I have an 1993 CBR 600F2 that will not start and am dying to get help with it because I dont want to tear it up trying to figure it out. History... Purchased it 5 years ago this summer from the original owner with low-milage (8,000) and it ran beautifully for the first 3 seasons. Ill save you the details but it sat for about the last 18 months. It has almost 12,000 miles on it now. I put sta-bil in it when I put it up last. At the end of last season I got it out and even though I had been trickle charging the battery it was shot even after charging again. So it stayed in the garage. With spring coming this year and ready to go I bought and charged a new battery, drained the fuel tank and lines, replaced the fuel filter, cleaned and oiled the K&N filter...and tried to fire it up and nothing. Well nothing as in it turns over and over and over and it did backfire pretty big a couple of times and has made a sound like it is sucking in through the pipe like something out of a science fiction movie a time or two but still nothing. I opened the two outer float bowls to be sure I had fuel running through and it does. Can you help??? I cant spend a lot but I can do the work.
