What are best spark plugs to get?
Done a search but not found answer, 6R12 according to the manual.

Also what are best rear brake pads?

cheers

Do NOT use 6R12 ................they were subject to a service bulletin years ago as to being part of the cause of holed pistons ..............use genuinne harley plugs as they are as good as any but use 10's not 6's ................. any decent dealer shouldn't even sell you the 6's now .

Plenty of discussion on NGK Iridium plugs, some say they make their bike run better (wouldn't you if you had spent lots of money on them), however others say they make no difference and others say they are more prone to fouling....
