      Put in the general section as this is not a dt it's an am6 engine 1st and 2nd are fine after that the revs die right down and literally idles along at about 5mph

        Is that the 50cc minarelli engine?

        Should be in the technical engine zone mind you.

        What's the compression like.

          @Calum sorry but yeah it is and it's got a new top end I'm replacing it with a dtr engine hopefully but I would love to know the issue compression is great reeds look good runs good other than an oil leak

            @Calum seems to go pretty good on a crate with the rear wheel in the air

                Yeah but there isn't any load on the engine so it's not a fair test.

                It could be a multitude of things, from bad ignition to bad fuel.

                If the compression is good then it could be losing power through either the transmission or clutch.

                  @Calum the clutch isn't great and you have to redline to start moving
