1973 BMW R75/5 Rebuild: Grover’s First Ride Around the Block

The rebuild is finished and I documented the final assembly process in this write-up.

On the Fourth of July, “Grover” was ready for his first ride since he was stored away seven years ago in my friends barn.

Grover On His Way to My New Shop 18 Months Ago

HereĀ is a short video of the first 3 mile “around the block” ride on Grover. You can’t see the s&*$ eating grin on my face, but it’s there šŸ™‚

Here are some photos I took before the ride when I took the bike out of the shop for the first time in 18 months.

1973 BMW R75/5 Rebuild: Final Assembly and Project Completion

I completed the rebuild project after 18 months. “Grover” is finally back together again and looking good as new šŸ™‚

I documented the final assembly steps in this write-up.

I will post about the “first ride” around the block separately and include a short video.

Stay tuned.

And yes, it’s a let down to be done, but there is a sense of satisfaction at what I learned along the way and the problems I figured out how to solve. I think that’s the addication in rebuilding these old airheads.

Here are some “glossy” photos of the completed rebuild.

1973 R75/5 Rebuild: Assembling Windjammer II Fairing

I Ā did a number of projects on the Windjammer II fairing: disassembled the fairing, repaired cracks, removed the old paint, painted it toĀ match the bike (Monza, or Metallic Blue),Ā and paintedĀ pinstripes .You can read about that work in theseĀ write-ups.

Now it’sĀ time to assemble the fairing again and mount it on the bike. I wrote-up how I did this work here.

It required installing the headlight assembly, the side reflectors, new chome edge trim, the Vetter name plate, removing old decals and deep scratches from the windscreenĀ and modifying the fairing bracket so it doesn’t gouge the paint on the frame (I hope).

Here are a couple pictures from the write-up.

1973 R75/5 Rebuild: Painting Pinstripes & Side Cover Stripes

I’m not a professional painter nor have I ever done pinstripes. So, that’s the reason I’ve done all the paint work myself so I can learn how to do it. Ā Here are two write-ups on how I painted the pinstripes and the side covers.

I had some “adventures” along the way when I tried painting the pinstripes. Ā I did use a pinstripe brush but opted for “training wheels” and used a pinstripe stencil tape so all I had to do was paint between the lines. Ā I have a new found respect for the fine art of painting free hand pinstripes.

I also painted the horizontal stripes on the chrome side covers. Ā I tried the Monza Blue paint from Glausrit but I didn’t like how that looked. So, I tried some Dupli-Color rattle can paint and they look better. Ā I may try to paint the side covers yet again as I’m not sure to best handle the curved edges. But they look pretty nice.

Here are a couple of pictures from the write-ups.

1973 R75/5 Rebuild: Painting Tank, Fenders, Windjammer & Tail Light

I’ve completedĀ painting the tank, fenders, Windjammer fairing and the rear tail light assembly.

Here is the link to the write-up on this work.

I did this starting from setting up the High VolumeĀ Low PressureĀ (HVLP) paint guns I bought through buffing and polishing the clear coat in this write-up. I had problems getting the HVLP gun to apply the primer, but found the answer to getting the gun to atomize properly. Ā It works different than the older syphon feed style gun I had used before. Ā I finally found some good videos about how to set up an HVLP gun and spraying techniques. Things went a lot smoother after that.

You can see how bad the second coat of primer was in these pictures.

And here is the front fender and tank after polishing the clear coat along with a picture of the painted tail light assembly. I’m pleased with the outcome although it took over 2 months to get his part of the project done. I have nothing but admiration for those who make a living painting, particularly if they paint motorcycle parts.

I still need to sand, buff and polish the clear coat on the fairing and to add the pin stripes. I’ll write-up how I did paint the pin stripes when I get that done.
