The heading of your posts asks bout plugs for the 17000, I can't comment on that model (is it a martian model)...LOL.
The 1700's have a damn fine spark plug, both in design and materials used. It is of the "projected tip" design which in my testing offers advantages over non projected tip plugs. It also utilizes Iridium for the center electrode, Iridium is a very hard material and NOT subject to electrode erosion like copper or platinum plugs. The plug is quite an unusual plug in that it is a 1" reach, 99% of skoots are 3/4" reach.
You WILL NOT find a better plug due to all of the above mentioned aspects.
Also, refer to the maintenance section in your owner's manual, it has LOTS of basic info and Kawi suggests replacing the plugs at 30,000 miles. I have seen plugs with as much as 23,000 mls and they were in no way anywhere near needing replacement. Forget about them until then.
