B9 is fine. On a 2 stroke it's a good idea to carry a spare on the off chance the plug gets oiled up and stops working but with modern plugs they last a long time. Be careful tightening the plug. How does the scoot run?
I use the same plug no issues

Excuse my ignorance, but why the comment about be careful when tightening a plug?

I only mentioned it as it's so easy to strip threads or cross thread a plug. It's one of the few threads I haven't stripped on a scoot but every time I twist in a new plug, that washer crush thing makes me nervous!oneday wrote:Excuse my ignorance, but why the comment about be careful when tightening a plug?
