  • Anybody else tried the various snake oils being sold by Liqui Moly?

    The XJ600 hasn’t had a carb clean in forever, certainly not in the >4k miles I’ve put on it since March, possibly never in the 13k it had on the clock before me. There was definitely rust in the tank and I have definitely not bothered to strip it and be without the bike for a fortnight to do a molasses/vinegar/whatever treatment. Plan has been to do it sooner than later, sort the tank then clean the carbs properly.

    In the mean time it’s run only V-Power, unless I’m caught refuelling away from Shell. I was warned against using Redex, there was anecdotal evidence of it glazing carb surfaces if nothing else.

    I did, however, use some. It seemed to shift the deposit I could see in the in-line filter. There’s always been a bit of a stutter in the rev range that seemed like a partially clogged jet. It was consistent - one gear higher than necessary, cruise at low revs, crack the throttle to accelerate, get a gurgle. After a bottle of Redex that has got a lot better.

    At a preferred moto gear outlet today I bought the 4T fuel system cleaner shot thing, 80ml of Liqui Moly placebo. I was 60 miles into the fresh full tank and had the same distance home.

    The way home the bike seemed a lot more lively and responsive. Revs picked up faster and it stopped feeling like an unloved 25 year old bike.

    So, am I the only one stupid enough to waste money on miracle cures? Or am I the only one who felt a noticeable difference?

  • I've never had any luck with the carb cleaning magic juices - not tried that one though.
    Citric acid works a treat on tanks and is cheap - doesn't need much more than overnight.

  • Yea, I always assumed they were bad money spent to make the lazy feel like alchemists.

    It made the XJ feel like the little engine that could, so it definitely helped shift something.

    Citric acid sounds like a winner then. Might loom into that.
