Trumpet 216 Posted January 19, 2018 Share Posted January 19, 2018 (edited) False economy to change plugs early. The older Bikes had a, "wasted spark", due to the simple ignition system. Moderm bikes do not. Plugs last twice as long as they used to. Edited January 19, 2018 by Trumpet Link to post
Slowboy 20,425 Posted January 20, 2018 Share Posted January 20, 2018 15 hours ago, Tex said: How many miles in total, Gordon? The plugs are good for at least 30K. Very true, when I changed mine at 28k and four years, the old ones were still within the specification on the gap. I bet they had another 10k in them at least. 1 Link to post
embee 7,288 Posted January 20, 2018 Share Posted January 20, 2018 I expect 50k miles from the NC precious metal plugs. Erosion rates are closely linked to RPM. Many cars use plugs of this design type for 100k mile replacement intervals. Link to post
