I am having trouble starting it and am going through spark plugs about one every other day, when i change the spark plug the top is covered in carbon. i know spark plugs should last longer than this, what do i need to fix?

you can clean the air filter with water but dont twist it or it will rip so just squeeze it beween ur palms and start the bike to see if it changes any

if its dry black deposits its running too rich so this means the fuel/air mixture has too much fuel in it so check the air filter is clean and not blocked up,if its wet oily black deposits then i expcet the rings have seen better days on the piston if its a 4 stroke engine that is?
