Which Spark Plug?

[terry]

Hi everyone

Can you help me with replacement spark plugs.

I have a 1989 R4 TL, 1108cc, LHD from Spain.

The current plugs are Bosch WR5BC. I cannot seem to track down any of these. I have tried to cross reference these on Spark Plug cross reference site but are unsure what would be best. For information, I attach 2 pics of the identification plates on my engine and bulkhead.

Thanks in advance, Terry

Your Spanish build FASA engine 688 7/91 corresponds to a 688 D7/12 so the spark plugs should be Champion L92YC or NGK BP6HS
