2016年9月22日 · I'm using standard NGK DR8ES-L plugs. My only engine mods are that I re-jetted the carb (main and pilot needle) using the kit from ProCycle, turned the air-fuel screw out about 2.5 turns, and put it in a UNI air filter.

2016年3月8日 · Even though the standard NGK D8E plug was fresh and looked new, I decided to try a new plug and installed a NGK-6681 DR8EIX Iridium IX Spark Plug. NGK 6681 DR8EIX Iridium Spark Plug Totally different bike. Fires right up cold, no warm up required, pulls way stronger through the entire RPM range. We will see how long it lasts!

2024年10月23日 · Check the simple and easy things first to rule out potential problems. Since you went through and cleaned up the carb and fuel system checks out being clean, my gut feeling is not the carb. Also the spark plug type and gap: Type/manufacturer DR8EA (NGK), Gap 0.6 ~ 0.7 mm (0.024 ~ 0.028 in) How many miles are on it?
