Moto Morini Restoration
I acquired a 1985 Moto Morini K2 two years ago from a friend in Texas. Moto Morinis are well known in Europe, not so much in the US. They have a long, successful race history as well. I decided to restore this because parts are available and a lot are interchangeabld with Moto Guzzi, Ducati etcetera.
The tank and panels are in great shape, the frame and everything else, not so much, but not unrestorable either. Photo 1: bike as it sat when purchased. It runs very nicely BTW Photo 2: the start of the teardown.

Intially I thought I could do a frame-on resto, but on closer look there was a needed weld on the frame, and rust issues to address. So it was decided to do a complete teardown.
How do you remove a heavy v-twin from a motorcycle frame yourself? You unbolt it, lay it down and pick the frame up over the engine. Photo 1: Engine unbolted, frame laying down. Photo 2: Engine and frame liberated from each other.

While the frame is drying, it is time to address the dirty engine. I cleaned it up with solvent and then used a brass brush to brush out the aluminum. The valve covers and side covers will be removed and painted later.

Backing up a step in the photo sequence. It takes a proprietary wrench to remove the exhaust nut so I had to order that. Once appropriated, easy enough.

Also while waiting for frame to cure, there needed to be an address to the tach. The luminescent paint was starting to flake and powder. I had to carefully remove the bezel, disassemble the gauge, clean it and reassemble it.
Photo 1: Before. Note, the powder residue is not light glare Photo 2: Restored.

Frame cured and engine mounted again. The intake and exhaust ports are covered with Nerf golfballs, a great shop tool.

There were three things that I couldn't do at home: 1) paint the frame, 2) clean the aluminum footpeg mounts and 3) resurface the brakes.
For the aluminum, I sent it to Super Fine Shine here in Ohio and asked them to restore it to original brushed aluminum look, not polished. They returned the parts to me in excellent shape and I then clear satin coated them. These mount the footpegs and they run the shifter from a left-side mount, under the frame to the right side of the engine where the shifter rod comes out of the trans...Morinis used to be "backwards", this was their fix. Before and after photos.

The rear shock are serviceable, but in need of paint. Spring compressor in hand, disassembled, repainted, mounted.

Very nice, keep the pic's coming. What size is the K2? I knew a guy that had a 350 a long time ago...

Very Nice. I was wondering about the status of your Morini. Since you already have the exhaust wrench, it's a moot point, but I used a plumber's flange wrench which I modified to get the nuts off my old 500.
Keep the pics coming.

A little more work done finally, the spring had me put this on hold while I did spring stuff...
I had the forks made by Forking by Frank in Indiana, he can make forks for anything. The original ones were pitted beyond use. I used aircraft paint stripper on the painted parts, prepped and painted them anew and set individual 1/4 inch ball bearings on lower and upper races. Tires/wheels mounted for stability...they will be refreshed as well soon. I also restored the air filter system. New filters and housing mounted to the steed. Photo 1: Forks installed Photo 2: Forks installed closeup Photo 3: Nasty old filters...in the bin Photo 4: New freshened filtration system
