I use NGK BP7ES in the BMW R75/5. With the BSA I now have quite a few NGK B7ES plugs. The only difference I can see is that the centre electrode on the B7ES is shorter.

Can I put the B7ES plugs in the R75/5, with that shorter electrode?

(the one in the picture is “6” - that’s only the heat range, rest stays the same)
