CB500/550 / Re: Plugs fouling at idle« Last post by K2-K6 on Today at 05:07:30 PM »Why not? If you can design for whole numbers you can design for half wayIn my understanding most of us took the D8ES-L heat range for in between 7 and 8. Thats my view of extending the central electrode out into the combustion chamber too. It would allow it to heat more than a straight 8 to raise potential tip temperature, but not as much or as far as a 7 ..... well that's how I visualise it, whether that's true or not. Any arrangement with longer route from porcelain at tip into the surrounding structure SHOULD make the tip retain more temperature .... that's generally what plug design achieves. Wouldn't an 8.5 be called a "9-L" by that description ? 3

CB500/550 / Re: Plugs fouling at idle« Last post by deltarider on Today at 02:14:47 PM »Compare the above to what they gave me as answer, after I took the effort to contact them.The fact that the L was a half grade came from the same reptat suggested d7ev to me, and that man knew how to read plugs My question was: Dear Cust, Here's a question owners of motorcycles that had the NGK D8ES-L sparkplug prescribed, never had answered: Is the D8EA plug, as far as heat range, the same as its predecessor D8ES-L? In addition: Is the D7EA plug just a renamed D7ES, or does the -A suffix ('Special Design') imply the D7ES was indeed modified? Core of our uncertainty is, that we have no clue what the meaning of 'Special Design' is. We realise it may be difficult for you to find the answer. You may have to consult older employees who can remember. Somebody must know. The issue has been debated over and over in various fora around the world (Germany, Holland, France, UK and US) and no NGK chart ever solved the uncertainty. https://www.ngk.com/ngk-spark-plug-numbering-systems And here the answer: Hello, Thank you for contacting us! D8EA had a heat range of 8 and D8ES-L heat range 8.5. The (L) stands for Half Heat Range. As a Distributor for NGK the -A suffix ('Special Design') is still a mystery to us. You will have to contact NGK directly at 1-877-473-6767 ext #1 or www.ngksparkplugs.com they may have more details on this. Personally I find it hard to believe that the D8ES-L has heat range 8.5. Your comments please. 9

Tip: use a little vaseline, silicone oil or similar inside the upper sealing rubber before you screw the HT wire on. That rubber seal is a bit tight and could therefore resist slightly and give you the feeling you are already there, when in fact you're not. Then you would have a bad connection.
