Why wont my yamaha aerox tick over - 2007 Yamaha Aerox R

Clean the carburetor. Pay special attention to the jets inside the float bowl area. Remove the throttle and air screws and spray cleaner into the holes and every other hole in the body of the carb. Remount the carb then screw the throttle and air screws inward until they LIGHTLY seat. Now open each of them one and one half turns. If the bike still wants to speed up the idle on its' own, the seals and rubber fittings between the carb and the cylinder are not sealing out the outside air. New seals etc., are needed.

You need to check if you have spark and fuel:
1: Remove spark plug and fit it back in the plug cap, crank over to check spark

2:If you have spark check to see if plug is wet or dry
(a)If dry, there is a fuel issue and you need to check by the carburettor and tank for fuel and/or any vacuum hoses not connected.
(b)If wet you might have a faulty plug or flooded in which case try starting with full throttle and no choke(if Manual choke)

3:If no spark, look for the cutout switch(normally on the right hand side handle bar) to make sure it is on and that there is no water residue on any HT leads etc.
