Fuel-X Lite Install

[2LZ]

I'll have to locate this "document tray". I need a spot to stash two resistors for my LED blinkers.

Here's a shot of my FuelXLite chilling in the tray (after removing the lid) to give you an idea where it is.

Try removing the Seat, the document tray is there somewhere.

Found it today. Been working back there under the seat for a while. Feel like a dork for missing it......

Yeah this thread has been very helpful so far. Just installed the FuelX lite this morning, also placed in the document tray that I otherwise no doubt would have missed .

However the orignal cap that covered the tray doesn't seem to be big enough to cover the FuelX so I've left it off completely, just wondering if you did the same or that you found a way to put the cover over it?

Nice install, what does your butt Dyno tell you?

I ended up not using the document tray and put it on the flat spot above it under the seat.
Regarding results, I did a lot of mods around the same time and they all helped "a little". Unfortunately, nothing was like bolting on a turbo.
The best way I can explain the Fuel X Lite result was like rejetting a carb to the proper pilot jet and getting the needle clip in the correct position. Not dramatic, but felt healthier. I definitely noticed a drop in MPG, but again, I did a lot of mods within the same two weeks.

I did the first drive today, and I must say I am very happy with the results!
No doubt this came from correct expectations (mostly from the reviews at the TEC website). So there are no huge changes in power or even acceleration.

But the difference, even though it is subtle, is at the same time remarkable and immediately clear. Even for a friend who only rode my bike a couple of times. The engine runs 'calmer' both at lower and higher speeds; when your are in lower revs in a low gear, there is almost no 'jerkiness' anymore (before I would often engage the clutch to get it up to speed again, there is much less need for that now). The ride feels smoother. But it still feels familiar. In a way it feels like this should have been the way for the Himalayan to have come out of the factory.

Too soon to say anything about mileage, but with the results so far I wouldn't care that much, this difference is so worthwhile.

Yes, I bet the factory wishes this also. Unfortunately, there are Euro, EPA and CARB regs that need to be met. Everything is jetted/mapped very lean to meet these regs.
Proper jetting (on a carb) and remapping brings out "what should have been".
I'm glad you liked the results. I'm pretty darn happy with my Scram now, as well. Still weighing out the cam though. Costly. I bought a pair of racing cams for my DRZ for less than the cost on one 411 cam. For the cost, I'm going to truly want to see a difference in power delivery.

I am on the fence about the TEC Cam as well. It's mostly that I will not be able to do the installation myself, and paying a mechanic for it seems to triple the expenses at least. The cam itself is reasonably priced.

But from my experience with the FuelX being in line with other reviews, I'm now pretty confident that the cam upgrade is legit and expect that I will love the bike after that. So more and more inclined to bite the bullet...

Definitely. If I didn't do all my own work, this would have added an entirely new expense to the situation. I'm sure I'll end up caving in. I'm simply a mod freak and the cam is the last one left. If I can get it to wake up just a bit more above mid-range, it would be a nice upgrade.

I hope I am not diluting this thread, but regarding the Cam install, it is not a complex task but doing so raises the subject of "dialing in" the Cam as would be the case if done correctly.
Unfortunately we do not have the ability to do this on the 411 engine so results vary as has been shown by posts.

 

[Ike208]

Bridging the gap between the two subjects: do folks think the FuelX Lite has enough "smarts" for a cam upgrade on its own? Or will there still need to be ECU-flashing and mapping done?

So an update on the FuelX lite; after being very positive initially it now seems that the bike is plagued with starting issues in colder weather, with winter just around the corner.

I'm not sure it's the weather, or the cam, or something else (maybe another malfunctioning relay like before), but it now usually takes several tries to get the bike started, and two times after driving a couple meters it just stalled /shut off when in 2nd gear, and needed to stop and get it started again. Anyone else notice this after the FuelX install, or does it sound like something unrelated?

Then once it's running for a while it seems to be fine but it's still annoying that it doesn't feel reliable.

I've noticed no difference with mine, but we've only got down into the 30's, so far.
Tight valves is often the cause of starting issues. Have you checked them recently?

Now that you have had the FuelX Lite for a bit, have you seen any issues develop? On the fence about ordering it, all I have so far is the Powerage slip-on and the bike is running great and starts perfectly every single time (what a change from my old '21 Himi!) When I tried the Booster Plug on the Himi, it worked for about a gas tank before (I'm assuming) the long-term trims were adjusted and it became a fashion accessory...

All I really want is to enrich the mixture up a bit, gets pretty hot and muggy here in the Carolinas in the summer.

Not that I've ridden it much the last few months, but I've noticed no problems starting. I fire the herd about every week in the Winter and let them run for a few.
I've found no issues with the Fuel-X Lite at all. Just the "slight improvement" like all the mods. I have a Fuel-X Lite for my Interceptor on the bench I'll be installing when it gets warmer. No real regrets. I'd probably regret it more not having it, as I'd be bummed about what I may be missing.

If you fit a Cam then the Fuelx is a must. IMO

I fitted the cam last week, and you have convinced me to get a fuelx, no point in doing half a job!

 

[Overdrive]

I ran around for over a year with a tec cam and no fuel X. Big mistake, as although the engine was better over 4k ish rpm, it did feel a bit flat below this - I guess I just got used to it.
The fuel X was a revelation, all the bottom end power returned, and although it always ran reasonably cleanly, it is far better at low revs, c3k. An essential part of a can change imo, and well worth the money. (E5)

Well done you! It is not easy to entice a Yorkshireman to part with cash!!
