Another question (for the 97 ZRT800).
I was told I should use NGK BR9ES instead of NKG BR9ES. Does it make a difference?

I can't tell the difference between BR9ES and BR9ES I use 1 of each in my sled LOL . I think you made a typo...

What plug came with the sled? I think that the number "9" is the heat range of the plug. I don't remember if a lower number is a lower or higher heat, I think that it is hotter. Ask your a dealer what plug goes in that machine, and I would stick with NGK my dad's 1998 700 RMK went over 5000 miles with the original set of plugs.

Yikes!I mean't I was told to use BR9ES instead of BR8ES

The plug will be a bit cooler and may or may not run better. Don't use plugs to correct rich or lean mixtures. With going cooler the worst that can happen is a fouled plug.

Seeing it's a cat, AC has a special plug through NGK for high output ignitions. I think it's the BR*EYA.

I'm pretty sure the slead came with 9's I would suggest staying with NGK BR9EYA's
the manufactures spent hundreds of thousands of dollars designing their machine to run well I doubt they over looked the spark plug.

You're right In Alaska...as the number on the plug decreases the heat range increases.

For the performance rider, run the Br9 plug. If you're going to be riding the slow lane run the Br8.
