As I had mentioned earlier, I recently bought a 94 K75 S. The bike has about 46K, and is in generally nice shape. I would like to paint the black injector shield, due to a slight color fade, or scratch. The shield appears to be made of some type of plastic. Anyone have a good rattlecan paint suggestion? Thanks.

Krylon 1613 Semi Flat Black.

Great, I assume that that is a very close match to the OEM color? my intent is to keep it looking as stock as possible.

Thanks.

Very good match.

If you want to do a good job do the following prep:

Wash with dish detergent, dry

Wipe down with clean rag soaked with rubbing alcohol

Scuff with 600 grit wet or dry(dull the surface)

Spray with adhesion promoter(follow directions on the can) don't trust the paint to stick to flexible plastic without this stuff

Prime with light gray hi build sanding primer(follow directions on the can)

Carefully sand with 320, avoid sanding through the primer

Wipe again with rubbing alcohol

Apply 3-4 light coats of the finish(follow directions for recoat and drying time time)

Not sure what an injector cover is on a K75S, neither of mine has one.

In the attached pic, Its the black cover that is just above the left valve cover. Apparently, it was an OEM part on the K75 S Dakar Yellow.

The injector cover was a part not exclusive to your model though. I have one on my plebeian K75. Onlookers are awed by its effect on left-side engine aesthetics. :giggles

Interesting, not on mine.

I have a new one for a K100 with no hardware if anybody is interested. Email me.

The cover would be a hinderance in Queensland's summer. The only way I finally cured the vaporizing fuel rail problem was to fit a reflective heat shield under the rail.

These were made by CC products in California. Not sure if they are still available. I never had any heat related issues in the US.

Martin · « **Reply #14 on:** May 08, 2019, 07:42:10 PM »

We get 35C-40C+ but what makes it worse is being stuck in slow moving traffic. The return line to the tank used to soften up and crimp over. A better quality hose a Unicoil and the heat shield have finally fixed the vaporization.

Regards Martin.

I had that CC injector cover long ago, it got stress cracks and didn't really serve any purpose other than hiding some bits. Even rarer is the CC spark plug cover, replaces the BMW plate with an aluminum air scoop to cool the plugs. Their hype at the time was that this was a hot spot on the K engine. There was some truth to this, a motorcycle magazine had done a series of heat imaging photos of various engines and the spark plug area of the K bike's was distinctly warmer, but nowhere near as hot as most spots of an air cooled engine.

I had a couple of the plug covers also. I may still have one. I will dig through some boxes. If I still do, I will post a pic.

So that cover was an aftermarket item; that explains why my Dakar Yeller 75S didn't have one.

Speaking of the 1994 Dakar yellow K75 S, is there anything definitive regarding the actual production number of the these?
The gentleman who sold me this, said that he had understood 100 yellow versions were imported in 1994.
