Here is the story: Me and my friend went riding yesterday and his bike fouled a plug, so no big deal he changed it and left it in his garage until this morning when we were gonna go riding again. well he started it up and let it warm up for a few mins and them cracked the throttle two times and then on the third it bogged down and died. then he tried to start it and kicked it four times and it didnt want to start so we checked the gas and the plug again and everything was good so he tried to kick it again but it wouldn't kick like if it was seized. after that he started freakin out checking if the gas was mixed, if there was gear oil, if the air filter was clean, and if there was fluid in the radiators; all was good so we have no clue what is going on with it does anyone have any suggestions anything would be helpful cause we have no clue ?????
