I am looking to replace the plugs on my bike in a process to help eliminate some gremlins and satisfy myself. I have the Haynes manual and that states Champion RA6HC plugs with a 0.6mm gap. NGK states Iridium DCR8EIX at 0.7mm and seems to be the more common suggestion. https://www.ngkpartfinder.co.uk/catalogues/motorcycles/search/plugs/DUCATI/701+-+800cc/750+SS/all/14779/ Any recommendations welcomely received.
