I'm looking at a 2001 325 Trail Boss, auto for my wife. Nice looking, well taken care of, adult driven. He wants $2100 which sounds like an ok deal. My question is about this unit having carb troubles in regards to changing elevation. I've been trying to find out as much as I can about this bike, and I've read a couple of times that when changing from low elevation, such as the dunes at the Oregon coast, to higher elevations such as where we live at 3200 ft, that it doesn't want to run well. Is this just an isolated problem, or a standard problem for this bike ? Also, is there a fix for this problem?[img]i/expressions/face-icon-small-confused.gif[/img]

I have one but don't do elevation changes

 

It's not an isolated thing. All carbs would need to be jetted for the proper elevation.

Having said that, the carb on the boss is a real pain to get to. You'll have to take off the side panels, the tank cover and move the tank to get to it. Not difficult, just a pain.

 

We only go to the coast about once a year. (We live in sw Idaho), so most of our sand riding would be at St. Anthony which is 5K in elevation. Ours is 3200, so maybe we will find jetting that will possbly work passable on the coast and also at home. My 1996 Polaris 425 Magnum 4x4 doesn't seem to have problems when we take a trip to the coast, so hopefully we will luck out with the Trail Boss. Not much of a wrench, so I don't look forward to having to change jets [img]i/expressions/face-icon-small-frown.gif[/img]

I have a to do list when I get home, but I'll try to look in my manual and see what the factory jets are recommended for low and high altitude.

My biggest complaint on the jets is that the numbers stamped on them are too small to read for an older guy that needs glasses. [img]i/expressions/face-icon-small-blush.gif[/img]

Oh, and welcome to the forums Krazybob. [img]i/expressions/face-icon-small-smile.gif[/img]

 

Thanks for the welcome [img]i/expressions/beer.gif[/img] [img]i/expressions/face-icon-small-smile.gif[/img] As for being old, well I can relate to that, since I'm 69 yeras young [img]i/expressions/face-icon-small-happy.gif[/img]
But I refuse to grow up, so here I am still riding dunes and having fun [img]i/expressions/face-icon-small-wink.gif[/img]
Appreciate to hear what your manual has to say.

My wifes machine is that identical one. We live in Denver, CO and it still has the stock jets in it. A friend of mine used it when I took him for a ride to the mountains and we ran up to 12,000 ft and other than a significant power loss, which I also experienced on my 400 cc 2 stroke, it still ran just fine. I could tell when I took it for a spin that it could really use a leaner jet but it never fouled the plug to were it wouldn't run all day and we put 30 miles on them that day. The Polaris machines come jetted from 0-6,000 ft so you shouldn't have too many problems unless you are looking to run up >6,000 ft all the time.
