Vance & Hines Fuelpak Talk.

[Ultra RB]

I have a 2008 Ultra, SE air cleaner, V&H FuelPak and V&H Ovals. They pop like he11 when I decelerate downhill. I've called V&H several times and in spite of several modifications they can't tune it out ... and they have now given up telling me "that is the way it is with such an open exhaust system."

Personally I think that is bs considering it's their pipes and their EFI module but ok, I'm tired of this and give up ...

My next move I think is to try something different and believe I want to try the SE Street Performance Touring Mufflers (pn 64985-07A) ... that way if they pop I can scrap the FuelPak all together and just get the Harley stage 1 download directly to my EFI ... and hopefully the Harley engineers have that figured out using just their products.

My questions ... anyone got this SE Muffler setup? Any popping? What is the tone of the SE's vs. Ovals?

I find the Ovals to be pretty loud on my bike, maybe a 8/10 ... while the stock mufflers are way too quiet at a 4/10 ... plus there is a noticeable power increase with the Ovals.

Thanks,
RB

Just an fyi...

I had the SE Performance touring mufflers on my '05 Road King. They are very quite. I highly doubt you will be happy switching from the V&H pipes to them. They are barely louder than stock, and I mean barely if at all...

Good luck & ride safe!!

Hi RB.

Ok, First thing to look at is the exhaust gaskets and the slip joints on the pipes.
Any air leak will cause any pipes to pop and backfire, I suggest replacing the gaskets at the head and then use a some high temp silicone on the slip joints.
Then see if this helps. Any free flow exhaust can be pledged by popping a gurgling, it just part of how they work, but it shouldn't be like this, it should be easy to ignore.

Try this and let us know.

I just love the pre-EPA SE mufflers #64903-99 on my 2008 Ultra. Sound-wise I believe they are right inbetween the Vance & Hines mufflers and the whisper quiet stock cat-mufflers, which held tons of heat. My '08 Ultra sounds great now with plenty of robust deep sound, runs nice & cool, and mileage so far has remained the same so far averaging approximately 42 mpg. This is double up with bags filled and averaging 75 mph. Also, no popping whatsoever, very smooth.

I had a hard time finding the older SE mufflers and kept getting beat out on ebay. After a couple of weeks of bidding, I finally (by accident) won two nearly new sets. So I will be listing the extra set as soon as they get here to recoupe my money from the second auction.

Good luck~ Anthony

I installed V&H Duals, Stage 1 and Fuel Pak last weekend. Thursday went up and ran it on a dyno to see what changes the fuel pak made. I had ran my bike with stock setup two weeks before.
The bike runs okay but looks like terrible on the dyno, air/fuel is in high 18's at low speed tappering to 16's at high speed. Sent V&H an e-mail and called them along with sending them the dyno results.
I am now waiting for some positive feed back on what to do and any changes to make to Fuel Pak.

I have a 2008 FLSTN - Softail Deluxe
V & H Duals / quite baffles
SE Stage 1 cleaner
Fuel Pak 61001A using FP-677 settings


If anyone has had the smae issue I would like to hear from you or responce you got from V & H.

Hey thanks for the info. Do you have the hi-flow air cleaner too? Did you do anything to the EFI map? Any popping or backfiring?

Thanks,
RB

Yes, all detailed in my previous post. '08 Ultra with SE Stage I A/C, older discontinued pre-EPA SE Mufflers #64903-99, V&H Fuelpak, H-D Oil Cooler. Bike sounds great, zero popping, very smooth. I had V&H mufflers on my last bike and for me were way too loud, even with quiet baffles. Factory '08 Mufflers were so quiet I could not tell if the bike was running or not. Besides the sickly sound, the heat was unbearable! The SE mufflers I am using are right about inbetween and for me are perfect, but I am 50 and want to be able to hear the bike when it is running, and hear my wife/stereo on the intercom. What I am using is perfect and easy to tune. I will be selling the extra set on ebay next week due to the fact that I accidently won two auctions for them. Supposed to be like new 10 out of 10 like the ones I am running with only 500 miles on them.

My desire was to get some quality sound but not end up loud like on my last bike, get the heat out of the engine (live & ride in extreme desert heat), and increase performance just a bit with NO POPPING. All other aftermarket muffs are just way too loud for me, and I had heard them all.

Last weekend we made a quick 600 mile round trip ride over to Phoenix Arizona & back and the bike runs perfect. Most of the trip was with the cruise set at 80 mph on Intersate 10, and double up with overnight stuff & plenty of water packed we averaged just over 40 mpg.

Now have enough miles (1,000) to drop all lube and refill with Amsoil. Just like on my '07 Dyna, I am expecting another drop in operating temperature and slightly better mileage after the change out.

Cheers~ AV

Hi.

