I have a new old stock wr400 which I would like to build into a road special. Has anybody fitted cast wheels, a full lighting system and changed the body and seat panels? What is best for the engine? My Japan contact told me to junk the carb and use a Keihein flat slide but what size? Cost is not a problem as I have some funds tucked away from the wife. Another problem is that the bike is set with 14 inches of ground clearance; the norm on a road bike is about 8 inches. How do I cut it down to size?
