how to make my bike leaner

[Danthemannn]

Hi, hope i am in the right forum...

Last week i bought a Deluxe EFI 2005, stock beside a pair of Rinehart slip-ons...

The bike was located at 120 miles from my home when i bought it, so I deceided to ride home at 60 mph to see what was the fuel consomption.
When I arrive home I fueled back the bike an did the calculation. The bike gave me only 47 miles to the gallon, You might says that it is good , but don't forget, fellow american, that I am canadian and our gallon are a bit bigger than yours, and beside that, my beloved fat boy 2003 (that was stolen 2 weeks earlier) carburator, se204 cams, 210 main jet, khrome werks 3,0 inches slip-ons and screaming eagle adjustable ignition at the same speed for a long ride was giving me around 61-63 miles to the gallon.. On dyno the fat boy was giving me 72 horses and 84 pound of torque

So the Deluxe (mine) is running alot richer than my fat boy...
I have changed the spark plug to find out that the old one were very very black, I changed them for Harley plugs triple platinum since no one seem to have NGK iridium on hand in my region.

Yesterday I went to see a Dyno guy at 80 miles from my home,
put the bike on the dyno, after 4 runs, 69 horses, and 80 pound of torque. Very good if i compare it to my fat boy. The computer graph also shows that the bike was running rich but not too much. Just after the dyno guy told me that he cannot do nothing whitout a power commander... (true or false ????)

Like he didn't have one on hand (power commandr for softail), and that I wasn't ready to spring $600 at the moment for the unit, installation and dyno time, I back off.

Now the question...
Is there a way I can make my bike leaner, so I can reach about the same mileage to the gallon, whitout having to buy a power commander.

Please remember that here in quebec we are the one that pay the most for gas in north america, and that most of the times I am doing long ride, so every miles count...

I also want to install a se-204 cams like in my fat boy, the bike was pulling like a tractor and I like that feeling... And then, if I need a power commander I will buy one and have the bike dynoed, but not for now...

The HD download don't help much, if you want the best bang for the buck the hot ticket is the TTS Master Tune..

Your gas maileage comes from what you program into the tables, you have to remember the TTS Tuner IS the SERT with more bells and whistles...(better calibrations too)

Give Doc or Dave a call or email them...Both are TTS Master Tune Dealers...

Please correct me if I'm wrong here...

But if you are using British Imperial Gallons (in Quebec?? Say it 'aint so!) the conversion calculation puts you at 39.1 MPG US Gallons. It does look a little rich at 60 mph. I get 39-40 MPG (USGallons) running steady 75+/- statute MPH. The black plugs might be telling a story...

Just my 2¢

Sounds like and looks like someone did something to your ECM for more fuel when they added the pipes. Do you have a SE air filter kit or some other kind of free flowing intake on the bike or is it stock? If it is stock install a SE filter kit...this will lean out your mixture but I can't promise it will be enough.
When you add the cam you will need a good Tuner and the best on the market is the TTST....this tuner will also let you dial in your own tune with the V-Tuner Program in the software, it won't be as broad as a good dyno tune nevertheless it will be good where you ride.
I offer the Forum members a 10% discount on the TTST, if you are interested PM me.
The AFR you seen during the Dyno run was at 100% throttle, this area is normally pretty close on most downloads, but you didn't ride your bike home at 100%.....where you rode is about 8% to 12% throttle and it looks like it is very rich in that area to blacken your plugs.
Try the air filter first and see what she does.

[Gulfstream]

I have to agree with Doc, something must have been done or added to the ECM to get it that rich. Have you cheecked it over good for a piggyback unit of some sort? Also, some 05's had bad valve seals and they will blacken the plugs to make them look as if they're running rich. As Doc said, a free flowing air cleaner will help it lean out too so that may help. Good luck!

[Danthemannn]

Yes, to answer HDM 88 and Gulfstream... 2 days ago I did install a SE heavy breather on the bike in hope that it will make it leaner, but this installation didn,t improve nothing if a miles or two better per gallon.

And also yes to plongosn, I did my calculation (MPG) in british imperial gallon, so you right saying 39 miles to the gallon if it was claculated in U.S. gallon...

And also something I forgot to mention is, when I did change the spark plug to new HD plugs, I did notice that the stock air cleaner was very very dirty, so I thought it might be the problem, so that why I order a heavy breather hoping for better result... but no luck or 2 miles per gallon is all I might expect...

thank for the support...

[plongson]

I can't imagine a tuner running a dyno on a bike with a very dirty AC...What was he thinking?

In that case you need a tuner and like I said the TTST (MasterTuner) is the best on the market today.

[aka_matt]

slightly off topic, but the hp/tq numbers are very close to the fatboys, which had a cam... are you sure the new bike isn't cammed also?? was the fatboy an 88" or 95"? is the new bike an 88" or 95"?? just wondering...

[Danthemannn]

Both bike were (is) 88 inches, and I did have the heavy breather when I saw the tuner yesterday...

And while I know that the fat boy was cammed, the previous owner of the deluxe (he was the second owner, and I am the third owner) didn,t know zip about the first owner, and I didn't open it yet to check... But one thing I can tell you is that : this bike really fly after 70 mph. So maybe there is some kind of a small cam !!!

V-Tune won't work with his bike.

just arrived from a sunday afternoon ride.

I did almost 185 kms or115 miles at or around 60 mph...
And yes again 2 on the bike (me and the wife) and after fueling again I did average the same as before 45 mpg (canadian gallon)

When I got home I noticed that each side of the throttle body where are located the two breather that were plugged into the stock air filter, that are now plugged with the big chromed plug cover, there was small line of oil coming out from the two cover plug...

Is that normal or should I change the o-rings for some with a bit bigger diameter to make a better seal????

Thank again
Danthemannn

And yes after the cams I will need somekind of SERT or TTST or whatever it might be called but I dont know yet which to choose, because there are no oxygen sensor on my bike and if I could install one (power commander) whithout having to drill the exaust pipes for installation, that would be my first choice...

Thank again...
