That's a cool idea!!! Here's what I did!!! Go to your local home improvement store or hardware store and get a 12" x 24" aluminum tread plate and 4 u-bolts. Cut a hole for the oil drain and u-bolt the plate under the bike. You'll have about an extra 3" in front to bend up in front of the pipe. To reduce vibration, connect a strap from the front to the frame. You'll need to cut out a little for the shifter too. You can either use a jig saw or just grind it. This protects the pipe and the engine from rocks kicking up from the front wheel. I smile every time I hear a "Ting" on the plate while I'm riding, knowing that could have been a nick in my pipe or engine case!!! Total cost: $20 for the aluminum tread plate and $5 for the u-bolts. It took me about 3 hours to do a really nice job, sanding and rounding all the edges. Have fun!!!
