    @Calum @declan @finnerz89 so here's a video on whats happening. Im not sure if you can hear it, but the whole bike is vibrating, espesially the chain and the rear half of the bike

        The thing is we can't really see how much it is vibrating, personally I don't think it is much of a problem. All of my 2-stroke off-road bikes have vibrated, most notably my GasGas. After 10 minutes of full throttle you won't be able to feel your feet. How many miles has that engine got? If your bike is vibrating more than you believe it needs to, it would make me think the problem is a bigger one. I'd check the engine mounts, however unlikely it is.

          @minia around 24k, the engine has been rebuilt by an mc shop when the previous owner had it. It has never been shaking like this, just came out of nowhere

            @bananper If that engines been split, then they either haven't timed the engine correctly, or the clutch hasn't been assembled properly.

            Either way easy job to fix, engine in the frame jobby.

                @bananper The clutch basket is fastened in with a nut and a tab washer.

                    @bananper Have to check the manual I'm afraid. I'd image it's pretty high and you will need to lock off the crankshaft to do it.

                      @calum i'll take the bike to my local mc shop and let them have a look on it, i think the bearing located behind the clutch bucket is bad

                        @Bananper A loose clutch basket seems like a good culprit, but you need to know why it is loose. Or what made it loose. Well anyway, if you're taking it to a local shop they should be able to find and fix the problem. Afterall, the DT engine is pretty easy to work with.

                          Is the basket supposed to sit really thight or should there be some movement? It's not very loose, just a tiny bit. Do i need to split the engine to change the bearing behind the basket?

                            @bananper any movement will be highly exaggerated when the engine is running donโ€™t use the bike you will easily destroy something my 250 is about 80nm I just stuck a ratchet on there and cranked it donโ€™t (donโ€™t do what I do)

                              Am I the only one who's noticed the chunk missing from the pressure plate? Lol

                              I'd like the know where the missing piece went

                                @finnerz89 That's some beady eyes you have on you.

                                Without that, the spring won't torque down properly.

                                I can't say what real world difference that will actually make, but it might be enough to cause a problem.

                                  Yup, i'm getting a new pressure plate obviously. I took the bucket of, and the axle is moving a little bit, it shouldn't move right?
