If there is that much coming out, it's like DD said..there is too much getting into the combustion chamber. Have you changed your air filter recently? Just curious...make sure it's not clogged.

What dd said.also check your dipstick for overfill. And check spark plug. If excessivly oily. Might be time for a valve and/or ring job. How many miles on your unit?

All factors

good luck and good riding

just took one apart doing same thing looks like it need piston rings and a valve job take off the head and look at the valves for soft oil carbon on intake valve and see how slopy the piston is in the cylinder

first thought,

1.check not over filled with oil.vacuum line could be sucking oil. if dirty drain and replace quick solution could go thicker eg 20w-50 bike oil

2. check filter

3. spark plug what color?

4. compression if on the low side ~120psi its rings or valve. if high could be sticky or broken oil ring( if they are sticky, try SEAFOAM, and or intake cleaner, warm upto temp and add little and rev a little and then add more until it stalls. let sit for 30min and run it until warm and exhaust should stop smoking.

5. take head off check valve guilds.

6. check rings and bore size and roundness

      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

      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.

      I recently bought a 87 TRX 250 not running of course, the owner had a brand new Key Switch on it.
      I think it is the wrong one or wrong wire colors as the colors dont match up with wiring diagram i downloaded for it. 
      anyone have a pic of their ign switch wires where they connect with the wire colors for that model? I ended up leaving the black/w stripe and
      green wire disconnected in order to hot wire it for other testing but would like to know as the colors dont match diagram.

      Im aware that this relay needs a positive (+) and a negative (-) to activate the other side. The blue wire is the neutral wire so when in neutral it gets ground. The green wire is from the parking break; when you pull the break in it gets ground (-). however one of those two needs to be neutral so that the positive from kill switch can go to the starter relay. The ground from the starter relay is from the start switch. Which one (neutral or parking break) should have a positive (+) voltage?
