I got a NGK B7HS plug to replace the stock plug. What effects will this have on my motor running?
The 7 in theory is a slightly cooler plug than the 6 or the 5.
Lots of good info here:
Tech Info - Spark Plugs Overview
I run the 7 and like it the best of any plug....
I could not find a NGK 5HS, but did get a 6HS and just put it in yesterday. It seems to be ok, but I have only gone a few miles.
well, the spark plug I have may not be hot enough to burn up the oil right?
In theory yes. BUT it (B7HS) works really good for me. Not one miss.....very smooth and powerful.
I run a B7HV. It's supposed to be non-fouling, so even if it doesn't get hot enough to burn off the oil, it will still spark!
So far, no problems in the four months that I've been using it.
It should be O.K. to run Mr. L.
If you find it fouling after say, six tankfulls, try to find the 5 plug.
rgr that i'll keep it
