Hear is the rear flap i installed in the same spot and used the same holes as the stock. It keeps the dirt and dust off the motor as well as out of the front sprocket. You can see the difference on the chain gaurd in front and behind the gaurd. It really works well.
This is the front i made to keep stufff from hitting my head pipe and to limit the debris on the motor.
I thought maybe i would put one of my ideas in here beings i have taken quit a few off this forum.
