    @irongamer727 Just need to get yourself a kickstart now and it'll be like a real crosser.

      @calum I've thought about it. Could get an old dtr engine for £90 with kickstart.

        @irongamer727 Yeah, that's about the going rate for everything you need, plus you'd have a spare engine lol.

          What do you think? The DT is refusing to start cold. Always have to bumpstart it. Choke or not. Once warm everything is more than good.

            @irongamer727 You running the stoke carb?

            I always had issues with the stock carb.

            What plug you running.

                @irongamer727 Before you mess with the settings, try stifling the airbox, restrict the air box, see if that makes it better or worse. Or take the snorkel out. That'll give you a hint as to what the problem is.

                  @calum the entire snorkel and the top plastic is cut out. I'll comment on the post I did a while back and you'll see

                    Ah yeah, so with that then, it probably just wants a tad more fuel to compensate.

                        @irongamer727 Either way it doesn't sound right.

                        If it were fueling, it would start if you opened the throttle ajar.

                          @calum recommendations then?
                          It has never ever wanted to start with throttle. With or without the big bore. With the previous cylinder it would at least start fast cold.

                            @irongamer727 Better carb mate.

                            I had issues with my Athena as well. Carb sorted that out.

                                          Things are not going my way. 180km into break in I spotted 2 small holes on the cylinder. I have spoken to the company I bought the kit from and they will contact Athena for assistance. Hopefully this ends well..
