Ive recently done some mods on my ‘79. Uni pods, Mikes pipes, shorty muffs and some jetting: 137.5 mains and 30 pilots. The bike runs good and starts in 3 kicks or less consistently. I pulled the plugs after maybe 100 miles and noticed the white porcelain around the electrode is a orangish color. Ive never seen this before. My old Plymouth manual with color pics of the plugs says its high speed glazing and to try a colder plug
. Anyone seen this? Further jetting recommended?
