Injector cleaners ok for bikes?

Discussion in 'Maintenance and Servicing' at netrider.net.au started by justin_es, Jul 20, 2014.

  1. Good day people.
    Just like the title suggests.
    Injector cleaners on bikes?
    Are they safe?
    Are they worth doing?
    My fuel tank looks clean as a whistle and I never see anything floating around but doesn't mean its always been that way and the injectors might benefit from a little clean out.

    Didn't want to just go ahead and throw it in and it turns out to be a bad idea.

    Please let me know.
    Cheers guys.
  2. was ok for me when I used it. after I put them in the tank it seemed stabilizing idle which had had unstable idle speed up and down.

    In addition, my bike is running with carburetors, not injectors.
  3. i didn't think it would be any different to a car.
    Just need to get the mix right.
    1 bottle normally does 80L so ill put 1/4 of it in my bike the rest in the car i guess haha
  4. The residue left by fuel is like a varnish. Modern fuels have a detergent additive to help with this but no one seems to want to tell you what it is or how strong. My only concern with DIY injector cleaners that you add to the tank is their strength and the effect it may have on injection components over time. Indeed I'm not convinced they work at all.
    The only sure way is to remove the injectors and have them cleaned in a specialist injector cleaner, the down side is the labour cost component. The up side is that you know they have actually been cleaned.
    Others may have a different view.

  5. I understand exactly what your saying mate. And I must admit I have never once thought hmm that definitely made a difference.
    Only ever bought a hand full in my driving life. Cant justify the $$$ without seeing any results.

    I think it's more that the claims are there so usually every vehicle I get when I first buy it gets 1 bottle just in case it really does make a difference.
    This usually coincides with a full service when I first buy the vehicle also.
  6. I thought most injector cleaners were just stuff like toluene or kero and some shorter chain hydrocarbons?

    eg http://www.wynns.net/pdf/msds/77218-Petrol-Injector-Cleaner-MSDS.pdf
    fuel oil, No. 2 None >60%
    naphtha petroleum, light aromatic solvent <10%
    other non- hazardous ingredients <10%

    not necessarily that different to normal petrol... but maybe some lighter or better solvent hydrocarbons, and maybe some alcohols too??

    safe? should be.. petrol is..
    worth it? mayyyyyybe
  7. I'd be a bit cautious if you have a plastic fuel tank. Apparently just the ethanol in E10 can damage those tanks.
  8. Do you have any reason to think your injectors are blocked up? In my experience the whole injector cleaning is the thing the mechanic uses to pull one over on the unsuspecting/ mechanically inept customer just to get another couple of hundred bucks out of them
  9. No its running fine.
    Well seems to be anyway.
    Like I said before its more a thing that I do when I give the new vehicle a full service when I first buy them. Considered same practice with the bike but yeah re considering.
  10. Ok but 10% is a substantial percentage of volume and Non Hazardous relates to human health not engine components, who knows it could be laundry detergent, they aren't going to tell you. I'm still sceptical about something has little to substantiate its effectiveness and nothing to guarantee it has no negative effects.
    But hey, you want to use it then do so.
  11. My mechanic puts some in every time he services the bike (well it appears on the bill anyway). Guy that does our cars does the same thing.
  12. If bike is running fine then I would not waste my money on fuel system cleaners. Money is better spent using quality fuels instead. If you are wanting to give the fuel system a check over on a newly purchased bike, then I'd recommend draining tank, removing fuel pump and back flushing its pre filter, and while pump is out have a good look around in tank with a torch, or just give it a flush out. You never know what garbage the previous owner has put in the tank.

  13. Yes and No, better explanation then my words can be placed in the video..

    E10, is good at doing the same thing also, if your transport is compatible.. as stated above.. Not to be used if you have plastics in the line, as it can break down over time.
    But if your metal or rubber all the way clean sailing.. but most are not with the filters being the issue on Bikes.
  14. Another vote for the occasional E10 tank. I found it would clean up troublesome carbies.

    and even if your fuel line materials are not compatible, the odd tank is going to make bugger all difference.
  15. I've read some interesting studies on the effects of short chain alcohols on aluminium oxide.
  16. Seen it work amazingly well on older mistreated automobiles.

    From having next to no power to almost back to factory specs, so it should have a similar effect to a bike with build up, just from using e10.
  17. My current bike looked like it'd spent a lot of time sitting around, so the first couple of tankfuls got treated with Techron 5000 fuel system cleaner (dosage adjusted for tank capacity, worked out to about 1/4 cup per tank for me).

    Hasn't seemed to hurt any. It's sold at Caltex, apparently it's the stuff they use in Vortex 98 but obviously a lot more concentrated.

    I once loaned my Z750 to my brother who, not knowing any better, filled it with E10 a couple of times. Put another 30000km on it before I sold it, never had a problem. Still, the Kawasaki advice at the time was not to use ethanol so I fed it nothing but petrol when I got it back.
