What's involved in cleaning the fuel injectors?

Hey ,

I am coming up on my 4000 mile service, and I have done oil filter changes, oil changes and screw tightening, Chain cleaning and adjusting, but never messed with fuel injectors. The dealor quoted me 300 for all that, which is a little much !

So, what is involved in cleaning the fuel injectors?

Thanks,
MW

Maybe it's because I use top tier gas whenever possible, but I've never had an injector problem on any vehicle. Just say no unless you have a running problem. http://www.toptiergas.com/
http://www.rowand.net/Shop/Tech/DIYF...orCleaning.htm shows the process.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

Most services clean fuel injectors "on vehicle" which essentially consists of bypassing the rest of the fuel system, and then hooking up a pump which runs solvents through the injectors to clean out any deposits. Some will do "off vehicle" cleaning, where they remove the injectors and put the in a machine that pumps the solvents through the injectors combined with ultrasonic vibrations. It's doubtful that most motorcycle shops would have the machine for "off vehicle" cleaning.

Worst case, some shysters will simply dump some Gumout in your fuel tank and charge you for "fuel injector cleaning." It's best to ask you shop specifically what they do. If htey are't willing to explain it to you, go find another shop.

Save your money. It is highly unlikely you have a problem with your fuel injectors needing to be cleaned...

Worse case, run some techron thru it on a full tank ride.

Proposed Injector Cleaning

As a career professional mechanic I can safely say that 99% of injector cleaning operations are a complete waste of time and money. Just use clean fuel always and change fuel filter as specified in owners manual.IMHO

Okay - maybe I'll go with option 2 then...

Option 2 being to order the V manual online, Get the oil, new filters, and change them myself.

It would be convenient to pay the guys to do it. But $305 is too steep. I will have them do the valve check though someday.

And It happens that I do get gas at the local Texaco (with Techron) station. Maybe I'll also make it a practice to only put high octane in it.

Thanks guys, good advice...!

I have to run 90 octane or higher in my C14, so besides looking for top tier stations, I also avoid pumps that don't have seperate hoses for the octanes. And whether it is needed or not, I still like to drop in some Techron a few times a year.

Am I confused?

Is the dealer suggesting you need your injectors serviced or are you thinking it needs to be done?

At 4,000 miles?

Never been an issue. I do use some pour-in cleaner 2 or 3 times a year just "because".

The multiple references to Techron as an additive cleaner -- it's the first time I've seen on this forum or anywhere else the emphasis on that particular product. Is there a new study that I haven't seen as far as effectiveness is concerned? Did Sea Foam, for instance, lose its flavor on the bedpost overnight?
