  1. Ok, I took it completely apart. that hole looked sealed. I blew in it and it is sealed. The only other place gas could come from would be the pass through tube just above it. I took out the pass through tube and looked at it under a magnifying lamp... There it was... A small crack in the o-ring. I put new o-rings on it and put it back in. That fixed it... it was leaking down onto that other opening that made it look like it was coming from there...
  2. Hi All, Hoping someone will be able to help. I have a 2006 Kawasaki Prairie 700 with twin Keihin Carbs CKVR D32. The Rear Carb is leaking out the side during cranking. it is not the float bowl overflow. It is on the opposite side of the carb from the diaphragm. I got this bike not running and someone had already messed with it. I took the carbs apart , cleaned and rebuilt. Everything went pretty easy. It looks like it could be missing a small tube between the carbs but I have all of them listed in the service manual installed. See the pic for where it is leaking from... Any help would be much appreciated.. Thanks.
  3. Wow, nobody can offer any advice? I would like to know since the front cylinder connecting rod has a little play in it on the crank, can just replace the connecting rod bearings on the front cylinder without splitting the crankcase? Everything else seems great with no play in the bottom end.
  4. So is there a Kawasaki Engine Guru on this forum? I would like to get some confirmation on how to proceed. The service manual is good, but experience and tips are best...
  5. Ok, I took off the Rear Head first and found a broken timing chain and the piston had hit the intake valves.. I don't know if you will be able to see from the photo of the valves. They are stuck open and binding. The top of the piston looks fine. I then removed the cylinder. They cylinder looks to be in great condition, but I do not think these are factory pistons.. I took off the front head and everything looks great. Took off the front cylinder and it looks great. Same non factory looking piston on the front. I then checked the connecting rod on the rear cylinder, it feels nice and tight with no play when pulling it straight up and down and moves smoothly like it should on the crank shaft. Then I checked the front connecting rod and there is a slight amount of play when moving it up and down.. I do not think that is a good sign.. Ok, this where I need advice and help.. When I was a kid I used to build V8 muscle car engines like it was nothing, but I have never done anything other than rings or valves in these type engines.. Everything in the bottom end has always been great. So I am guessing I need a valve job with new Valves, springs, Etc.. All timing Chains replaced. I will check the cam for tolerances as well as the other head parts to see if they need to be replaced. So here is my question Other than rod bearings should I be replacing anything else on the bottom end? Are these known for wearing out parts on the bottom end? Should I try going back to factory pistons after I check to see the size of these and if the cylinders were bored? If this was your engine what would you do? Thanks for any help...
  6. Getting it stripped down and I am a little worried. I see paint markings on the cylinders.. F and R designating front and rear cylinders.. That means someone has been in here before....
  7. Hi All, I finished up my Prairie 400 restore and this is my next project.. It is a 2006 Kawasaki Prairie KVF700D 4X4 Mean Green Special Edition. I got this for next to nothing , it is in really rough shape. The current owner stated that the engine is seized and he only rode it twice after putting on brand new tires. It has been sitting in the yard under a tarp for more than two years.. Here it is when I brought it home. Actually in those photos I had already removed the recoil starter cover and put a 19MM socket on the bolt with a breaker bar to gently see if the motor was seized. I got lucky it is not seized and moves like it should until you start to feel it bind. If I am lucky this could be a timing chain or dropped valve. I will start tearing it down..
  8. I started putting the Prairie back together. I lucked out.. Between the two Prairies , at least one had a good part if the other did not.. I installed the factory head lights and they worked but swapped them out for some bright led headlights. Now that everything works perfectly I can do some cosmetic things like sand and paint the rims...etc... I was very luck that no engine work was involved and it runs great... My next project needs and engine rebuild ... I will start posting.. That one I will need help with....
  9. Next I did the rear brakes or let me say... I took off the rear drum and the brakes looked like new. Then I realized The rear brake cable from the handlebars was broken somewhere inside and the pedal cable had broken at the pedal.. This must have happened early on and they only had front brakes.. I was able to use the pedal cable from the 1998 and bought a new cable for the front.. Got them installed and adjusted. Rear brakes work great...
  10. It's running great now!!! I took apart the carburetor and soaked the parts in break cleaner.. Blew everything out with air and reassembled it. I was surprised what good condition all of the gaskets and parts were in. I cleaned out the gas tank and put on a new fuel filter. I added Berryman B-12 Chemtool to my gas as well as Sta-Bil. It started after about 3 seconds and idled like new.. nice smooth power all the way up... I had changed the oil and filter and will change it again soon. I replaced the rear end gear oil, should I say cleaned out some sludge and filled it with gear oil. I looked at the front brakes and they were metal on metal. I got some new semi metallic brake pads and caliper rebuild kits as they were frozen.. The master cylinder is shot too. I bought this master cylinder https://www.amazon.com/gp/product/B01N1JWGJK/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 I had used one before and it worked great and you can't beat the price at $17. The only downfall is that the factory rubber boot cannot be used. Once the calipers and master cylinder were off I blew out the brake lines, put in some new brake fluid and blew it out.. I installed the master cylinder and filled it with brake fluid and let it come out the lines until it was clean. Once I got the calipers apart I was surprised what good condition all the seals were in.. I used the rebuild kits anyway. And for those that don't know this tip. The easiest way to get the piston out of the caliper is with compressed air and a blow gun. make sure the pressure is set low. put a piece of carboard in front of the piston and keep your fingers out of the way. you can hurt your self badly , that piston comes out fast and hard like guillotine if you have to much pressure. insert the blowgun into the hose fitting and gently release some air. It will come out very easily. Once I got everything reassembled with the new brake pads I bled the system with a brake bleeding tool. It went smoothly and the front brakes work perfectly.
  11. Sounds like you will have it fixed in no time...
  12. I use a combination of Spray Carburetor Cleaner and then also soak the parts in Brake Cleaner. Make sure to get the service manual for the carburetor before you take it apart and read through it. Let us know how it goes.
  13. If it has a choke use it for a few seconds and then open the choke and it should start. It does not take much for the carburetor bowl to fill and be ready. I would still open the carburetor first and rinse it out.. lots of times the debris falls out while cleaning. If you are careful and don't ruin the gaskets you can possibly get away without a rebuild kit. I would do that for peace of mind. If it even just runs a little better after cleaning it you know for sure it is a carburetor problem before you spend the money on a new caburetor..
  14. Normally you replace the filter if it has one. Or you put one in to protect the carburetor if it does not have one.. Factory parts are always best.. If you clean you carburetor very well and rebuild it , it should work like new. I myself have used aftermarket replacement carburetors that sell for around $50 on Ebay with no problems. Find a seller with positive reviews. I only use them if the factory carburetor is beyond repair or missing.
