Why Can't a Motorcycle Start When It's Hot?

[DiRose]

There are many reasons why a motorcycle may fail to start when hot, as detailed below: Reasons for failure to start: Specific reasons include the starter motor rotating too slowly or slipping; faulty coolant temperature sensor; insufficient fuel pressure; faulty fuel injector; clogged air filter; whether the spark plug electrode gap is normal and if there is carbon buildup. Analysis of motorcycle ignition methods to determine the cause of failure to start: Motorcycle ignition methods include electric start and kick start. Electric start usually fires up the engine in one go. If it doesn't start after two or three attempts, avoid using the electric start further, as repeatedly using the electric start without success can drain the battery and damage it. Instead, use the kick start. In winter, when temperatures are lower, it may be harder to start the engine. In such cases, adjust the choke lever—normally it should be pressed all the way down. For cold starts in winter, pull the lever all the way up. After the engine starts, leave it in the middle position for about 15 seconds. Once the motorcycle has warmed up, return the choke lever to the normal position by pressing it all the way down.
