Hey this is my first post and actual real first problem with my grizzly. Its a 2009 550FI with 600hrs & 6200miles on it. I bought it new and have only done general maintenance(oil changes, clean air filter & greasing IRS) minus cleaning and re-greasing the cvt since its not in the manual i didnt know it needed serviced. That said 2 weeks ago i was out checking out cows in the pasture and crossed the creek like I’ve done hundreds of times didnt notice any issues until heading down the road at close to top speed and i noticed a new noise coming from the engine. It started pretty quiet and every once in while acted like the belt slipped/engine sputter and i lost power. I sent an engine oil sample to the lab results came back normal for my age machine. But now after riding a couple more days the noise is constant and gets louder when reving the throttle. I thought it might be the wet clutch so i removed all parts and covers to get to it but the pads look really good and no grooves in the housing, the oil and pads dont have and indication of the pads slipping and burning. All bearings i have inspected so far seem real good not much play at all. Question is now what? Thanks for any help I can get.
