I have the 2000 polaris xpedition 425 cc 5 speed. One time when I parked my atv in the woods. It was
leaning to one side by almost a 45 degree angle. Not tipped over of course. When I went to start it, it acted like it did not want to start. I did get it started, finally. Another time, I completely tipped it over on one side. I was only going about 1 mile per hour. No harm to machine or me. WHen I got it up right. It was hard to start again. Do other atv's act like that and what would
be the cause? Should I just choke it then?

My dad up north is going to drop off my atv to the polaris shop to get my black box, reverse actuator
replaced. This is the part that polaris will pay for the replacement because it was faulty in the first release of the machine. I even had trouble with it again on saturday. It has that lever on top and moving it forward by hand always gets me out of the jam when it acts up.

im not actually sure but i beleive its because the fuel somehow floods it,or the float is put in a full open because of the angle? i actually just rolled my exp. on its side,catching it with my leg before it rolled on its seat,a very slow roll coming out of a deep mudhole,on its side it was still running till i reached up and shut it off,but when we got it back to level ground on all 4`s it wouldnt start..drained the little bit of oil that came out of the crankcase breather which is attached to the air filter box,held the accelarator full open it started right up..tried a few times before we tried full throttle open trick but it wouldnt start..dont know if this helps but it worked for me,oh and i pulled the plug out of the overflo tube(carb.) that i have installed and it was full of gas

 

Every atv or motorcycle we ever had was hard to start if parked leaned over enough. I think it caused the engine to flood. The worst was my old Honda 250R dirt bike. If it flooded out, it was easier to push it up a hill & bump start it than to kick over. Ususally opening up the throttle at least part way (IN NEUTRAL) will help considerably.

Ranger,
Its the same reason that when transporting your bike down the highway you should shut the main fuel valve off.
With your bike on level surface, the float level is set to fill the bowl with enough fuel so that even at WOT it won't run out of fuel. When you put the bike at an extreme angle or on its side, the float moves and opens the needle/seat and allows more fuel to enter the fuel bowl. (It thinks its low on fuel!!) Meanwhile your excess fuel is filling the intake tract, airbox, cylinder with raw gasoline. Careful, Honda used to build a 3 cylinder streetbike that had this problem, when left on the side kickstand for awhile, the left cylinder would fill full of fuel, then shen the unsuspecting owner tried to fire it up it would bust the piston into little ugly pieces. (Liquid does NOT compress by normal means.. hehehehee)
Anyway, thats why its hard to start.. if youre gonna park on extreme hills, turn the fuel valve off b4 you shut it down, and start it b4 you turn it back on.
Oh, BTW.. its the bouncing and turning of a vehicle and or trailer that causes bikes to flood, same thing.. the float.

 

when a vehicle is leaned to a side the carbarator is flooded. And after being flipped thier is no oil in the egine. So wait and then start. Also you probably havent figured out why it is hard to start in gear!!!!!!!! or maybe while switching to reverse.!?!?!?!?

My Scrambler seems to lay over on one side fairly often. What I do is turn the main valve off, crank for maybe 5 seconds, and it starts.

Thank you gentlemen, I will try those suggestions.
