  • Imgur Image Hosting Blocked in UK...

    @HOTSHOT-III Hopefully the issue gets resolved as I don't want to lose the data they're hosting.

    The important stuff I ought to host here to guarantee it isn't lost.

  • Imgur Image Hosting Blocked in UK...
    CalumC Calum

    See the recent news that imaging hosting site Imgur has been revoked access from within the UK.

    This is incredibly frustrating as my builds and tutorials are now blocked access there.

    To access any material on Imgur which this forum relies on, in an attempt to migrate, a Virtual Private Network (VPN) can be utilised to circumvent this measure until the restrictions are lifted.

    There are free alternatives that can be used, but Opera offers a Free VPN service built into the browser, and I have confirmed today that this works.

    An alternative approach is to use another site like Flickr or GooglePhotos. I migrated to GooglePhotos a while back, but found it painful to use.

    Trust me, I love my RS, but the DT is just a solid whip.

    I now have an RS powered trail bike. Never ridden it, despite having it 4 years.

    Only use Athena, Genuine or Vertex head gaskets. The white ones blow straight away.

    My advice would be to keep your DT.

    I utterly adore my RS, it's absolutely rapid.

    But the DT, especially yours, is the better bike to have and enjoy. It's utterly bullet proof, which makes it all the worthwhile.

    The RS is wonderful, just tempermental.

    Hi @gary76,

    What condition is it in?

    Is it full power or restricted.

    Let's say an original, restricted model, mint condition £2500.

    An original full power one £3000.

    For reference, this is mine.

    Yeah it's a nightmare trying to get the torque wrench in, can help to drop the front engine mount bolt gives you a bit of wiggle room.

    Just go over the bolts and make sure none of them have rattled loose again.

    Often these things come from a very simple place. So just double/triple check all coolant hoses/unions etc.

    Did you torque the head up in a star pattern evenly?

    Did you retorque after a few heat cycles?

    You're running standard barrel yes, as the Athena kits need o rings for the spark plugs.

    @mbmO8 Just checking, you used a genuine/Athena/Vertex head gasket? Not a knock off. And the head gasket was installed the right way up?

    I've don't think I've seen it being done. It almost sounds by which point you'd have a KTM LC2, so why not just go and buy one of those instead?

    There are lots motorbike combinations from the Yamaha family which can be made to fit the DTR, so if it's upgrades you're looking for then it's worth exploring those first.

    Full rebuild sounds overkill for such a low mileage.

    It'll probably be something simple like gunk in the exhaust and/or intake or carb issue.

    I'd get a compression tester and measure the compression the engine's outputting. Should be in the 140 range if the engine is healthy.

    @HOTSHOT-III Absolutely spot on information here.

    I've not had the thermostat fail on me, but MY GAWD does my DTR run hot. I am not making this up, my Vespa runs cooler than my DTR.

    The DTR could seriously benefit from a lower opening thermostat, especially when you tune.

    I've removed my thermostat and now the DT runs a cool 60 degrees. But you're absolutely spot on about having pressure at the cylinder head. It is stops pockets of stale gas forming causing hot spots on the cylinder head (promoting knock).

    @YYHpilo Oh that is so fricken cool!

    So two strokes make an awful lot of power just in the head alone.

    I'd say the money is expensive and the best way to get performance out of your cylinder is to have the head ported to your setup (piston etc).

    But I'd buy this if I were still tuning DTRs. That's a lovely bit of kit!

    Your DT has a total of 2100 miles. Sounds PHRESH!

    Probably just do the age related things. Gearbox oil, coolant, air filter and spark plug.

    Anything else is just like, if it's in good condition then leave it alone would be my advice.

    You can find that sometimes crud gets into the inlet air ways or accumulates in the exhaust and this can adversely affect performance.

    Couldn't resist in adding a few carbon fibre touches here and there....

    I found a very nice Tomas Compitsite flywheel cover and fan shroude combo. As well as a gear selector cover and a spare wheel cover.

    Sadly, the other two items have not arrived yet.
