Hey guys, I'm new to both the forums and bikes in general. I picked up a 1981 XS 400 Special Heritage back in march and have been fixing it up since. I've come to my last problem before being road ready. Both air screws or pilot jets or idle mix screws (far to many names for them on here) were broken off in the housing. I removed them and I am looking for new ones. I've had no luck online nor at my local yamaha and motorsports shops. Does anyone know where I could fnd a set? They were both larger brass screws that could be adjusted by thumb turning. They sat after the butterfly but before entering the main engine housing. Any help would be greatly appreciated. I'll try to get pics up tomorrow as well. Thanks.
