Question - I have a 1999 Harley Davidson that uses  Champion 6R12 spark plug. Will the 4212 spark plug thread repair kit work for my bike?
Answer - Yes, if it's a first time repair, because the Champion 6R12 spark plug is an M12x1.25mm so the 4212 is the right size. Here's a cross reference for other spark plugs that are also the same size as the 6r12 - Cross reference: NGK DCPR7E, DCPR7EIX, Champion RA8HC,DENSO IXU22, Autolite 4163, 4164, Harley-Davidson 6r12. 
Been repaired before and need an oversized? There's no specific Time Sert "Big Sert" or oversize for 12x1.25mm spark plugs. You can however use the 5212 kit.
