Honda cr125 won't start

Answer 1

First check your spark plug. second, clean your carb out and check for any debris. third, air filter. My buddy had an old 1986 kx125 and it wouldn't start. we couldn't figure it out for like a month until we just took the air filter off and it started right up. But please don't run without an air filter, it could cause 100's of dollars worth of engine damage. and if none of that works then take it to your local Honda dealer and have them do a tune up on it.
