First of all this atv is a animal. Power is unbelievable. Down side.I have 8 hours on this machine. Both front and rear brakes squeak when comming to a stop. I am getting a power train harmonic noise is sounds like this wa wa wa wa.Now in the lest 2 hours in high gear I am getting a high pitch whine it sound like a blower on a car. It does not do it in low gear. All imput greatley appreciated. Thanks. Bob
