2000 Suzuki King Quad vapor locking problems

Recommended Posts

I have a 2000 Suzuki LTF -300 King Quad. My problem is it will start up great, very fast. It will run fine until it gets hot and I turn it off.  If I let it sit for a bit it will not start until I hold the throttle wide open and crank on the starter for quite some timr, acting has if flooded.....but I checked the spark plug one time this happened, went to change thinking it was flooded but only found a dry Plug????  It starts like if flooded but plug was dry, it takes awhile to start, then to get going I have to really rev it to get it clear and going...Thanks any suggestions would be great, thanks everybody in advance...!!!

Have you checked to see if you have spark when this happens ? I know the plug would be wet etc but take a look for shits and giggles when the bike won’t start if spark is there. 

Secondly I would do a compression test before and after the engine is hot as well as take the temperature of the cylinder head. You can do this with an infrared point and shoot thermometer to see how how hot the engine is getting.

      Hello eeveryone,
      Just picked up an 86 Suzuki LT185 for my daughter, and she's complaining that it bounces so bad over bumps that it nearly throws her off the quad. I have the tire pressures some where around 3 psi. I really can't go any lower than that. I noticed that there isn't anything in the aftermarket world for shocks and springs for this quad. I am wondering what others are doing to soften up the ride. Also wondering if there's a way to fabricate a rear shock, since there isn't one.  I appreciate your feedback.
      Thanks!

      I recently purchased a 2000 polaris xplorer 400 4x4.  When I bought it the starter was bad, speedometer didn't work,  and it had been sitting for 5 years. I replaced the battery, and starter. Changed all fluids, and got it running correctly.  Then replaced the speedometer in an attempt to make sure the awd would be available when needed.  And took it out for a couple hour ride with a buddy.  
      It ran great that ride with no serious problems just a little carb issues which I was able to take care of on the trails.  Then a couple days later I decided to take it out for a ride by myself,  again ran great no issues other than a couple times it seemed to cough and then take off again.  That day when I was loading it I noticed coolant dripping onto the trailer and the overflow bottle was empty.  
      Got home and decided to drain the counter balancer, when I did that I got about 3 cups of coolant. Im guessing that it needs new seals and all for the water pump.
      My question is how difficult is it to do the water pump and should I attempt it or should I send it down the road to the polaris dealership to get it done?
