You have a GT200 (no such thing as a GTS200) which is a great scooter. Mine was purchased used with an NGK CR8EKB (double electrode version of the CR8EB) in it and it ran great. I wasn't sure how long it had been in there so I replaced it with an NGK CR8EIX (iridium) which has worked great as well.

Keep in mind that Iridium plugs are not meant to be gapped by the user. And, as I discovered without knowing this, their gap is very difficult to change.

Nor is any other plug with a platinum coating on the ground electrode. If you bend it to adjust the gap, it will crack and eventually flake off.

Scooter West has a plug for Vespa/Piaggeo bikes 100-500cc.

I know I had asked a shop here about gaping the spark plug as was a big discussion on this board back when your model GT was the "new" bike. I know I had issues with my original spark plug on the '07 LX.

The shop guy said that the technology for spark plugs has advanced so much it's not necessary to do all the extra work. Now, getting the spark plug cable from Scooter West is a great idea especially for the older model.

I believe all the NGKs are gapped within Piaggio spec. I wouldn't mess with it.
