my yamaha aerox wont start it started fine but never started it one day now it wont start when kick starting the lights flicker on and sometimes it ticks over for about 3 seconds and cuts out i have got a new battery and spark plug but still not running.

check the spark plug for water/coolant the most common reason the do this is the head gasket degrading,its just a rubber o ring and if its flat or damaged it will leak and foul the spark plug stopping it from sparking,i have changed loads of them also buy a genuine gasket or you will be back here again .
