My 2003 yz450 has been the best bike ive ever owned. I pull it out of the shed sitting for a month and three kicks shes good to go. If its warm it starts first kick nd i mean every time. cold or hot it starts great.. UNTIL.. last time i went out i got it out of shed started it rode it in the street and stopped and went again no biggie. I ramped it on the pickup and strapped it down like I always do, get the bike out to the track and thing wont start for crap. I tried a huge hill and popped th clutch made a bogging sound. I eventually got a quad.. to tow it on the raod and roll start it took a while. It has done this once before and then this time in the year ive had it. Anyone got any ideas?? is it just flooding out from the drive. any help is appreciated races start next week and dont wanna be that guy.
