Steering head travel side to side (how to limit)
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
After installing the stock fairing, I noticed that when I turned the handlebar fully left or fully right, that the fairing would hit the tank - not good. This is not an issue while riding, but becomes annoying when maneuvering the bike around the garage, parking, etc.
I had initially thought about performing some surgery on the fairing, but I'm glad I didn't. Instead, I drilled and tapped the solid round bar welded to the front of the frame that serves to limit the steering travel side to side. A 13⁄64 inch drill and a 6 mm × 1 mm tap did the job just fine. A 6 mm × 1 mm × 8 mm bolt screwed in all the way works perfect.
While I performed this modification on my Ambassador, I would never choose to do it again. I've since learned that the cause of the fairing hitting the tank was that I was using an original Moto Guzzi Polizia fairing for a V700 (with it's narrower tank). I should have sourced the proper Moto Guzzi Polizia fairing for later models with the wider tank. I'll leave the information here, but I wanted to clarify that I do not recommend this modification.
