The exaggerated point was that the rules are much more lax in North America."Pre-65" isn't even necessarilly the class name or cutoff period for older classic trials bikes and the rules vary depending on the organization you are competing with.Your Mikuni carb will probably be fine, along with other later components as the rules are no where as tight as in UK or European classic events.
