My front pipe is cool after running for a few seconds and the back one is really hot. It is running like crap and only if I keep the choke half open. The spark plug is firing up front. Here are my questions:

Do I have one or two carbs? It looks like 2.

I only see one fuel line off of the spit-cock to the carb in the back, does that feed them both?

Is there a fuel filter for each carb (If I have 2)?

Any ideas on what might be wrong?

Thank your for any help out there.

Yes you have 2 carbs the fuel line comming from your off/on fuel cock should have a filter in the line before it goes to a T fitting & splits off to each carb. The carbs could need cleaned, You will be better off doing a search on adjusting the carbs you have fuel / air mixture screws that is adjustable the idle is just one knob that changes both carbs at the same time. Then their is the carb sync adjustment. In order to sync the carbs you need a carb sync tool. It gets the carbs matched up you can do a internet search on how to make a sync tool & on the steps to sync the carbs. I would read about it first to make sure it's something you could do. Syncing the carbs would be the last thing on a check list. You have to remove some of the plastics to be able to get to the carbs where you can see everything but check all the fuel lines , check the clamps that hold the carbs in the intake boots, air/fuel mixture screws I think it's around 2 full turns out from fully closed if you close these off to check them you just turn them till they stop you don't tighten them down or you will damage them. After this stuff is checked if it all seems to be good I would clean the carbs & reinstall them & check if their in sync. I hope this helps.

they are a pain to take off ...lol.. i have dont this on several of the kawasaki V twin's ... its usually a dirty /clogged carb... get a can of chemtool carb cleaner and take them off and clean them out ... i would also change the filter while you are doing this ... i have found some filters start comming apart on the inside and let stuff get into the carbs and clog them on the V's i have 1 and most of my friends do also .. im the mechanic for our riding group and i get to do most of the work on all 9 of the V's in our riding group ... we also have several parts V's ...

ethanol in the gas is causing a lot of carb failure. sta-bil makes a gas treatment & ethanol shield. sta-bil is easy to find at stores. Once you get it fixed you may want to run one of these products.

      1989 Moto 4 YFM350ERW intermittent spark.
      Quad has set for about 7 years and was running when parked.  When I replaced the battery and attempted to start it had no spark. 
       
      What I have done.  Followed troubleshooting in the manual. 
      1.       Coil failed the resistance check so I replaced it.  Still no spark.
      2.       I performed resistance checks on the stator and they all pass.
      3.       Found a bad rear brake stop switch and unplugged it and connected the wires in order to disable.  Now I have intermittent spark.  I believe that the issue is with either the stator or CDI and not sure which.
      1989 seems to be a transition year for electrical.  I can get new aftermarket CDI units for 87-88 and 90-94.  I cannot get ones for a 89.  I can get new stators for 87-89 and 90-95.  Looking at the schematics the wiring on my moto is closer to the 90 ones on the ATV side of the CDI and closer to the 87-88 on the stator side of the CDI.  Looking at part supply sources the stator housing is the same part # for all the years and looking at some of the stators on Amazon that have the dimensions on them both of the stators are the same size.
      What I am thinking of doing is to replace the stator and CDI with a 90-95 one as these parts are all readily available.   Does anyone know if this has been tried before and if there are any issues with doing this.  
       As a side note I also have a 1993 Moto 4 YFM350ER that has been sitting longer but it is located about 400 miles from me at this time.  By doing this change in addition to being able to get parts I will also have 2 ATV’s that are the same electrically.

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

      Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!
