Posted by Nick V 29-01-14 at UKGSer site.Alternatives:Denso IU27D;NGK CR9EIX-iridium tiped;NGK CR9E-non iridium.For installation have to use 16mm tube socket with max.outer diameter of 22mm.This socket FITS the spark plug hole.The MAR8B-JDS closest match is CR8EKB (commonly available).
This gentleman did this, so this is a fact.

I did not try out these sparkplugs yet,synce I got 16 of MAR8B-JDS,so I am ok for a while.Just posted this, to help anyone in need for spark plugs for camhead r12r/gs/rt.It should work.It worked well for South African gentleman mentioned above.

I believe these are one heat range colder than stock. You may have to use IU24 and CR8 to match stock heat range.
