2013年2月5日 · on ngk's, the lower the number, the hotter the plug. ideally, you want to run the hottest plug possible, without causing pre-detonation, meltdowns, etc. in southern california, i ride B6's on my streetbike in the winter and B7's in the summer. usually. depending on how cold it gets, or how lazy i am. on my modified race bikes, i run B8's, 'cause they're operating at hi temps all the time. in ...

2008年10月27日 · SBP was able to get a bulk buy on NGK BP6HS spark plugs. This plug is an extended tip, high perf version of the NGK B6HS. All other characteristics are the same as NGK B6HS. We've been thinking about this plug awhile but we were concerned about the extended tip.

2008年8月23日 · For NGK spark plugs there is a simple rule of thumb: Low heat rating number (for inst. BP4ES) "Hot spark plug". high heat intake due to long insulator tip. High heat rating number (for inst. BP8ES) "Cold spark plug". Low heat intake, due to short insulator tip.

2011年4月23日 · NGK Iridium plugs have 1 ground electrode. Because of the cost of iridium the center post is very thin. NGK says not to gap the plugs because the center electrode will bust off. Iridium is a brittle metal. They come pre-gapped to .031, good enough for these bikes. The compression comes from having a Puch Hi-Compression head from Treatland.tv.

2010年4月9日 · By far the most common plug used to replace stock is the NGK B6HS, the NGK BPR6HIX Aaron recommended is the fancy iridium one, the BP7HS is an extended tip plug with a cool heat range Last edited: Apr 9, 2010

2008年7月22日 · .20 to.25 should be the gap.Throw away the stock plug and replace with a NGK B6HS plug, If you continue to use the stock plug the electrode may break off and cause damage inside the cylinder. Last edited: Nov 16, 2008

2011年3月14日 · The NGK B6HS is the hottest running, good for cold climates. If you want a cooler plug in summer, go with the NGK B7HS. If you live in Phoenix, run the NGK B8HS. It's for the hottest ambient temperatures.

2011年11月30日 · I noticed that the original spark plug of Chinese manufacture that was in my 66cc engine, has about a 1/2" reach (threaded portion). I replaced this spark plug with a NGK B6HS as one that was recommended on this forum with a similar reach. I noticed as I inserted this spark plug into the head, that it appears to have about 3/4" of thread.

2008年1月13日 · My first NGK B6HS and the stock plug are so soaked and fouled from the super rich conditions that they gave up the ghost. It probably didn't help that the aluminum anti-seize was washed down and around as well. I'm convinced a B6HS is not the best plug for cold, wet conditions and first start/tuning conditions. I may return to it in the summer ...
