I did find the longer version but was afraid it would be too long and hit the piston. I will go get one and turn the motor over slowly to see how it works.nondisclosed_email@example.com (Lee Bryant)Thu, 11 Dec 2008 19:38:59 +0000 Re: spark plug crossover?https://bfujirabbit.runboard.com/p353,from=rss#post353https://bfujirabbit.runboard.com/p353,from=rss#post353NGK's naming conventions are here: NGK numbers decoded So apparently "B6" only tells you that it has a 14mm thread and the heat range is 6. This leaves a lot of other variables like thread reach and composition of tip. On scooterbbs, someone several years ago reported successfully running B7HS, which would be a slightly colder plug that sticks slightly farther into the combustion chamber (12.7mm instead of 9.5mm reach). The S just means "standard electrode". Assuming the piston won't smack into the plug if the plug sticks an extra 3mm into the combustion chamber, a B6HS should be fine. It also appears that many of the 2-stroke Vespas run B6HS plugs as stock, so they should be easy to find. B-6S or B6S should be the same as B6 (the "S" just means standard tip). I see numerous sources on the web... As for other brands, I've pretty much gone over to all NGK. When I had an old Honda motorcycle with an iffy charging system, the NGKs lasted far longer before fouling than Denso or Champion plugs, so I've been sold on NGK ever since.nondisclosed_email@example.com (shaneb)Thu, 11 Dec 2008 14:54:30 +0000 spark plug crossover?https://bfujirabbit.runboard.com/p347,from=rss#post347https://bfujirabbit.runboard.com/p347,from=rss#post347I am having trouble getting a new spark plug for my 601 superflow. the plug in it is a NGK B 6 .
