A friend has a dyno, and just loves to see what every wheeler he sees will dyno at. While mentioning putting my '07 Sportsman on the dyno on another forum somebody said to be carefull because Polaris with 4 WD have been known to go into 4X4 by them selves on high speed dyno runs. Anybody hear of this? I'm thinking just like a negligent discharge with a firearm, somebody accidentally pushed the switch into the AWD position while on the dyno.
Probably a real interesting launch when it hooked up!

 

If the springs that hold the rollers in (inside the hillard clutch) were to fail. Four wheel drive would engage. you could remove the front drive shaft. But also CVT don't chassis dyno. I guess there is a secondary helix available to stop it from backshifting when the load is applied. HPD has one I think.
