If I remember the book says to do a few heat cycles and then ride the bike the first half hour at no more than half or 3/4 throttle. After that let's see what she's got! :lol:It's GO TIME!
You'll have to go back and read it.
After the half hour session check the plug . Your gonna have to determine if you need the #9 plug by what the #8 looks like. Trail riding I would think the 8 is good. but you have to look at the plug and the chart in the manual and make a decision.
If you are holding the throttle wide open for more than 30seconds at a time you need the #9 plug.
Hows that for a rule of thumb.
I have seen those things run 30seconds wide open and you need a lot of real estate to be able to do that in!
The heat ranges on the ngk plugs need more heat to reach operating temp the higher the number.
So a b7es is going to get alot hotter (all things being equal) than a b9es
The plug needs to get hot enough to keep most of the oil burnt off and not foul, but cool enough not to burn a hole in your piston!
