What plugs are you guys running in your bikes? And how many miles do you guys put on yours before chaning them?
I've always used NGK plugs. Cars and bikes. Don't know why? :dunno
I have OCD. :cuckoo I do plugs, oil & oil filter every 6000km (~3700miles). Oil and filter by themselves every 3000km (~1800 miles). Air filter every 12,000km.
(The book does say if the bike is used under high stress situations, then certain services should be performed more often, everytime I get cut off by a cage I change the oil :laugh)
