Well ,if you are lucky enough to own a BSA Lightning,  Thunderbolt or other BSA motorcycle... here it is...a set ( 1 left, 1 right)  of new ignition points  for your bike. Get your bike running right! New clean, unworn ignition points are very important for correct timing of your spark and quality of spark. Your key to a well running bike: ignition points!  Great if you are riding or restoring a BSA. An essential tune-up item. These are for the bikes made between , 1963, 1964, 1965, 1966, 1967. These are for the Lucas 4CA Points plate and are correct replacement for Lucas part # 54415803. These don't turn up that often...and if your local shop does have them..they are much more $$.  These are high quality Japanese made ignition points are a precision fit.  Having new strong springs really is an improvement on the old points too...as less points float at higher revs. You get 2 points (one for each cylinder)  These fit also fit the C15  (250cc) , B40 (350 cc), A50 (500 cc) A65 (650 cc).
