Hi,

Just a quick question, which size of spark plug socket do I need for my R1 plugs?

Doesn't look like there's a lot of room down there for a socket to fit, I'm guessing I'll need quite a slim one, can anyone recommend one?

Thanks,
Jek

The one that comes with the bike toolkit is best for the job.

Cheers, I didn't get any tools with my engine but I'll have a look on ebay.
