  1. What level are you filling it to?  Should be at the top of the matrix plus a wee bit.  If you fill it "full" then it will burp out to reach correct level.  Hot coolant expands.

    Be good when all entries are online so our data is safer...   I hate to think what happens to some old paper entry forms !  

    I've never heard of anyone hacking in to a website or e-mail account and stealing data that was on paper.  In my opinion it is more secure - someone has to know where it is then break in to the premises to get it.

    Hi All, I realise this is an old thread but I’ve had 4rt starting problems recently and wanted to share the little trick I’d been given by the mechanic at Sandifords, Burnley.

    In short, I brought my 2015 4rt home on my trailer through some miserable wet and cold conditions, I spent a week pulling my hair out trying to get it started, checking electrical connections etc without any luck, in the end I phoned Sandifords and they told me to do the following -

    Open the Idle screw under the seat by another 2 full turns (factory setting for the tickover is around 3 full turns out).

    Fully open the throttle and slowly kick the starter to reset the ECU (the bike won’t start at this stage).

    Return the throttle to closed and kick start the bike as normal (no throttle).

    The bike should start with a high tickover.

    Turn the tickover screw back in until the tickover is ‘normal’.

    Hopefully that will save someone the hassle I had..

    That seems a bit more complex than the standard two kicks at full throttle with the kill button depressed that I have to do frequently.  Had you tried that method?  Once you get the tickover set correctly you don't want to be fiddling with it unless absolutely necessary.

  4. I used to find it was the head of the bolt that was making contact with the joining link as it would loosen off slightly, I just kept the bolt tight.  Clearance is tight so putting the spring clip to the inside of the chain also helps, but it's good practice anyway.

  5. I think there are some formal parameters to define such a bike but can't recall where I saw them. I do, however, remember that when indicators became a requirement in the UK "trail bikes" (they were the ones people were worried about) were excused this and also the mirror requirement if my memory is correct.  Probably covered in Construction and Use Regs, which incidentally render illegal almost every new road bike with a plastic stick, instead of a mudguard, to carry the rear numberplate.

    No. Idle jets are an M5 thread, main jets are M6.

    P.S. A rich mixture does not cause 4-stroking, but it can exacerbate it.

    I'd be intrigued to know what you think does cause fourstroking, if not a rich mixture.

  7. 300 degrees from what?  How many turns out is it.

    I'm guessing, at that age, it may have been lying a while in which case the carb may need a better clean than you have given it in order to get gunge out the passages.

    We didn't have a world championship until about 75 ,every sport seems to need a world championship there days from tiddlywinks to Yachting and beyond,it's nonsense.

    I've some sympathy with that view Breagh but, because I am an enthusiast, do feel that trials should have a world championship, but perhaps not what we've actually got.

    You are old enough to remember the estimable Ralph Venables and to have read his weekly thoughts; I suppose we youths regarded him as an old reactionary (much as some will see us now) but as I recall he predicted that trials would become the flea circus it has.

  9. You may as well clean and grease the swingarm bearings while you're at it. However, you may well find that the lack of play there is due to a build up of crud and the bearings are siezed/rusted and need replacement.

    Thank for that!! So just normal unleaded then? As I was told it should be old leaded Petrol but I can't get it anywhere.

    Thanks

    No wonder, lead in petrol was banned nearly twenty years ago.  It was better stuff though (for vehicles anyway) - someone dragged a Scorpa out the shed recently and it fired up second kick on what had been lying in the tank.

  11. Surely an enthusiastic importer should not have to be bodging up the exhaust on a machine produced in 2018 by one of the world's biggest manufacturing nations?

    While that test was not carried out to the FIM standard it doesn't lead me to think that the bike would pass such a test, which involves full throttle.
