    I picked up a kawasaki motor that once warm has a hard time starting. I believe it is the plugs. The ones that are in there are nkk bpr6es. I think the heat range is too cold and think it should be a bpr4es. Can anyone confirm the correct plug for the engine.

    Without checking my reference, I think BPR4ES is the correct plug. Check NGK's website to confirm. You may have other problems that are contributing to your hard start.

    Yes NGK BPR4ES is in my book for a FH721v
