Hi, new to forum. I've browsed on here for troubleshooting help while building my bike. I read about spark plugs, and everyone says to get an NGK B6HS. Problem is that the hex on the plug is apparently 13/16" (didn't measure it myself, but that's what the specs say), while the one I have (Z8C) is around 3/4". I compared them and it is noticeably bigger. That's a problem because number one, I don't have a wrench that is 13/16". Second, with the bigger hex I don't know if I have the clearance around the plug to tighten it down. Also, the NGK has a longer reach, which worries me. I've also read about the E3.10 plug which is also 13/16" and has an even longer reach. The plugs are obviously not the same specs. What gives?
Edit: Actually I just found a thread of someone having the same problem. He says there's not enough room to tighten in down on the YD 100 engine. How do I find a b6hs with a 3/4" hex?
