I agree, Honda's GN4 is a good oil and I would also use it. Just out of curiosity, if given the choice between GN4 (a conventional oil) at $6 a qt, or Super Tech motorcycle oil (full syn) at $5 a qt, which would you choose?As far as conventional goes the Honda GN4 is really some of the best you can get and I would have no issue running that in anything of mine.
