Back-story: Im a new Victory owner, and the guy I got the bike from had it sitting for a year plus. The battery had died and the cheap replacement knock-off battery threw a code and the bike rode horrible. A new battery and reset TPS from the dealer and I still have the same problem.

Issue: There is hesitation, pops on deceleration & on steady idle in the mid-range 3k. Lower (2k) and higher (5k) rpms not noticeable at all. Gas mileage is somewhere in the low 30s, high 20s. So I replaced the spark plugs, with no change really. The spark plug wires are in good shape. I ran a fuel pressure test but the bike wasn't warmed up so it only read 15psi. My harley buddy said he made that mistake before and I should retest again when the bike is warm. The fuel pump sounds strong and in good shape when I turn the key before startup.

I ran through a full tank with Seafoam with not much result. The issue still persists. My harley mechanic buddy said get a fuel controller. That's another issue, I like power commander, always have, but I can not find my year/model PC. Any help there would be much appreciated.

Bike Specs & Info:
2003 V92c Standard Cruiser
13k miles
arlen ness slashness pipes
Runs strong if you get on it, cant even tell there is an issue
Replaced the air filter, K&N Air Filter
New spark plugs, stock NKG something or other
Ran Seafoam, running second tank now

Thanks again for the help!

That is the project for this weekend as I have read on other posts that may help the issue. Ive got my fingers crossed it will be something easy like that, knowing my luck though it will only be the beginning. lol. Thanks for the advice!

Not sure why you need the motor warmed up. The pump is sitting in gas and that doesn't really warm up.
Doing a fuel pump pressure test you want 49 to 50 pounds.
Your fuel pump is shot if your only getting 15 pounds

Those were my thoughts, but before I spent the big bucks first I wanted to check with my Harley Mech friend; his thoughts were a fuel pump works or it doesnt. I will retest it again in-case I misread the first time, I did follow the instructions in the Vic Shop video the first time.

Would the fuel pump still work at only 15psi? Would it even turn over the bike and get me down the road because I ride almost everyday and she starts right up (unless it is cold, she takes a few seconds)?

When you clean the TBs, looking on the right side of the bodies you will see a vacuum port 1 in each body. Based on age could be dry rotted. Next is exhaust gasket at the cans. Hard brittle and leak. This could Also be cause of decel popping. I would at least check for exhaust leaks first. Keep us posted.

Cleaned the throttle bodies and checked the gaskets. Still have the problem. The pop is not as noticeable but the hesitation is just as bad as always. Any tips for removing the jerking hesitation while riding down the road?

side note: out of no where my tail light stopped working. Replaced the bulb and still no luck. ughhh! the frustration mounts.

EFI fuel pressure checks depend on the pump, lines, filters, and any return valves in the system. (I'm not a Victory mech but have worked on other EFI systems.)

What most people don't know is when you use an in-tank solvent any crap which doesn't actually dissolve and gets past filters goes into the little screens in the fuel injectors and stays there. (Just spend a lovely day checking then replacing all eight injectors in a 5.3 Z-71 yard sitter I got cheap because it wouldn't start. Most of the originals wouldn't bench check even after a xylene bath and blowout.)

Seafoam isn't a cure-all. You can read its MSDS for what's in it. It won't magically reach into the bottom of the fuel tank and heal any accumulated crud.

Harley mech friend is mistaken re: EFI pumps. The pressure check tells all because injectors require a baseline pressure to spray instead of drool.
What did the pressure guage say when you rechecked? Low pressure can allow an engine to run but would explain pops and odd behaviors. I'd inspect everything relevant before buying parts in case it's something simple. Modern ethanol-infested fuel turns fecal when it sits or is exposed to humidity.

A fuel pump may make gratifying noise yet not actually pump much. BTW never let any EFI vehicle run low on fuel as they rely on fuel to cool in-tank pumps.

Since you say it sat for a year, I'd dump the tank (not drain, look inside!) without hesitation, then clean the fuel lines and inspect the injectors.

Guess he died on the side of the road. No answer and post is a month old

Not dead yet, just working like a maniac.

As for the bike, retested the fuel pressure with similar results. Cleaned the lines, replaced plugs, cleaned throttle bodies all with the same result. Ended up replacing the fuel pump, and like magic the bike runs awesome. I was hoping not to have to fork out the bucks for such a costly repair, but the pressure gauge didn't lie.

Now time to get some apes on this ol' Victory and I will have one awesome looking & running ride!

Thanks for all the information everyone, it was really helpful in understanding a manufacturer I was not familiar with and giving me great insight on how to deal with her in the future...just ask the pros on this site!

Thanks again,
Nicholas

Thanks for posting the followup. :)

Pressure gauges are cheap and easy to use. (They are basically just a simple Bourdon Tube gauge plus hose and fittings, to which you can add other hose and fittings if required or convenient.) I use cheap ones as it's not a check requiring extreme precision, but it's basic to troubleshooting.

I, too, appreciate the follow-up. It's great that you found the issue, and it's one more scenario pasted here to give others a clue where to look next.

Most of my EFI vehicles have pressure gauges in the area before the fuel rail (or TB). The cheap ones can tell you the pressure has changed, even if they are not calibrated to give a true measurement of pressure.

I wonder if your friend was confusing fuel pressure with oil pressure... Nope, that can't be it because oil will drop in pressure as it gets hotter.

Either way, that's one less headache in the garage, and that's a very good thing.
