noone recommends it, wether theres a reason is kind of irrelevant, why would you keep switching back and forth anyhow, seems just rather stupid to me, i can understand if your bike acts different or slips or something to switch back but otherwise theres no point. im sure its not the best idea to do wether theres harm in it or not. and your motor wouldnt pop from changing oils unless you went from one weight to an extreme other.
