      @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 don’t use the bike you will easily destroy something my 250 is about 80nm I just stuck a ratchet on there and cranked it don’t (don’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?

                                  @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.

                                  @calum i am starting to suspect the balancing shaft more and more... how do i go on to check it, and time it properly?

                                    @bananper Whip the clutch cover off, whip the clutch basket off.

                                    Rotate the crank shafter around. The two dots on the primary shaft cog and the balancer shaft cog should meet. If they don't then the timing is out.

                                    It does destroy bearings, but you should get away with just sorting it.

                                    If it's not that, then it's either a rough engine, clutch imbalance or lose/worn engine mounts.

                                          Cool that looks good then. Now you just need to make sure the clutch is balanced properly.

                                          No you don't need to split the cases. You just set the piston to TDC.
