I did finish making my mudflap extension this weekend. However, I admit, I did requisition this fine piece of tail from my reject bin. I think it was from my DR350, but can't swear to it:
Got a little refinement left to do around the edges so it doesn't look so dorky from the sideview. But I think it will work great. Just needed a little bit of extension....not much. Anxious to get her dirty again.
Follow-up: Works Fantastic! Keeps my backside CLEAN!
