    Mine sounded like that when the piston was slapping. I don’t think that’s the case with yours, as yours still clicks as it dies. If your noise came on suddenly then it might be kick start related. Try moving the kickstart down a bit while the engine is running. Be careful though, please!! See if it alters the sound...
    I can’t remember the ins and outs of the mechanism how the kickstart engages at the mo. I’ll look into it...

      Yeah, from what I can hear (I think!) it sounds like the noise an engine makes when you kick it over and hold the starter down. It’s hard to tell from a phone speaker...

        @SpookDog I really appreciate the time thank you, my one mate says he thinks it's something to do with waterpump but the impella still works and seems fine

          Definitely needs investigating that. Sounds like some gear rubbing on the housing.

            @Calum but the noise is literally only coming from the clutch side, my guess is it's either something to do with the waterpump or even the flywheel, I'll put the cover off tomorrow and check the flywheel, I know on my mates husky hes flywheel key broke and it made a similar noise but I'll definitely get back to you guys as soon as I know something, really appreciate the time guys thank you🙏😁

              Dude, check the throw-out cog on the kickstart shaft. It sounds like it’s not disengaging properly...

                @SpookDog I actually turned the Kickstarter while the bike was idling and normally it would make a noise but it didn't so I actually do think it might be that,I'll get a new gasket and pull the casing off to check the Kickstart shot man

                    @SpookDog will definitely keep you posted, yes I'm also sure it's that just gotta take a look at it the weekend, it shouldn't damage anything right? Just for 2 days I need to use the bike for work so it needs to wait till Saturday

                      I wouldn't ride it with that sound.

                      And LC engines have got to be hard to come by now surely.

                          Definitely sounds like something (a gear cog) is rubbing somewhere.

                          And there was nothing untoward about the engine? Nothing was lose inside? No metal filings in the oil?

                            Dude, if you can hold down the kickstart without it making the clacking noise while running it’s definitely it...

                              If you get stuck I have an old kickstart shaft assembly you could try swapping out. It absolutely has to bit it if it’s not making the proper noise when held down. It sounds like the cog isn’t going all the way back as it should...

                                @SpookDog It's not a DTR, looks like an LC.

                                  Sheet, my bad! I still think it’s the kickstart throw out gear. If you hold down the kickstart and it doesn’t make any difference to noise...
