We can repair your damaged threads not only on your Bultaco, but on a wide variety of 2-stroke brands. A damaged thread doesn't have to mean bunking the part or the bike!
We'll repair damaged holes with a heli-coil/time-sert repair part and we can repair a wide variety of threaded holes (hold the jokes!) from 4mm to 20mm in size.
