Historic Code

Heading to work yesterday morning,it appeared the engine light stayed on a little longer than it should...Got to work, shut bike off,then turned ignition on again...sure nuff, engine light comes on,goes out then comes back on again for a few seconds...indicating a historic code...
Going for lunch I was leaving a stop sign turning right, bike quits/stalls...just what a guy needs with a messed up back,bike leaning to the right for a 90 degree turn and it stalls....fired right back up...got to restaurant,it's idling fine but I notice gas gauge dropping down to empty

No previous issues,except a few weeks ago at a stop light it stalled on me and had a low idle...Breathers are routed to atmosphere so I didn't think a dirty IAC would be the problem...
Found on the innernet how to pull codes through speedo so when I get a chance I'll do that...But in the meantime any ideas what could be going on??

Battery voltage OK? Might be enough amperage to start but not properly run all the electronics, especially once charging system heats up with engine running awhile.

Yeah cowboy,it's the cop king...New fuel filter last year,new Deka battery this year...I read HRK's reply yesterday afternoon(real busy at work) so when I was leaving I took the gas cap off and tried to blow through it...what a head rush... couldn't blow thought it at all...1st bike that I didn't modify the gas cap vent with an awl and a hammerleft the cap loose and the bike ran fine on the way home So the gas cap could very well be the problem...Gonna run some Seafoam through it in case the injectors are a little dirty....But,I think HRK nailed it:cheers:

Yeah, that would be good if it's just the gas cap. A little Seafoam won't hurt anything either. I use it all the time - just pour a glug, glug in the tank when I gas up.

It would be good...I never would have thought of the cap not venting with a fuel pump on EFI...I was figuring some sensor was going south....kinda weird watching the gas gauge dropping down from 3/4 to empty...I was letting it idle while watching the gauge drop and was wondering if it was going to stall when the gauge hit empty... lol
Think I'll have a couple of Red Neck Bud's and "modify" my gas cap
Fuel Moto is where I found the info on how to pull codes

Harley Codes - Fuel Moto

Not 100% sure that's the problem...but it was a very good suggestion that makes sense,(cheap and easy too)I guess when I get the code and it's low fuel pressure or something around a fuel issue...When this EFI bike acts up it does make me wish it was a Shovel or Evo

I had that issue with my Sportster when I bought a fancy pop up gas cap from Drags. What a piece of siit it was. I put the stock on and haven't had a single issue.

Me too...Gas cap is modified...Only took 8 Red Neck BudsIt will not not vent again Let's see how she goes...

Well,can't use the link from FM to pull code...Mine needs the little jumper wire in the Data Link connector...I remember making one up when I got the bike...Now, where the hell did I put it
On the plus side,it seems to be running better since I adjusted the vent...but I'd still like to find what hiccuped and caused the historic code,before I head out next week...I wonder if the dealer has 2 pins in stock

lol.. What ever the problem was it came and went away(like a hiccuplol),that's why it's a historic code...something slowed the fuel flow/pressure down...gas cap is a whole lot better than a fuel pump...
I'm taking it to a shop in the town I work in....he's going to do a leak down,compression check and check the oil pressure ...Might as well get him to check fuel pressure too....
He's got a mid 50's (I think it is) Triumph custom he put together,pretty cool looking bike I'll snap some pics when I drop my bike off to him.....
