+1 on the valve adjustment tool. I bought one as soon as I saw it. Makes "getting the feel" much easier. Fortunately for me my hammers are left-handed...
I've always had good luck with the star-tron, but other things happen; like last night I got the dreaded weak buzz click at the relays. Time to clean and check connections and grounds. If I didn't like the bike so much I would have lost patience with it by now.
My "sedate" black frame burgundy has the vibey clip-on's , and I even crank up the steering damper at higher freeway speeds. I guess I'm becoming the old fart "poser" ( until I get to roads I know)...😅
My burgundy black frame is "Cracklin' Rose" from a wonderful encounter with a beautiful woman, hearing that song, and the noises she makes ( the bike that is) when cooling down...
I was thinking that perhaps the Guzzi singles were inspired by WW1 aircraft engines (Anzani,etc.),and the trend evolved into more cylinders... Just a thought.
