Cleaning the Injectors

[Breeze7]

Morning All,

Can anyone recommend an liquid additive to put into the fuel tank to give the injectors a clean/flush out?
There seems to be lots on the market claiming this and that, but mainly say for car engines?

Why don't you just ask which tyres they recommend Breezy  their will be a thousand choices. You'd be better off heading to Supercheap or the like and asking the same question.

It says on car engines as the dosing instructions are for car's petrol tank size. Adjust the dosing for your size tank and you are good.

I used injection cleaner (Liqui Moly). The can was good for 3 applications to the 22 liter tank.

However, I don't use it anymore. Had my injectors professionally cleaned and after that use premium petrol which claims having an additive in there that helps keep 'em clean. Money-wise it's about the same for me than treating the 14 once a year with injection cleaner and has the added advantage of containing no ethanol.

Car or bike engine doesn't matter, they are all the same. Just lob some in according to how much the tank holds as said.

I tend to throw the redex injection cleaner in occasionally, because the local cash n carry does it cheap. One bottle says 50-60ltrs, so I make it last two or three tanks. I'm not convinced it does a huge amount but my bike runs sweet so maybe it's helped over the years.

Run a few tanks of Shell V-Power through, the additives will clean the injectors. I ran my 14 on V-Power or BP Ultimate as whilst it didn't need the higher octane, over time it kept the injectors clean and made it run a lot smoother.

I've never used anything but 98ron fuel in all my bikes wether it specifies it or not for that reason of cleaning the injection system and burning any deposits off the back of the valves. I avoid Shell as the detergent they use in Australia has particles too large for motorcycle injectors and some times causes clogging.

That sounds strange Chris, you'd assume Shell would have thought of motorcycles as well.  I xdidn't know our injectors were so different.

[GSXKING]

Motorcycle injectors are smaller than majority of cars Col 

[KiwiCol]

yeah, but there's a lot under 1402

[Andre]

Size of the injector shouldn't matter. Clearances within the injector do. General consensus I found on the net is that no particles greater than 10 microns should be allowed to get to the injectors. Some (modern) systems require 5 microns. That's the job of the high pressure filter. I have no idea about the filtering size of the little filters within the injectors.

Would be interesting to know the size of the Shell detergents. I am not going to put Shell (V-Power) in mine as it is by far the most expensive here and not ethanol free (in Germany at least).

Thanks all for the information

For your info details in recommended suppliers section here .
I've used this company and great results at a very good price when I had a clocked injector.

I use the Penrite injector cleaner for petrol from Supercheap Auto in mine about once a year, dosage for a full tank of fuel, and always run on 98RON, usuallly BP ultimate.  Never had any problems.

Ive been adding acetone to my bikes for years and never had an issue with injectors or carbs (except the bandit  )

Do the additives clean the injector nozzles and the filters.
