Hello, I have 2010 850 with 3000 kms on it and 28 inch mudzillas. I have found that this year my quad feels like the adc is kicking in when going through mud and on flat ground. I am in 4×4 not the hill one. I allways go 4×4 and low gear when bogging. I am going to change my fluids just in case. I had put a new belt on last fall. it does not slip. On hard acceleration in 2wheel I will bring the front end up no problem. any help or suggestions would be great. thank you in advance.
