I would really like an aluminum chain gaurd that will protect the underside of the bike from lube fly-off while still being open on the outer vertical side to allow easy lubing of the chain. I am making a prototype out of the stock chaingaurd, but it would be more structurally sound and nicer looking if it was machined (or simply bent) out of aluminum. I don't have those capabilities at the moment

Sort of like

And a luggage rack for the back of 08-09. I think the 07 racks may fit with some modification or an adapter, but I havent been able to get my hands on any yet.
