    fh430v? Twin cylinder 15 horse? Just bought the gravely i have been lookin at. Noticed it had a champion j19lm in it, and the book calls for rcj8y. If i am not mistaken the j19lm is slightly hotter, and rcj8y has an extended tip and a resistor, which the other does not have.. Now any reason i havent thought of as to why there would be a j19lm in an almost new motor? The hour meter shows 8 hours, the deck just show dirt no missing paint or nuthin, so it has been used at the dealer, also found out it is a 2003 motor and 2003 frame. So i guess my question is, iis my assumption right in a j19lm is the wrong plug? And that i should make the dealer give me a set of plugs?

    Use only NGK plugs in all your stuff. It will probably be a NGK BPR5ES.

    Your book is right on that plug, If it had j19's in it I would ask your dealer for the right ones. Personally I only run NGK's in Kawasaki's and Honda's.

    NGK is the only brand I'd run in a Kawasaki or Honda as well.

    Yes, Ngk I Can Bet On Them, But It All Really Depands On If Its An Ohv And What Type Of Block (cast Alum. Or Other)

    Just looked at the NGK catalog and it says #BCPR6ES is the proper plug for that engine. You can go to NGK's website and look for yourself for just about any motor,saw,trimmer and many other types!

    that bcp6es is not the right plug. thats a long plug and will possibly hit the valves or piston. it takes a short plug, like a cj8y or ngk bpm6a only the larger engines, 19hp+ use the long reach plugs

    NGK are fine plugs, but to be clear for the record, the factory plug for that Kawasaki FH430V engine is a Champion RCJ8Y.
