Ok well first of all someone told me that the problem with my bike was the spark plugs. but it still starts but dies all the time. so would the problem even be the spark plugs? well i just went down to canadian tire and picked up a new one. my friend helped me get the old one out and has know left me to put in the new one. The guy a bought it off thinks its not the spark plugs and says not to even touch any of that nemore and let him try to fix it. but i mite just try it out. My friend metioned something to do with a spring and shit. so what percautions and steps should i take to install the spark plug correctly?
