    dropping a cylinder

    Hi guy's had a good ride up to peebles with a couple of mates and all great till i stopped to fill up, when i restarted her she fired up on 2 cylinders when i rev her she goes on to 3 as long as i keep the revs up everything is good but when i let her idle then increase the revs she splutters on 2 then picks up on to 3 cylinders, am i right in thinking either plugs or coil sticks, cheers. Yes it's a Tre-k 1130.

    Sounds like the typical coil stick issue but could be a plug on its way out

    Is it worth doing all 3 coil sticks and can you get to them by just lifting the tank but not removing it, cheers

    Presumably the same as the tornado. Mine had one stick fail about 5 years ago. No others before or since so would suggest no need to change all three.

    This is the way coil sticks fail. If you persist, the stick will break down fully and the engine will be permanently down to two.
    I've had two fail in the 13 yrs i've had Nell (maybe three) and that's the way they go.
    Replace the one that's failing and get yourself a spare.

    Thats sounds good to me, can you get to them without taking the tank off, just lifting it, cheers.

    For all thats involved in removing the tank Ron, I'd whip it off which will make working on the coil stick that much easier.

    The fuel line is 6 mm ID and that's an 8 mm coupler. It will fit if you expand the hose with an 8 mm ball end hex key.
    There are 6mm couplers available now that will make the job a lot easier. You can even get metal ones, but they are exxy.
    Some have fitted cheap couplers sourced from ebay but they have leaked, so beware.
