i am an mot tester,you must have a continuos sounding horn,get one from push bike shop with its own battery.you will need a speedo just make it look like it works as it is not tested.chain gaurd not needed for mot,if you have no lights make sure you dont have a switch.reflector the book says you need one,so while you are at push bike shop get a simple bolt on one.tank must not leak petrol,any breathers are ok but make sure not spraying on back tyre easy to put to drive chain.richard
