Had my fuel injectors ultrasonically cleaned!

I snapped a couple of pics as I was wrapping it up. I didn't see a need to do a "how to" as most of the cheap asses here will not brave the depths of this particular procedure. In all reality, this is pretty easy to do.

In a nutshell:

Pull the tank (or lift it)
Pull the airbox
Remove the two screws that hold the fuel rail in
Unplug the injectors
Remove injectors

Seriously. That's it. Clean them off, put them in a bag, and mail them off. A few days later you will get them back sparkling clean with a sheet that will lay out the numbers. I was very surprised when I got my sheet back, the difference in flow before and after is pretty high. I will put the bike on a dyno when I can to compensate for the addition flow. I have 17K+ on my bike and run 87 octane fuel for those that might wonder.

Here are some pics:

Looks like a good idea to me after I've accumulated 30-40 K on the bike. It's not expensive, but looks like it takes a while to get them off and back in place. How long did it take you to get them off, in the bags and off to the company? Or, did you deliver yourself? I guess I'd do it in late fall/early summer so I didn't have to give up riding in nice weather here.
 
Wow! That is very surprising that they were that dirty in only 17k miles.

Their prices seem very reasonable and I am sure if you're willing to pay overnight shipping both ways the bike will only be down a few days, but it will add to the cost. For those of us that actually have a Winter and don't ride for a few months I guess that would be the time to do it.

Just curious JD...did you ever run a bottle through your tank of any of the good fuel injector cleaners like Techron? Wondering how much they really help...
 
Getting them out is much eaiser than I thought it would be. The fuel rail holds them in, and the fuel rail is only held in by 2 screws. That's it. You just have to yank the airbox to get a clear shot at the two screws, and that's very simple to remove. Shipping is cheap, and they generally have a 1-2 day turn around. I mailed them out since shipping is cheaper than fuel to their location. I have never used an automotive fuel system cleaner in a motorcycle...just don't really feel comfortable doing it.
 
No rain right at this moment, but it's 100 degrees outside. If anything, the bike should be slower as it should be richer now. I will put it on the dyno after I get back from vacation too see if we need to tweak the map for the extra fuel flow.

Seat of the pants on a near 9 second bike....naaaaa!
 
Hey you mention that you simply remove the fuel rail.
I thought EFI fuel systems were high pressure even when turned off, and that you needed to relieve the pressure first before touching any fuel related bits ? Or is that only applicable to cars?

Any FI system is going to have a lot higher pressure than a carbureted setup, whether it's motorcycle or automotive related. I know JD didn't mention it, but I am sure he relieved the pressure before taking it apart, otherwise he probably made quite a mess...

nice setup. Never heard of cleaning injectors that way. Curious to hear those dyno numbers.

Hey Dave! I'm still running a set of your old flies. Dyno numbers will hopefully be soon, just busy with work and such and fresh tuning has taken a back seat. Should be done in the next 1-3 months though.
 
JD, what kind of gas are you using? I'm not sure what diff it makes, but after EPA drastically dropped requirements for detergents in gas, some car companies invented a new standard, called Top Tier, that meet a higher standard. The companies they list that meet these standards for detergent in all of their fuels, regardless of octane ratings, are:
QuikTrip, Chevron, Texaco, MFA Oil Co., Conoco, Phillips 66, 76, Entec Stations, Shell, The Somerset Refinery, Inc., Kwik Trip / Kwik Star, Aloha Petroleum, Tri-Par Oil Co., Turkey Hill Minit Markets, Mileage Stations, Road Ranger, Chevron Canada, Shell Canada, Petro-Canada, Sunoco Canada
Other brands, apparently, may have much lower detergent content. Does anyone know if this makes a difference?
