I just wanted to gather some real information on the stator failures on M series sleds.
For the guys that fix there own stuff what are you finding for failures= injection coil, charge coils, lighting coil, or fuel pump coil?
Here is my experience this one has bit me in the *** for a long time.
From what I gather particularly on 07-08 sleds the injection coils were a problem cat updated the stator in 09 probably due to a known issue with these?
This may help some I've found some issues were the sled starts, runs perfect, can ride the road, trail, flats, small hills, ect were there is no prolonged wide open throttle and there is no issues at all with the sled. Take it up in the mountains were there is long steep climbs then the issue starts= the machine will start to sputter then you turn out coast to the bottom and have the classic low idle, give it gas and it dies. Now it won't restart no matter how many times you pull on it until 20-30 minuets go by were the stator finally cools off and it starts up like nothing happened :face-icon-.small-con . And sometimes it will start a little here and then still die everytime gas is given sometimes you can feather the throttle and it will go but run like crap.
Now add a fuel box for either a pipe or turbo you increase the pulse width of the injectors working the charge coil harder and it now happens more often, you see the classic lean condition at the top of a pull sled sputters/pops/wide band goes lean and you coast to the bottom with the above issue. You flip your temp sensor bypass switch the sled does start but barely but the problem does not fully go away until the sled/stator has time to cool.
