The Green Spark Plug company Dave. I buy them by the box full.
The official one for the 500 is X22ES-U (400 is X24 IIRC) but I believe X24 may be a better plug due to todays fuels. Can't say for sure as I haven't fitted any yet until the bikes on the road, hopefully later this year or early next year.
Excellent, thanks Ken👍
