My bike was running fine when i went to meet up with my friends, i didnt let the bike warm up bc i was in a hurry. stopped at a gas station to fill up on gas and started ok again. when i met up with my friends the bike wouldnt start, which was strange, bc i charged the bike in the morning. i figured it was a battery problem so i got my friend to gimme a push and it worked. the next day i tried to start it but it wouldnt work so i fully charged it. When i tried starting it again after it was charged it started up easily. About a half day later i tried starting it again but it wouldnt start. I can hear the fuel pump and everythign but when i tried to turn the engine it just wont start. Yesterday after reading some threads, i charged the battery back to full, opened the throttle all the way, and started the bike, which worked. I let the bike sit til the fan turned off and parked it back in the garage. Today hoping that fixed the problem tried to turn it on but now i cant get it to start at all, even with the trottle method and fully charged battery. are the spark plugs fouled? and how did i do it.
