anyone ever disappointed after swapping cams?
The bike runs good, now, and I am fully aware you have to "pay to play" but this just wont work for how I ride.

I have 2017 street glide special with a 107 and it has been my main touring machine since 2017. But over the winter I decided I should have a look at the oil pump and install the updated one, and while I was in there it would be a good time to put a cam in.
after some research I settled on the 22xe.
once completed and we finally got some warm dry weather up here, I found the "can tune" from Fuel moto wasn't gong to work for my bike. so off to the dyno for a proper tune.
but now I find I have terrible fuel range.... 250-260km (150mi)per tank. the norm was 350km (210mi) pre cam install.
I've been back to the tuner to see if we could safely pull some full from the cruising area, and saw no real benefit.

being as I never really had an issue with the power before, I am very close to putting the oem cam back in. looks like I spent allot of money for nothing. :cry:
really wish I had left it alone.

I actually had my dealer do the install.
I have a deal through them for life time oil change. They do it every 4000km for as long as I own this bike. So I choose to support them when I can.
So I had the cam done with a major service. It's sucks that I wasted all that money but I think I'm giving up on it.
To make things worse, the oil pump looked like it was brand new! I didn't need to worry about any of it. I should have known, it made it 88k with out issue.
I'll chalk it up to a life lesson....damn expensive one.
I've always been curious why those that actually use the bike a touring bike bother with performance upgrades if it diminishes the intended purpose of the bike.

I have modified every bike I've owned but this is the only one I've had a disappointing outcome. It's also the first Harley I've owned.

I guess stage 1 is going to be the sweet spot.

Fuel moto was a month getting back to me the first time. They are simply too busy this time of year, and my season is too short to wait.
The tuner I took it to used different software to tune it. So I ended up having to pay for more licenses. Not to mention that trusted tuner is a few hours away.

My time is simply too valuable to me to keep going.

I'd still end up taking a big loss.
I have no interest in a new bike or a used one that could bring someone elses problems. And I love that I never see another bike in Laguna orange!!!
I'm may swap the cam myself. Or if I let the dealer do it it's a 2.5hour job. I'm sure someone will buy the cam used at half the price of new.

Betts,
I purchased a tc 110 with SE cams and pistons installed. I was told (by a liar) it only had exhaust and air cleaner change. After a lifter broke, I changed it back to the hi torque SE 255 cams that came in the 110 as stock and stock compression pistons. Max. torque is now in the rpm range I ride in and I couldn't be happier. New cam bearings along with an OEM cam plate and OEM oil pump were also installed. TT master tune and a trip to the dyno rounded out the return to stage 1.

Your experience suggests to me that it is not the cam but rather the people you have working on the bike.

I know MANY people who run that cam or similar ones without that loss of fuel economy, myself included. I put the S&S 475C in my 2021 107, along with all the other bells and whistles, and added 15 ft lbs of tq or so with zero loss of fuel economy. I had my old Ultra built from a 96" to a 10.5:1 compression 107 with Wood cams. It added 40 ft lbs of torque and got better fuel mileage.

Also, guys add the power and then USE it. That burns fuel. But if you are the same guy, riding the same bike, down the same road, at the same speed, and it is burning 25% more fuel, it is not tuned correctly.

OP, you mention that you "never really had an issue with the power before" but you make no mention "if" or "Did" you get any power increase when changing to the new cam? I assume you did?
My thoughts have always been to get more power it will come with less MPG but if you had no want or no need for added torque or HP and MPG was the #1 goal my thought is that EPA friendly stock cam you had may very well be the cam for you?

However, with the cost of putting the stock cam back in how many miles or added MPG would it now take to recoup that cost of putting the stock back in with future savings at the pump?

Are you sure you will never needed the added power? Do you not like the sound and perhaps a better more fun riding experience of the new cam over stock?

A cam and exhaust is the very first thing I do to a bike as I love that added low end pull and the sound of a lumpy cam is music to my ears.