It is most likely an issue with how your tuner ran the bike on the dyno.
Mine showed a very lean burst inb the first part of the run, but that was from him running it like how they do a Harley SERT.
The Fuelpak shunts the injectors on decel, most likely he ran it up, the decelled it to start the run, well if theres no fuel flow just before he runs it up, it will have a lean burst on the run.
You need to let him know this, have him hold speed for 5 seconds, then do the run.
Then you will get a far more accurate picture of how it is running.

Thanks for the information, Jeffy Tune. I sent the results from two dyno runs to V & H. Had two friends run their bikes too and they both look good.
Both front and rear start off at 18+:1 ratio and and top end level out to 16+:1. I thought it may be exhaust leak on one of they cylinders, except both runs look identical.
I have been talking with V & H trying to get this problem resolved before I go on any long rides. Just can't take a chance breaking down on the road, South Korea is not that easy to get road assistance for a Harley even though there are alot of Koreans riding, most Road Kings here.
Once I get some positive feedback from V & H I will post the information.

Hi, I would first like to say this has to be the greatest thing i've seen on the internet for a long time. Second, I would like to commend Jeffylube on his time & respones he has put into this forum. Its nice to know that are guys like that willing to help a bunch of strangers.
Ok, Now im riding an 06 Dyna super glide custom six speed fuel injected, Speeds high performance air cleaner and vance & hines big radius pipes w/ fuelpak.
Now for the first couple hundred mile It ran almost flawless with a couple decel pops here & there but i could live with, But here recently after spending 125 on an oil change im seeing some changes. I get more pops on the decel & a hestitation (weezying sound as i can best describe it) ocassionaly when i give it gas, sometime when i first take i get a hestitation as well (like a cold morning start with a carbed engine again as i can best describe it) im getting worried. Any ideas...Also how would i check for maybe a vacuum leak. Then I have heard a couple discussions about maybe changing from 8 degree injectors to 25 degree injectors whats your thoughts on that. One last thing how does removing the baffles effect performance good or bad. I hope you guys can help thanks again even if you cant & keep up the great work.

2007 FXD Super Glide, Stock motor & ECM, Big Sucker, Big Radius w/ Standard baffles and Nightrider XiED's.
I added a Fuelpack Ver 12 using FP-0597 mapping.

I asked V&H about leaving the XiED's and adding the Fuelpak, they said "NO" If I add the Fuelpak I need to remove the XiED's.
I asked Stephen/Nightrider about any known compatibility issues and he said there are many riders that are using both with great results, they seem to complement each other.
In my case it ran great with the XiED's, and it runs even better with XiED's and the Fuelpak. I'll be leaving them both.
My MPG was 46 with only the XiED's so time will tell what the Fuelpak does to my mileage.

Hi.

Ok, It sounds like to me that you have a lean run going on. When you change out the dirty oil, that oil have blow by in it (Blow by is the gas and air that gets past the rings) because the old oil had some gas in it, it was helping it run better, clean oil removes that at first, so a lean run looses it crutch, and gets worse.

So the question becomes, what changed.
Well, for one, the gasoline we are getting of late is not the best, there skimping on the additives and maybe adding more alcohol.

But I would look first at the intake seals, it's a very common issue with Harley's, the intake seals suck in, and lets air in, leaning the mix out.

Take a can of WD-40, let the bike Idle, and carefully with the extension stick in the nozzle, lightly spray the area on the head were the intake come in, and look for white smoke or a change in the idle speed.
If it does, you have a leak, and the seals need to be replaced.

Is it that you downshift, decell then jump on it?

Is it like a cough, a dead bog then goes or does it buck a couple times then go?
Let me know, and i will try to help you further.

Hey, Jeffytune!

I don't know about Chris's problem, but you called mine PERFECTLY!
I have an 08 FLSTSB (CrossBones Softail) & after the V&H Big (Black of course!) Radius, stage 1 EFI kit & the FP, her symptoms are EXACTLY as you described...BUT it only does it within the first 1/2 mile...
I talked to Adam & he told me to reset #23 from 16 to 17....
Now she rumbles & stumbles WORSE...This AM it went on for
about the first 2 miles...
I see from a couple of other VTFers that they were instructed to change #23 from 16 to 50...
Was I misdirected?

I have a 06 fatboy with a fat cat exhaust and se intake. I was running a pc III usb when it decided to holding the map. Took it in to the dealer to see about refund, replacement told that pc are only warantied for one year (had mine just over a year figures). Planning on doing some more engine work so i was not to thrilled about going back to a product that has already failed me. A friend had an extra fuel pak laying around not being used, so took it to the dealer to install (already at that point paid max for dyno time cause of the pc failure wasnt figured out right away). They dyno tuned it. I feel that it runs just as good with the fuel pak as it did with the pc III usb. Only wish there was a computer hook up. Doesnt have all the bells and whistles that the pc has but for the price and ease of use great product. V&H are good to work with as well, atleast compared to dyno jet.
