...Insert clean rollers. COUNT THEM! 33 x 3mm rollers ...
Voice of experience? Enjoying this thread tremendously.
The Guzzi has a roller bearing big-end but it's not at all like most roller cranks. Instead of a multi-piece crank, the Guzzi has a one-piece crank with a 2-piece connecting rod. The rod and cap are precision machined to serve as the outer race. Clamp rod in vice and coat with thick oil. Insert clean rollers. COUNT THEM! 33 x 3mm rollers are stock. This one has been been over-bored to take 29 x 3.5mm rollers. When the rod is full, lay crank journal in the rod, add more sticky oil and the rest of the rollers. Snug up the cap bolts and roll the crank to align rollers. The manual says to tap and twist the rod until the crank rolls smoothly. Then tighten rod bolts to 28 foot pounds (do not reuse rod bolts). Then use a punch to stake the nuts to the rod bolts (missed the photo).
We need a video of it walking across the garage floor.
Head all ready to reassemble....but how the heck do you compress these springs??? I've tried vice, pliers, a big wrenches, levers, more vices (I'd have a chance with the old springs in the background but the new ones will take off a finger!!!)Gotta do some research. Probably need to make a tool...
When I was originally doing the Lario rehab.. I asked the Kid what to use as a degreaser. He said this stuff. "You can paint over it." I was amazed that there was a water soluble solvent that you could do this.. but he was a pro painter in another lifetime. I spritzed it on, blasted it off with an engine cleaning gun and water.. and painted the engine, transmission, swing arm, rear drive. It's still perfect.. 4 years (from memory) later. I'd recommend it to your attention.

Your image doesn't show up for me. What product is this?
Matchless heavyweight singles use a similar hairpin valve spring. Here is an illustration of the hand tool.
