Kaz has mentioned a Japanese vendor (afraid i can't remember the name) with the correct test equipment/jig and not sure on the pricings (so not a whole lot of help either way!)
so there you have it, shiny new from Honda (sit down before they tell you the price) D1guy in the US of A, again, be seated, and the Land of the Rising Sun, i suspect seating is also required, but i think I remember it was more reasonable !
