Back in 01 My dad bought a Suzuki quadmaster 500 4x4, its been good untill this year. Recently A friend and I went riding. I rode my 400ex he rode the Suzuki. We cut the ride short do to grinding sounds in the trans. Its fully automatic. The tranny heated up considerably, could the breather be clogged, Or a smoked belt? Also has anyone modded a QuadMaster?
