    1998 GP1200 Best Spark Plugs?


    I have a stock GP1200 currently running BR8HS NGK plugs. The manual, and a sticker on the manifold both say BR8HS plugs are correct. Doing some research around the forums, I see that some people are using BR8ES, and some are using BR7HS, citing better fuel economy/performance, etc. I can't find a definitive answer anywhere though, on which plugs are actually best and safest for the GP engine.

    Any thoughts?


    EDIT: Sorry, just realized I posted in wrong forum..please move, thanks!
