Shall we say that there are various riding styles and opinions on the forum? Some of us would ride well together, but not others. Personally, I don't ride around at 34mph in 6th very often, but regularly do 40mph in 6th and the bike has no problem with it. I don't think most of us care how the rest of us ride for the most part. For instance, I don't care if you never shift into 6th before 65mph. I may think that you're doing it "wrong", but I can't see how it harms me.
As to the 10,500rpm in 4th: There seems to be some anecdotal evidence that the tachs on C14's register high, and that the cutoff is actually closer to 10k rpm. So maybe you aren't stressing the bike as much as you think.
My bike does seem to like cooler weather. A few nights ago it pulled the front wheel on partial throttle as it hit mid-range in first. So maybe all the slow 6th gear riding is good for it.
