      check all the lines are on your fuel tank

      including the small vacuum line coming from your carb

        yeah, highly impossible to switch the leads around especially with where the plug are situated. one under the fuel tank and the other at the front.

            Any chance one of the plugs haven't been re-inserted properly?

                plugs are installed correctly, tightened firmly and leads securely on

                    yeah a little, the noise from around the carby area does sound kinda airy. if that makes any sense. its just so strange cause i didnt do anything except what i mentioned above and that shouldnt have created any problems.

                            It quite a common problem for the side stand switch to short out.

                            As to why most people disconnect them.

                              one of the little tubes coming from your carby is a vacuum line which should suck when you turn the engine over.

                              You need to connect this to your fuel petcock as the vacuum open the fuel line and allows the fuel to flow fast.

                              If you don't have this line connected you might be able to idle it but not much more than that.

                              Look on the bottom of your tank on the fuel tap more closely there should be a small tube where the line can attach.
