it ran beautifully when i rode to put it away in storage for winter, put a battery tender on it, a bike cover, and was carpeted underneath, week after christmas when it was like 60 outside, i wanted to get it out, it started but barley, idle was real low and no matter what i did i could not get it up, then it stalled and has not started since, even push started down a hill many times, pulled plugs, they were fouled, fast foreward to last night, put new NGK's in her, and tired again, this time with the choke off, still nothing, not even a hickup, coils looked good when it was apart, fuel filter was full, any suggestions? its a 2000 CBR 600 F4 with about 12,000 miles Thanks for any Help -Jack-
