I changed the plugs today and on getting the old ones out, I noticed that the last person who serviced the bike (before I owned it, I hasten to add) hadn't gapped the plugs - they'd left them with the "out of the box" gap ie: around 1mm+.
What would be the effects of an oversize plug gap?
I gapped the new ones to 0.5 - 0.6mm as per Haynes.
