I am new the the crotch rocket scene and I just bought a 2002 CBR 600 f4i. This bike had sat for a while, but it was started regularly and when i bought it, it started with ease and sounded and ran great. When i get it home it's running and starting just as it should before i go to bed. I wake up and try to start it and nothing. So i thought maybe i flooded it, so i let it sit another day not messing with it and today it does the same thing. If this helps any, the guy i bought it from kept it in a warm garage, and i kept it under my car port on a cool night when it began to start having this problem. From all i can think of is that I either fouled out my plugs or it's something with the fuel injection. Please, if anyone has suggestions it would help greatly. I don't want to get into spending a ton on taking it to a shop if i can fix it myself. I'm just confused as to how it can go from running and starting easily one night and the next morning not start at all. Thanks for any suggestions!! I need em!
