    Hi,
    I followed the advice of Spookdog and Stevie Wonder and ordered one in Portugal from Romeu..
    is now on its way and can arrive at any moment
    in terms of price this was also the best option.
    I'm very curious about the sound and performance.

    The engine stops when the connection is made, ignition is earthed. I don’t understand what your problem is?
    If you disconnect the kill switch the bike will still run…
    If you disconnect the ignition key block connector the bike will run but have no lights…
    Just fit the button and try it…

    Well I run RS 125 rear calipers on my stock DTRE master cylinder and the brakes are ace.

    On the front I swapped out the mastercylinder with something more appropriate, for said reasons....

    They are fuel overflow hoses. Attach a hose like shown on the other side and feed it underneath the bike away from any hot areas.

    They're designed to flow gas away from the bike and hot areas should the bike fall over and the tap not be shut off.

    @GiannisT The smart thing to do would be to tear it down and inspect/renew where appropriate. There is no shortcuts, one way or the other that engine is coming apart. If the swarf hasn't contaminated the main bearings it'll no doubt have damaged the big end bearing. Anything short cut you do will likely cause further harm and stress to other components causing bigger, more expensive, problems in the long run. That bike didn't die on tickover, going by the extent of the damage to that piston/head.

    The head needs throwing in the bin, it's trashed. You might be able to get a tuner to alter the squishband and remove the detonation/debris marks from the head, but as it stands it's a glorified paper weight.

    The problem with running damaged heads such as that, is that it encourages detonation, even if the jetting appears to be correct. In other words, it's just a shortcut to a blown engine, doubly frustrating when it's freshly built.

    My advice, don't scrimp on critical components, it'll just come back to bite you.

    You could spit the cases and inspect the components for wear. If all is in order then you may not need to renew (although I would anyway).

    You could just inspect it in situ and see if the float is okay and if the big end bearing is damaged by checking for play. No way to tell about the mains or crankcase seals without tearing it apart. If debris has contaminated the seals then it will never idle/run right.

    So the converter is only converting to match the KPH face then and not a real converter i.e. really changing to mph. Sounds like I need to find a proper MPH speedo after all! Don't suppose you have a good one you fancy selling? Appreciate your help as you have saved me a lot of aggro. Cheers

    @old-boy-racer

    Don’t forget that the oil pump is calibrated to the carb. It’s the right amount of oil for the air-petrol mix going in. If you put a much bigger carb on I would start thinking about the oil pump…
    Do you get what I’m saying? The pump is running at 50:1 why would premixing at 50:1 be any different? Think about it 🙂 …

    PS what carb does the Dtr 200 run? Cause the pump is calibrated to the carb, not the cylinder…

    @Hybrid_Theory01 It won't be the gearing, it'll be the starter. It's the same as if you bump start your motorbike in reverse then it'll go in reverse.

    So the kick starter mechanism probably isn't correct.

    Although, I cannot visualise how this can be the case. I can't see how the gearbox can be assembled in such a way, so the only thing I can think of is the engine going around the wrong direction.

    @SpookDog
    Now there’s some miles on it We’ve been opening it up a bit. Still running Kmh clocks and I kinda know they will be out but with me pushing 14 stone that’s close to 90kg in new money with jacket helmet boots n gloves it’s revving out in 5th and pushing 9.5k in top well into the 120-130kmh. So I’m well happy. One thing I am really pleased about is it’s still pulling past the power through the gears and it didn’t drop past 8k with a bit of an incline. I’m sure if I was 17 again weighing in at 10 stone wet it would be well into the red.

    @perky Yes, that's what someone said the other day.

    The DTX Runs a Brembo Caliper too, which won't fit DTX forks.
