Q- A carbon tail hugger.
A- I've never seen a hugger specifically made for C model. But I'm pretty sure you can use one made for a D and fit it. I think the only modification required is drilling another mounting hole (OEM chain guard's mounting holes are not spaced the same on D and C)
Q- A fender eliminator kit (I think I can do this myself)
A- Yes, you can do it yourself. But very V-E-R-Y careful at not weakening the plastic structure holding the taillight (kind or hard to not...). If not, the taillight molding W-I-L-L break. It is extremely thin LH and RH of taillight and way too easy to break.
Q-Wider mirrors or 50 less pounds on my ass.
A- I can't help much for your ass but here's what I made many years ago on my mirrors (glad to see I'm not alone to think they sucks). I modified the OEM stems by having a piece of aluminum welded to make it longer. I then used putty to get back OEM shape and had them painted black. Now, about 50% of the glass surface can be actually be used to see behing me without having to move my arms or elbows. Prior to this, about 10% of surface was useful. To have more than 50% of the surface to be useful, I think the mirrors will need to be elongated to much that they will become butt ugly or will be too heavy and constantly loose their adjustment under their own weight at each road bump. It was very time consuming but worth it (at least for me...). I think I could have another set already welded but not puttyed/painted...
Don't try to find mirror spacers to be bolted between mirror base and fairing; they are inexistent. I first thought at building some but the angle at which they are mounted make this impossible.
Q-Clear front and or rear tail light lens covers.
A- I suppose you mean clear lenses for the four turn signals? None are available for C model.
Q-Ditto on the brake lens.
A- Here too, no clear brake lens is available for C model.
Q- Center removable luggage rack.
A- Dunno. The only ones I saw where one (nice) home made ones; they where bolted to the grabrail or to the foldable bungee hooks. They probably are after-market sources though but I ignore them. Here, I'm using two Givi bags and a soft seat trunk bag (Chase-Harper).
Q- I really need to work on the wider mirror thing. I have to tuck my elbows in every time to look back.
A- See above
Hope this helps...
