Well...As far as my (Multiple lockups on the way home) experience....It did happen a day after I had gotten my Supersport back from engine mods so it's not entirely out of the question they did not have something put back together right in my case (Not the case of the others lockups though)...And for the question of oil...Yes...There was oil in the tranny of sufficient quantity...Straight 30Weight is was is called for by Avanti...
