Ran out of gas now have a miss?

[ezlazer]

A friend of mine ran out of gas on his 05 EX Cop bike RK and now it has an engine miss at high speed.  Could that be a gas filter? All stock bike.

May of had some water lying in the bottom of the tank get sucked up into the fuel system and need to have some Heet water remover or dry gas to get it out or just drain the fuel tank.  I remember the first time that I removed my tank from mine, just taking off the cross over hose on the front and draining it yield almost a mason jar worth of water!

I'd at least check for water first.  That is the least expensive thing to do.

It's when ya run outta gas and end up with a Mrs. that you're really in trouble !!

[kickstart]

FI bikes can't do it butt....
If you have a petcock that allows you to run ON or RESERVE, after a fill up run reserve for a while to get gas from the bottom of the tank.
You will keep water from acumulating.
PS don't forget to change back to ON after 50 miles or so

Yikes...That is a lot of water and is one reason why I always top off my tank at the end of the day and store it with a full tank...You get a lot less condensation with a full tank...

Now that gasoline is 10% alcohol, water shouldn't be a problem, or so I've been told.

In my line of work, (lawn & garden equipment)  It seems alcohol blend fuel attracts moisture much more than plain unleaded fuel.   Just an observation.       Marty

Have experienced the same issue multiple times with GM cars and the pump has the same origin. Run it dry and they don't like that. It isn't hard to check the fuel pressure. Do that and be sure to check it while experiencing the issue on the road, the miss situation.

Very funny Mrs. but he says its intermitant and its more like a hesitation or stumble (his words) maybe I should ride the bike and see for myself.  He did say that it started when he ran out of gas.  It has 19,000 miles on it, also he says that he gets only 30 to 31 miles to the gallon, but everytime I ride with him he gets 40+mpg. My Ultra gets 39 to 40 if I ride normal.  But what is normal? 

[rbonner]

Normal is what happens to a biker when he dies.

After draining any condensation from tank, good call guys.

Disconnect the Neg lead on the battery.  15 minutes or so with no power to FI,  Eat a sandwich.  Hook it back up and go for a NORMAL hahahha ride on the bike.  No reving it up, full throttles, just ride it like you are breaking it in.  Put 10 or 15 miles on it and bring it home...

This allows the FI system to find itself and reequalize after running SUPER RICH in an attempt to keep running.  They adjust slightly every time you ride them...  well that time it was having a coronary and ended up with some brain damage....

I thought 06 FI was open loop. How does and open loop system know it's too rich? Max

[rbonner]

Well I donno MAX, I jumped from 94 bagger to 99 bagger to 2001 bagger to 2007, so I'm not the wizzard on all of them and I know they made a lot of changes in there...  On my previous models when they got all MIXED UP that's what I did.  The 99 was a real mess and got rather confused in the spring until it figured out it was a motorcycle and not an M-1 TANK.

Seriously there's only a few parts in these FI systems.

Fuel pump with a fine mesh filter on it.  Chances are no junk is going to get into the pump.  Condensation in the form of water could be an issue as the engine won't run too good if the H2O is too high.  We can fix that with draining the tank.

The next deal is the injectors...  They would have had to be wrecked.  I don't think anything that could wreck the injectors would get by the inlet filter, but always possible.

THats why I'd drain the tank and reboot the computer...  Unless in all the frustration a plug wire got pulled and didnt go back onall the way...

After you have had a few airplane engines blow up on you, you start hearing engine misses all the time.  Been there Really sucks.  BOB
