I have a CBR600 f3 that starts first turnover everytime. The other day it started and then shut off 2 minutes later. Now it wont start or pop start. I have checked the gas, the fuel line, the fuel pump, the spark, cleaned the carburator, checked the cam chain and still nothing. It turns over stong but will bot start at all. I did notice the carbs are not sucking in air when i turn it over. ? What else could it be? maybe you could help me because im getting really frustrated. I checked the coils as well

 

also iv checked the olms on the spark wire and plugs, along with checking the wires to and from

 

I was in your shoes last week so i know the feeling, hopefully i can help. You said you checked for spark, did you put a good plug on each wire and watch it spark? With your tank, airbox and whatnot off, looking down at the carbs, spray some starting fluid or fuel in each carb directly and try to fire it up. Lets start with those.

If you checked everything it should be fine. Are you sure the fuel is actually going out of the pump? Also if you spark plugs are old just change them. Look at the old ones. If they are too wet try cranking the starter before putting new plugs. You will see fuel coming out but its fine. It will dry out. Mine had the same issues when I bought it.

 

I was just headed to work 30 mind ago and my bike died it just sputtered and as I pulled over and stopped it died checked the tank and the fuel is low but it's not exactly empty could it be a fuel pump? Is there even a fuel pump on these as it is carburated? It's sitting on by the side of the highway I'm so worried hopefully I can get it home.
