Has anyone on here had any issues with NGK plugs breaking down quicker than they should?
Went to go back to work this morning and after eventually getting the bike to start it ran like a total pig.
I cleaned the K&N filter while i was off so backtracked in case i’d kinked a pipe or something but after messing about for a couple of hours trying this and that in the cold i gave up and spoke to my mechanic, and after explaining what i’d already checked he said to try new plugs, regardless of how new my ones were.
My plugs were put in 3000 miles ago and are NGK Iridium with a life expectancy of 40-50K.
I’d kept my old set and once swapped over everythiing ran as sweet as a nut.
I don’t remember ever having a set of plugs fail on me so didn’t actually recognize the symptoms to be honest, so it was a learning curve anyway, but must admit i was not too impressed with them failing that quick.
He did mention that although they still are one of the best brands out there, he has noticed a drop in quality, no doubt due to manfacturers saving a few quid here and there.
Worth knowing in case you encounter any similar issues.
