I think I may need to remove and clean the jets on my '99 Explorer. Can someone explain how to do this? How many are there? What do I look for? Where are they located? What do I do to the jets once I get them out? Is there any adjustments once they are back in place?

All help is appreciated.[img]i/expressions/face-icon-small-confused.gif[/img]

 

Just curious why you think you need to clean your carb jets. I assume that you have a 400 2 stroke xplorer. The main jet and pilot jet are both fixed jets with no adjustment. You can however change the size of them but be careful this can really help things or it can melt your motor. The only adjustment is the needle that seats in the main jet. You can adj this up or down as needed.

 

Pennyless, Thanks for the information. I think I may need to clean the jets because the bike doesn't perform like it did last year. After getting it out of storage this Spring, I noticed it did not have as much power running up the mountain trails. I ran the carb dry before storage, changed the plug this Spring, and still can't figure it out. Usually it runs great, seems much faster. I also tried adjusting the air valve. Maybe it needs more tweeking. Never have been in to the carb. That's why I asked those questions. Any suggestions?

 

If you still have the gas in the tank from last time you rode and no stabilizer, then dump the gas and get some fresh, then take your carb apart and clean the varnish that will accumulate. Here is a hint, from now on, before storage... put fuel stabilizer in a full tank of fresh gas, run the atv for a few minutes to let the fuel stabilizer distribute through the carb, shut it off and then you go back to it next time the gas will be good and the carb will not gum up. Running the carb dry, which can never be done without dissassembly, will allow the small amounts left in the carb to turn into gum and varnish which is extremely hard to clean out, but if you use the method I described above, I promise you will never have another gas/carb problem after storage. I have used this method on my jet-skis each year and after disassembling the carbs, they look like new. When I changed my factory carb out to a 38 TMX I took off the old carb and dumped all the gas out, disassembled it and all, but I didn't get it all out because after it set there over time it got alot of gum and varnish built up in it, that was the gas that I couldn't even see left in it. The reason you leave the gas tank full is becuase anytime you have extra space inside the tank and it is vented, which it is, moisture will accumulate over time in your tank and ruin your gas. Hope this helps. Here is a link to a parts explosion of your carb. Good luck and hope this helps. Carb
