SF1 spark plugs

[harpmeister]

SF1 in standard state of tune, what plugs would you recommend NGK  BP8ES or NGK. BP9ES

Thanks

Not P (protruding electrode) plugs. B9ES of you ride hard, B8ES if you like to putter. I have raced on 8s so they are ok but you have less margin. A good motor won?t foul 9s but a worn one might.

Didn't think the BP was right but was just going by what was in the Laverda Paradies catalogue.

BPs were recommended by NGK-List for 750s with the "small" engine, i.e.
til 72.
