So my bike has been sittin for a month or so I changed the thermostat and went to start it after I gave it a jump. It's started to crank so I adjusted my choke for cold start tried it a couple more times. Then after like the fifth or sixth time. When I hit the ignition button then nothing. Help needed thank you

 

first place i would look is fuel and air lines. vacuum hose came off, or tank vent issue. if all that checks out, check the service manual on how to check spark. pray for the easy fix first.
