Hmmmm, in the boating world...there is a ceremony you have to go through to re-name a boat, lest you bring bad luck upon yourself. I certainly hope this doesn't apply to bikes!!!
Of course, the way "around" that is to incorporate the new name into the old...in this case "Professor Stella Sprout", a.k.a. Stella, for short.
(Why am I thinking old movies now...??? Someone yelling "STELLA!!! STELLA!!!!")
Hmmm....that theory, however, makes "Bad JuJu Professor Sprout" (or better, "Bad Professor JuJu Sprout") seem rather awkward, tho', doesn't it???
Sigh.
I think a smudging ceremony is in order. Or at least, swap some parts around - tire levers, saddle bags, bottle holders, or what have you.
OR.....
You can say...Quit being so superstitious and just enjoy the ride!!!!
