Title: Model 9 spark plugs
Post by: Badgerman on March 11, 2023, 11:18:32 AM
Morning guys, the bike came with a loosely fitted Champion UK 10 spark plug and wondered if that is correct for the 1931 model?

Appreciate the help before a buy a new one.

Thanks
Jamie

Manual recommends Lodge H1, no longer available of course. Try Green Spark Plug company to find nearest equivalent.
