime in with some ideas of what you could use.

Also check your oil level and the fuel pressure regulator.
If you smell fuel in the oil then it's almost certainly the regulator.

well the oil level is ok, but the gas smells like it is burning really rich even before I put the injector cleaner, doesn't seem to be making a difference, but I'm still curious as to the plugs but like I said Omg it seems impossible I followed the service manual took the sides of then un plugged fan tried to find the back mounting bracket, couldn't, but even with the sides off I had no idea on how to get to them, on my last bike an r6 I could get to then without removing anything but that was carbureated (sp) but any step by step would help, sry I'm a retard LOL but I wanna learn to do this so I don't have to pay 60 an hour, also how do I tell if the regulator is bad and the location? Is it right under the tank LOL again thank you for the help, and the future help I'm going to need

I don't even know if it's possible to do the plugs from the front :)
It's much easier to prop the tank up and remove the airbox.
The fuel pressure regulator is on the left hand end of the fuel rail.
It has a diaphram that can tear allowing fuel to be sucked through the vacuum line and into the engine.
Pulling the vacuum line off should indicate if it's leaking as there should not be fuel in there. The vacuum allows the fuel pressure to increase in line with the fuel requirements of the engine.

OK, Just checked the regulator pulled the vacuum hose off and yep it was nice and wet i turned the key and gas just poured out of it, so that has to be the problem i went ahead and order on from a honda shop for about 82 dollars not too bad i suppose but should i go ahead and change the plugs, or is there anything else i need to do before installing the new one? just curious of as too how long the new one will hold out is it made better then the old one...cuz i dont wanna have to go through this crap again lol, and at least im doing it on my own haha im proud :patriot:, im guessing i should change the plugs, change the oil, basically do a whole tune up on it before i ride again?

You need to change the oil and filter as all that fuel will have thinned your oil out.
You could possibly run a regulator off a different bike but you'd have to do some research to determine if they're any better.

Hi Guys
I was reading this, having found similar problems with my 2001 929. Basicly it seemed to run on 2 cylinders.
I found fuel in my FP reg as well.
Thanks.

I didn't read all the other posts in response to your problem since there are 16 but I had a similar problem a few months ago with the FI and 2 flashes.

I got the FI and 2 flashes and a lot of back firing and mis-fires. It ended up fowling my plugs. I removed the tank and found that the MAP was completely disconnected from the vacuum line. Replaced the plugs, connected the line and sure enough......

I didnt get any flashes at all. All I got was fouled plugs and a very poorly running engine.
I just ordered the fuel presure regulator so when i get it I'll see if it works.
