So has anyone been able to put a larger radiator in? . Is the radiator a 2 row or 3 row? If not that's not feasible add a remote radiator? We road our HDs to the top of Pikes peak with no problems. Coming down was another story. Rain, sno,hail stoped on side of road for 2 hours before park rangers rescued us . Took us down waited 3 hours they plowed road to our abandoned motorcycles. Fired them up and followed the sno plow down. Found last hotel room in town . Because Interstate was closed because of mudslides. Next day before we got back to campsite . Great trip !!!
