Well I think that it's a gas problem. I was riding yesterday, and went on a 15 to 20 minute ride across the dunes. I stopped to take a breather and when i went to go again, i had no power. I couldn't even get up the next hill. It was really wierd. It's kinda like i'm flooding it when i give it gas. It will start and Idle, but I can't give it gas or it will die. I was able to get it to a nearby parking lot and then my dad rode back to the truck and came around to pick me up. I had to pull the choke after i got it going, then it would run just enough to get me out of there. Any suggestions would be greatly appreciated. Otherwise I will have to take it into the shop and pay those $#@@ a lot of money. On a side note I took the air filter off and it seemed to run a little better, but the air filter looks clean. It's a K&N. I'm thinking it might be a fuel filter but I don't even know if this has one of those on it.

 

If it's a fuel problem it either has a cloged fuel filter, vent line, needle and seat or main jet. My friend has a scrambler 400 and had simmilar problems and found it to be weak reeds, they will go bad out of the clear blue sky I don't know why. Hope you fix it

 

try cleaning your air filter.

 

Did u check the spark plug?

 

check where the throttle cable connects to the fuel and oil cables. I have a friend that had what sounds to be the same problem and the cable had came loose.

 

sounds like a piece of trash in the main jet. pull the bowl and clean everything and you should be fine. Pull the carb off to do it and it will be easy. It wont idle well if the reeds are bad or broke.Bubba

 

Thanks for the ideas. I have checked the Air Filter it's fine. It seems to Idle ok, it's just when i give it gas that it bogges out, almost as if it's getting flooded. I will have to wait until friday to pull the carb, however I have never done this before. Any special advise in doing this so that I don't screw anything up. Once I get it off will it be obvious if that is the problem? What do I use to clean it, just some carb cleaner? You guys are awesome, sorry if i ask to many questions.

 

Along with what the others said, change out your fuel filter (to prevent future problems). It's on the left hand side (viewed as you're sitting on the bike) next to the tank, by the frame. Your oil injection filter is there also. Change 'em out at least once a year, if not more.

Once you get the airbox off, you'll see the clamp on the intake boot. Loosen that, and the carb can be worked off. To get the bowl off, like Bubba was suggesting, remove the larger bolt on the bottom of the carb (this will drain the fuel out of the bowl....before you even start, make sure to turn your fuel valve to off.) then remove the phillips screws on the lip of the bowl, and it'll come right off. Your main jet will be right there in the open, a good time to remove it and make sure it's clean. Don't forget to check/change that sparkplug if you haven't recently. A little maintenance goes a long way. Ask all the questions you want, that's how we all learn. Happy riding[img]i/expressions/face-icon-small-smile.gif[/img]

Try looking at your clear vent lines. I had a similar problem, and one of the vent lines that they stick in a hole on the frame came loose, came in contact with the muffler, and melted shut. A simple snip with scizzors cured the problem

 

I agree with this, my Trail Blazer did the same thing, all I had to do was remove the bolt at the bottom of the carb (there was dirt settled at the bottom of the bowl. I cleaned it out, turned the fuel switch on to get any remaining dirt out of the carb and reinstalled the bolt. Ran like a champ after that.
