Please Note: You need to run a guard dog sprocket guard cleaner to keep dirt buildup out of the sprocket guard, and you must run a chain guide to keep the chain entering the rear sprocket area straight onto the rear sprocket and to help keep debris out of the rear chain and sprocket guard setup. If you do not do this - you can experience severe engine damage.

Rotor Guard Installation

1. The rotor guard needs to be installed with 4 bolts.

2. It needs to be touching the rotor for proper protection - the rotor will wear into the quard an 1/8 to 1/4 inch.

3. You may need to install washers between the rotor guard and the swingarm on the right side to space it down to get the guard positioned right since the quad uses an eccentric chain adjustment and the axle moves up and down when you adjust the chain.
