    The bike wont start off electric or kick start after winter and im baffled!
    It sounds like its just not getting enough umph to start.

    I have changed the spark plug, battery and put in fresh fuel and topping up the oil.
    I have changed the starter motor and checked that the air filter is working okay.
    Ive tried warming the spark plug with a blow torch and hooking the scooter up to my car battery. The spark plug is getting petrol as it should.
    It sounds like the noise is coming from the cogs inside the engine case but i cannot see any worn teeth and the belt etc looks fine.........

    Do you have any ideas what it might be please?

    youve changed the plug but is it sparking?
    try cleaning out your carb
    and does the startermotor turn the engine over?
