If you havint changed the oil when needed or used the wrong oil, then the problum is the cam lobe is gone!! this happened to me.

The two exhaust valves share one lobe on the cam, its common for that lobe to ware down to the point that its not opening the valves,

My lobe was rounded off!!

you have to take off the gas tank, up by the sparkplug is the valve cover take that off and try to start,, if you dont see the valves on bottom moving then its the cam,

new cam = $250

if you do it your self make sure to tie the cam gear to the frame so the timing chain dont skip a touth,

if you find out that it is the cam and need some more tips e-mail me @ tech@gofast-computers.com

Tranny works, shifter wont shift the gears. how to fix?


My 2005 Polaris ATP 500 requires I depress the right foot brake while shifting into reverse or down into low range. Perhaps some adjustment on the foot brake to make this work. Also check linkage to make sure it is not binding. Others say if the idle speed is too high, you may not be able to shift. Try shifting with the engine off to see if it goes into the gears, using the foot brake. If yes, try again while at low idle speed.
