My question is about my 850 in 4WD. When I have it in 4WD and I turn it left to right and back right to left it feels like something is grinding and it seems it pulls harder when I am making a turn just in 4WD. There is no noise of grinding I can just feel it in the handlebars. It feels a lot different then my 550. And this is all on dry ground. Is it the new close ratio 4WD or is there something wrong ?

Thanks.
