Hello everyone,

just got my pretty much bike in a box 96 cbr 600f3 most of the way back together and i cannot get it to start. it will turn over, but will not fire. I have checked fuses, sensors everything that has been suggested to me. even a new fresh battery! it will not start with fuel dumped into the carbs just the ocassional tiny back fire. i do not believe there is spark.

Any suggestions are welcome!

 

Remove the sparkplug, hook it back up to the wire, hold and push the start button. That will tell you if it's getting spark. Don't do that by the way.
But instead of holding it, with the plug connected to the wire, lay the plug threads against the frame. Then, while you are NOT touching it, hit the start button. You should see the plug firing if you look close enough.

 

No spark on #4

 

swap that plug out for a known good one. That will tell you if it's the plug or not.
Regardless, one bad plug won't keep the bike from firing up.
My bet is the carbs are wonky.
Instead of putting fuel in the carbs, try squirting a little into each plug hole then replacing the plugs. See what you get with that.

 

What should I do to the carbs, just tested plug 1 and there is a decent spark, I check th fuel pump and it works. I got a set of new plugs today still won't fire
