EV14 Injector Kit Sale


Lowndes

Recommended Posts

I saw that Injector Rehab is running their Annual Black Friday 15% Off Sale until Sunday, Nov 28, 2021, on the EV14 Injector Upgrade Kits for 1100xx and 1150xx oilheads.  

These links say for the 1100GS and 1150GS but that's a typo, the sites explain it.  These kits include new injectors that have been flow tested and matched.

Injector Rehab is in Blackwood, NJ, and is owned and run by Keith Gibbons who knows a few things about fuel injection, is VERY helpful, and is a good guy, too.

 

For those that are considering this simple, plug-and-play upgrade, all you need is one eye, half sense, and a hex key.  Heck, I don't even qualify but managed to do it on the RT and S, even managed to do it on the old K where it's technically not possible but did it anyway.

Will these work with a Techlusion or AF-XiED?

 

Yes, they will. 

 

I have these installed with AF-XIED's on three different bikes, R1100S, R1100RT, and a K1200RS.  The difference is - 1) spray pattern, the OEM injectors are old design, one-hole units that make a "squirt" of fuel, and 2) reaction time - the EV14's are faster (smaller, lighter valve components react quicker).

 

The EV14's are newer, smaller, faster acting, four-hole injectors that produce a "mist" of fuel into the intake - much finer droplets, better burn.  If there is any difference in the amount of fuel one type delivers compared to another, the O2 sensor will signal the ECU to correct it.  The AF-XIED just alters the O2 signal to make any injector deliver a tiny bit more fuel to get the air/fuel ratio (closer) to optimum.  

 

It's easy to see the difference yourself.  Pull an injector out of the TB, leave the fuel line and electrical plug connected, put the tip of the injector in a clear bottle (glass or plastic - pop bottles work well), and press the starter button.  You will see the spray patterns in the bottle.  Just don't burn anything down.  NO flames or sparks.

I had an AF-XIED installed prior and it's function hasn't changed.  Immediate noticeable result after installation of the injectors was a smoothing out of the off/on throttle transition, much less abrupt.

I don't think there are any downsides.  Fuel mileage might improve slightly.  The single most noticeable change on my bike was the off/on throttle transition.  The original injectors would abruptly turn "on" when cracking the throttle to accelerate making the transition abrupt.  Not a help when you are trying to be smooth.  The downside on my bike (R1100S) with a Remus system is that it lost a lot of the popping, farting, crackling that I liked to hear, call it "character".

The benefits are all around better performance, and, if your injectors weren't matched (have the same fuel flow at all flow rates) much smoother idle.

 

The downside is that you will be $150 - $200 lighter.

Thanks Duck. Did they improve the on/off throttle transition? I wouldn't expect it to but thought I'd ask. Thanks. Miguel .

Thanks Lowndes. When you say "performance", I presume you mean acceleration and torque. I'm not unhappy with my R11RT's performance but it's always fun to get a bit more. Did you have to adjust/resync throttle bodies and/or reset the ECU by removing the fuse? Thanks! Miguel

I don't think there is any improvement in full throttle performance, but part throttle is smoother and crisper without being snatchy.

There isn't any need to synch throttles or re-learn for the computer.  I synched the throttles just because I am like that and it's easy on the S. 

If you are happy with what your bike is doing, the upgrade would probably not do much for you, but you'll never know for sure unless you go for it.

I was just riding around the issues on my bike and really didn't realize the improvement until I installed them.  I do recommend this, especially if you have big miles on your system.  My S had only 19,000 miles on it when I did the swap and there was definite improvement.  It's your money, though.  I was in the mood to throw some cash at the bike and it turned out great.

Thanks Duck. Based on the inputs, I'm going to pass on the upgrade. Like I said, I'm not unhappy with my current performance and I'd rather be out riding than wrenching anyway.

 

Cheers! Miguel

I recently fitted a set of upgraded injectors, the one with 12 holes in from a guy in Romania. They were supposed to cure the off idle stumble that has always plagued my bike, but they didn't. What they did do was make everything smoother, and I often reached for another gear to find I was already in top and going faster than expected. 

I have no idea what injectors they are, apart from being Bosch, but the down side was they increased fuel consumption. I don't ride hard enough to appreciate any performance increase, so I've now taken them out. 

 

I'm in the UK and my bike doesn't have an O2 sensor, so the Motronic can't diagnose or correct any increased fuelling.

In my never-ending quest to spend money on this bike that I don't need to, I went to install the new IR injectors, only to find 4-holed ones that were already there. I have no idea as to the quality of them, but here is a reference point for some:

Hell's bells, might as well put new one
s in. The blue 'pants' O-ring seems a bit large for the throttle body hole. I saw in another thread that freezing the pants with some teflon lube might work. Any other ideas?

The new, big "O-rings" between the adapter and the TB (and fuel tube to injector) are a very tight fit for sure.  Just rare-back and don't take no for an answer.  Warm them first if you need to, use a "twisting motion", and use your best "words of encouragement".

Growled at it.....

*Might* seem a little better, but the wallet might be talking to the butt-dyno to make itself feel better.
