yamaha 125 breeze spark and compression wont fire

[aftrmath99]

have a 1996 yamaha 125 breeze that wont fire  has plenty of spark  good compression  but wont actually fire. put gas directly into sparkplug hole and still wont fire im baffled  its not a weak spark if you put gas into the plughole and you have spark  it should at least fire  was running great  then the next day  nothing checked the on off swicth it seems fine any suggestions should it still fire when you pour gas into the lughole if you have good spark?

It's the valves. They are way out. My friend had the same problem with his sons Breeze. You have to either adjust the valves or have someone do it for you.
