I got a 400ex and It wants to start but won't it has a hicup and I've tried changing the Jets and it just does the same thing. The timing is correct. I've tried roll starting it and it starts for a few seconds and the just dies. Does anyone have a idea what the problem is?

How old is the gas. Plug color wet/dry. Tap on float bowl stuck float. Gas not going to carb clean filter, Check flow from tank valve by pulling hose. Clean air filter. Air screw 1 1/2 out then adjust fuel screw. My guess its not getting gas check that first. Just happened to me and took right off! Its almost always something simple! good luck!

Put some fuel in the air intake and crank it over. It it starts running you know it's a carb issue. take the spark plug up and check for spark. It may only spark every other time. Good luck!

      I just bought a rare beast!
      By kawasig
      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      Where you like to ride and what riding does for you?

      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.

      2000 Honda 400EX Backfires
      By Trent Finnessey
      I’ve got a 2000 400ex with a dg slip on muffler, it came with he stock muffler on it but the previous owner had the dg in a box so I put it on. I’ve been riding it for the past month and a half and every time I let off it backfires, and the other day the backfires got way louder, 2x louder! I’m concerned that I may hurt my motor? Why does is backfire??? Thanks

      '03 Honda Sporttrax 400EX Carb issue.
      By Dumass
      My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area. 
      Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.
