My suggestion - begin with engine cranking check. You can remove the spark plug and use the kick starter to see if the piston is moving. At the same time you can check the spark as well (attach the spark plug to the cable and keep the sparkplug in contact with the engine body while cranking the engine).Check the oil. Next thing is the fuel. Old fuel can cause start problems. You can drain the old petrol and put some fresh fuel.That's in case the bike has not been used last few months. Air filter cleaning and oil change are good thing to do as well, bu they should not be preventing engine start. Link to comment Share on other sites More sharing options...
