In my experience with Moto Guzzi transmissions, most shifting issues are caused by sloppy, worn linkage components. On the 70s Tontis, the “bent rod, cotter pin” linkage wears and causes false neutrals and miss shifts.
After years of sloppy shift linkage I’ve come up with a simple, clean and durable replacement.
I have assembled a replacement linkage that is a direct bolt on most Tonti framed Guzzis. These spherical rod linkages come, pre-greased with protective rubber boots. One rod end is reverse thread for easy adjustments.
Each linkage comes with a left hand jam nut as well as self locking mounting nuts and can be installed in just a few minutes. I have noticed on some applications that the threaded rods needs to be shortened by about 5 mm at each end. I have included a right hand “chase” nut for cleaning the threads after cutting. I recommend only using one jam nut to prevent binding of the linkage.
Models include:
Other Examples
These link rods come with an adjustable range from 2 3/4 inches to 3 1/4 inches center to center. I had to trim the bolt down 1/4 inch on each end to work on my 850t but I didn’t have to use my T3. Take a measurement of your existing rod. I can trim it for you or you can do that yourself, it’s up to you. I will include the reverse thread jam nut so you can chase the threads after cutting. I only use the one jam nut so the linkage doesn’t bind. I also include 2 6mm nylocks and a standard 6mm nut for thread chasing.
