Took my 2015 800 xmr out on saturday and got in a bit of a tight spot. The front never went deeper then the fenders but the rear dug out the sand n the rear racks were completly under water. I let off the throttle to engage 4x4 and go in reverse and she shut off. I was able to restart but it took a few seconds and giving it throttle. When i got out n back on dry land i shut her down and opened everything up. Air box, the drain tubes for the airbox and the drain for the cvt and everything was dry. Why did it shut down. I kno my suzuki used to do that when the muffler was underwater at idol, too much back preasure stalling the motor, but once i rejetted it it never did it again.. Is that wat happend here? I would think an 800cc v-twin fuel injected motor wouldnt be effected by the muffler being under water.... Anyone else have this issue. Not going to lie when she shut down my butt hole puckered up tighter then a snare drum hahaha