I have owned many a Harley and been riding 30 years and in those 30 years I could not even tell you what MPG any of my bikes got? I have no clue, no idea? I could care less as my brain just don't work that way, I'm not a rich man but my thought has always been If I can afford a Harley and I can afford to buy performamce I can afford the gas whatever the MPG is but hey thats me...

Also, even as a minimum wage 16 year old new driver MANY years ago I was never one then or to this day even look at posted gas prices. I always then and now buy my gas based on brand, quality as I will pay $1+ more per gallon for ethanol free gas for my bike and would actually pay whatever the gas station charges as long as its the best gas for my bike, car and truck... I know that may be strange for many but thats how I roll...

A lumpy cam and a V-twin ride always puts a smile on my face and makes for a fantastic day; MPG calculations, not so much...

I am aware you have to "pay to play".
the bike runs great, sounds great.
Yes there was an increase in power, bike made 117ftlbs and 106hp
did I need the power? no....who ever does? but it will make you smile every time.
I dont really calculate mpg on my bikes, I pay attention to my fuel range over all(yes its the same, I just dont do the math) .
I know if I spend the day in the higher RPM I will get less fuel range.
I didn't expect such an increase in fuel consumption. a 25% loss in my mind is unacceptable for a cam.
I have talked to the fine folk at FM and the made some suggestions.
as far as cost, fuel while fuel is usually more expensive on this side of the boarder its not my concern. Its proximity to fuel that has me thinking about going back.
Keep in mind this is all referencing riding the bike as a commuter, not even riding the bike in the fun zone..If I ride where the bike makes the most power , above 3500rmp, it drops to 230km a tank (138mi), or worse.

If touring a lot then mpg is important, I can't tell how many times I have found a station with 20 miles left in fuel. I did a stage 3 on my last bike, a Road Glide Ultra, and got 3 or 4 mpg better fuel mileage and a huge increase in power!! I did have the dealer install the stage 3 so I could keep the warranty. I traded that bike in on a Tri-Glide which is currently for sale. I picked up a very low mileage Heritage Classic which I will do a stage 1 . Going back to basics 😂!

I check my MPG on a reg basis, that tells me if there might be a problem. Stage 1, exhaust only as far as I know
If I am heading out I like to start with a full tank, fill up the bight b4
Its been steady since I bought the bike - around 43mpg - comes up as 215 mile to MT
When I headed out on the trip it wasn't about mpg, it was about making it the next destination/gas station
Most times no problems, but up in the Mountains I had 50 mte...and passed (at speed) what was the only gas station
Turned around, downhill into the parking area & pump, BIG SIGN- Out of Order, then an arrow back where I cam from GAS 25 miles
Another sign & arrow in direction I am going GAS 40 miles, I went for it, rolled in (downhill thru mts) 80 mte lol
Only other time I turned around was going to Salt Lake City, I turned off the Main route to avoid traffic, realized I needed gas

And out at some point the MTE went to over 50mpg, then 55mpg, and one tank to over 60mpg
Thought something was messed up, but the bike like Western gas & altitude
So for me it was about having enough gas to get to the next destination, not mpg
But travelling it was usually 3 hrs b4 I had to fill up/worry about getting gas
To cut that down to 2 hours would be a PIA

my season up here is really only 4 months. with a young family and full time work I do my best to get away with a buddy twice a year. I do well to get 15k on in the short season. so most of my rides are long multi day rides, with the occasional commute to work. I dont want to spend more time stopping for fuel. I make fun of a buddy who suffers from fuel anxiety, as in as soon as his dash says he has 100km to empty he is looking for fuel. the other day I found myself worried about fuel,

on another note, I did hear back from Fuel Moto and they are trying to work with me on it. so we will see where that goes. I spoke to them on the phone and they didnt think that the fuel consumption should have changed much....providing i can stay out of the throttle.
