    So i got all my bits and have all been fitted. went for a 40 mile ride last night no leaks and no need to top up coolant,

    on the way to work today 30 mile trip let bike cool coolant is just under rad neck so possibly just working out air bubbles so probs lost 5-10ml

    this is using the copper gasket with copper sealant "spray a gasket" type of stuff

    see how it goes on the ride home 😞

      Update,

      went to go get a maccy d's for lunch lost a bit of coolant, so im afarid its still not done anyway got a second head now so ill go get that skimmed and the barrel checked, why are these such a bast**d to seal done x amount of 2 stroke head gaskets never had a leak., yet the dt is a pain. so im just going to go on the assumption that things are warped somewhere, at least i got a geunuine head gasket floating around now. the head gasket should show where the leak is hiding .

      i think its safe to say yamaha should have used O rings instead of steel gaskets like all there other 2 strokes, funny that iv never seen a AM6 or a rotax 122 (not yammys obv) head gasket leak there both oring'ed, i feel a experimental project comming on 🙂

      has anyone done it before ?

        @tomimsmith1992 Yes actually have seen it before. Although you still need to seal against the rest of the faces.

        I a, surprised you are having so much trouble. I had one head gasket go on a cheap head gasket. And if you have seen my belgarda build then you know I have dealt with rough engines lol

        You had the barrel skimmed as well?

          well im actually debating weather im just panicking,

          head and barrel skimmed and copper gasket with copper seal torqued to 22nm. the water has dropped in the rad to what i filled it up to, water is just sitting below the rad neck, and don't seem to be losing anything more, that's probably just where the water level is set.

          like i said im probably just being a idiot and lacking faith lol. i'll see how it goes for a week and keep an eye on it,

            @tomimsmith1992 You would expect it to drop a little once it's bled etc.

            See how you get on.

                @tomimsmith1992 You can expect the water level to drop over time, if it's always above the top of the core you should be fine. Mine usually settles about 5mm below the neck and is good for over 800 miles or more untouched.

                    Update, All is good ! looks like its fixed for now ! 🙂

                    can someone remind me noise from clutch in neutral but when you pull the lever the noise goes ?

                    can't remember what it is the cause ?

                      Clutch needs to be balanced properly if it's dismantled.

                      But But noise is generic. Is it metal on metal sound?
