Dyna,
I used sign making vinyl on mine. The self adhesive type. I used a type that is somewhat stretchy, used for lettering emergency vehicles so as to go over rivets etc.
I took the forks out of the triple clamps and cut a piece large enough to cover the entire upper portion of the forks, leaving plenty on the top and bottom.
I then peeled the backing off only slightly for the length of the vinyl and started from top to bottom. Go slowly and work it with your fingers slightly stretching and removing the backing as you go until you have covered the entire upper of the fork. The vinyl is very thin and I easily slid the fork back into the triple clamp and clamped it just tight enough to hold it with the clamp actually clamping on the vinyl.
Then I used a razor (exacto) knife to trim the vinyl that was overrun at the bottom near the dust cover. Then using the triple clamp as a guide, cut around the outside of the fork at the bottom of the upper clamp and the top and bottom of the lower clamp. Then remove the fork and remove the vinyl pieces where the triple clamps actually clamp on the forks.
For the lowers I used a sanding sponge to scuff them and used caliper paint. Be sure to mask everything well and don't paint where the brake calipers actually seat on the fork lowers. I then made some front protectors, again from the same vinyl to put on the front where stones etc. may hit the lowers. Then if they get nicked up I can just heat them with a hair dryer and remove and replace them with new ones.
When you put the forks in for the final time, place the seam towards the inside rear and you never notice it.
Hope you can see all this in my pics., (no comments on how dirty the bike is please LOL).
I know this is lengthy but you can easily do it all in a day and mine as been in place for over 2 years now and still looks good.
Also the vinyl is so slick the bugs/grim, etc, are easy to remove.
Hope this helps,
Lonnie
