Rhys Mann Posted January 8 Share Posted January 8 Can anyone provide the torque setting and socket size required for replacing Sigma spark plugs on a Road Sport 125? I've been searching online but haven't found any information. Thanks in advance! Link to comment Share on other sites More sharing options...

StevehS3 Posted January 9 Share Posted January 9 I asked CC about gapping for my 310R and they said they fit them straight out of the box without changing the gap. They also said the coils were so good it wasn’t critical anyway. Link to comment Share on other sites More sharing options...

John Vine Posted January 9 Share Posted January 9 (edited) Or, if you like nice tools, this long magnetic socket. JV Edited January 10 by John Vine To correct link (wrong socket!) Link to comment Share on other sites More sharing options...
Rhys Mann Posted January 10 Author Share Posted January 10 Thanks John will get that one as it looks fool proof! 😁👍 Link to comment Share on other sites More sharing options...
OldAndrewE Posted January 10 Share Posted January 10 Just be careful, John's link brings up the 14 mm version. You apparently need the 10 mm version Link to comment Share on other sites More sharing options...

The_Dr Posted January 10 Share Posted January 10 I replaced my original factory plugs with the Iridium race ones after 12 months on my 270/275 Sigma. They seem better quality, and I didn't change the gap. No issues at all. Link to comment Share on other sites More sharing options...
