Tip
I noticed recently that my 02 GS500 with around 4500 mi. maybe wasn't running as good as it use to.
I stopped by the Suzuki shop and picked up some new plugs and WoW!, what a difference. I guess it had gone off song so slowly that I didn't really notice how poorly it was beginning to run. The only thing I noticed on the old plugs was that the left one was a little dark.
More power. Much smoother.
