Hi,

I just bought my first 4wheeler. I have a couple questions.

1. What are the stock carb settings?

2. Are these things known to make a bunch of racket at low idle? The engine runs at low idle, but it sounds terrible with all sorts of rattleing and knocking. Once I open the thottle it smooths out and sounds fine. Could this be the transmission? If I set the idle any higher, it won't shift into drive without the gears grinding.

3. What is the override switch on the left handlebar for? I was told you need to use it when you shift into reverse, but it seems to shift into reverse the same whether I depress the switch or not.

Thanks for any help,

Jay

o now i did not know that engages 4x4 in reverse...when u put it in 4x4 is their a anything u have to do for it to engage or can u just press the button, i just picked up a project 94' polaris 400 and dont know anything about the 4x4 or how it works.. i replaced the indicator light bulb that goes inside the switch and it does not turn on. does the atv have to be running or in motion for the light to be on?

Thanks all. Maybe I'll post a Youtube video of the low rpm racket it makes.

Do that and post the video in this thread. The noise could be norma,l two strokes have a thrashy sounding idle by nature, if it is worse than normal, it could be an indication of worn crank main bearings, rod bearing or wrist-pin bearing.

      In search of my first ATV? What are good older 4x4 models?

      So I decided to pick up a small trailer if I could get one for the right price.  I found this one for a few hundred bucks on Craig’s list.  It is  a galvanized trailer which is exactly what I was looking for. The wood was shot and needed some minor repairs which I could care less about as long as the chassis was good. 
      I striped it down and put a new deck on. I had some vinyl realtree graphics that I had laying around so I added them to the fenders which I think worked out well. Very happy with this little guy.  
      I'm having the iron workers at my jobmake me up a few lightweight side rails that will have a 22 degree bend in them to accommodate the tires that slightly hang over the edge and will incorporate some tie down points as well.

      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!

      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.

      So I’ve got a 2000 Honda 400ex absolutely love it!! I’ve had it for about a month, I ride with bruteforce 750’s, outlander 850’s and 1000 sxs’s and I was thinking of getting a trx450r carb and a full hmf exhaust. And probably doing the air box mod too, how much power would this give my 400? Just a little different or a big difference? Cuz if it’s not much of a different I’ll just stick with my dg slip on..... thanks!
