my 83 yz80k will start. three weeks ago it was running fine when suddenly it just quit. now when i try to start it it just randomly backfires. i will run you through the things i have checked/fixed. it has a spark, the carb is clean, it has compression, it is getting fuel, it is getting air. now the things that i doubt are wrong with it but have a chance. the muffler might have oil build up, the carb bowl might be slightly dirty but i doubt that since it was running just fine before, a carb jet might be clogged but i did take an air compressor to it so i doubt that. the thing that is confusing me is the fact that when i try to start it the engine just turns over and over then the bike randomly backfires. i doint know what would cause this to happen so i hope someone on here can help me thanks.
my dirt bike will not start. can you pls help?
