Do I really need this stuff?

[thelonius]

I have exhausted myself searching this forum and the internet for the proper spark plug for this bike. This info was conveniently omitted from my GG owners manual as well. This last part I do not understand. The plug in my bike now is a B8ES. Is this the right plug?

[SpeedyManiac]

Should be a BR8ES or BR8EIX, I think.

My 02 runs nice with the br8es, runs even better with a br8eg

Hey Speedy,

If its not too much trouble post some pics of your rad guards with bracing to the frame sounds beefy.

Thelonius,

BR8ES or B8ES, the only difference is the "R" it mean resustant, that spark plug will last more in any case of having the bike too reach or not. Best way to find out if your bike is running well, run on it, then look at the ceramic of the plug, if it is brown you doing well, if it is gray you need to fix up your jetting.

Many spark plugs work well, just understand the meaning of the numbers and letters, you can contact the manufacture byu email or look in www.en.wikipedia.org, or google it.

You will find funcy plugs, with gold, silver, etc... starters, some very expensive some other not that much.

Good luck, for finding the best for you, the once you are using are fine, fits most bikes.

Cheers,

Gus
