I knew it'd only be a matter of time before our resident Peanut Gallery piped up w/ a wise crack... The stretch of tarmac I did that on was pretty damn flat, I'll have you know.
It was an old favorite that I frequently took most of my bikes on...
Myself, I enjoy doing that kind of work...especially if you've got an array of new parts for replacement. Inline 4's or parallel twins/triples are much more pleasant to deal with vs. wrestling w/ V4 carbs, which can sometimes be a real bitch.
Cool bike....reminds me of my Dad's '78 CB750k. He eventually gave it to my brother who's a wizard w/ a wrench. He pulled the head, gave it a hone w/ some fresh rings & a new gasket...it ran like a champ after the that.
