Without removing the rear wheel, I installed a painted tin panel to block the crud thrown atop the rear of the engine from the rear tire. Maybe it will keep my air filter cleaner, too.
Tools, supplies I used:
#8 self tapping screws
2 ea. #10 stainless screws & lock washers
2ea. #10 speed clips
piece of galvanized tin
cardboard & marker
black spray paint
drill w/ 3/16th bit
#2 phillips screwdriver with 12" shank!! (THE most important tool --- without it I would have had to remove the rear wheel, $4 off the $ table at hardware store.)
(With this 12" shank screwdriver held above the tire, the handle will be just short of the rear fender/tail light assembly ---- you can reach the two tabs and
have room for hand to turn the screwdriver to "drill" the hole in the tabs with the self tappers. ....and do the final install with the two stainless mounting screws)
Install one speed clip on ea. tab.
'Start' self tappers in the clip hole....drill a hole through tab with them. Remove screw.
Cut card stock to make a pattern which covers as much as the open gap as you think you need.
Trim tin to match. Paint.
Mark above plastic tabs where the hole is...hold your finished tin up there and use the story marks for the tin. Drill the 2 holes.
Bend tin to angle it away from tire. Test install, then bounce with weight of two riders and roll scoot to check for rubbing. If you slightly over-size holes and do not tighten - you can flex the tin in center away from the tire - then tighten screws. No rubbing.
I was lucky to discover that I could get my hand in there to work a screw driver if I used just the right length screw driver. Too long or too short didn't work for my big hands.
This can probably be made out of an old rubber car floor mat, or a mud slap. Use fender washers.
