XJ700X Spark plugs

the picture shows, from top to bottom, 2, 4 and 3. the last 2 look like they were not burning at all. My carbs were overflowing and I basically didn't find any gas in carbs 3 and 4. Was this bike trying to run with only 2 cylinders? What do you think?

 

No fuel means nothing but air to burn. Looks like you'll need to go to church:

+1 from Tony, you will have to take the time to go through those carbs. Not just a little bit but take them to "Church". Then comes the fun time of getting the valves in speck...the "X" is something else to work on with it comes to valves so just take your time and get it done right. Keep us posted on updates...

 

Oh, forgot about getting the valve clearances within spec. That should be your 1st priority before going through the carbs.
