Need to do put some new spark plugs in my F3, I no longer have the toolkit that came with the bike. Bought it without one sadly.

What size spark plug socket do I need?

I did a search and found the tips I need to access them, but tried a 5/8 socket and seems big.

Thks.

 

If im not wrong its 16mm ....

 

Well after talking with two dealerships, Santa Barbara Honda said that she just checked the manual at it is a 14mm plug. Then as a second reference the other dealership(huntington beach) said it was definetely a 16mm. Funny enough after trying the other plugs, I learned they perfectly fit the 5/8th I was using BUT the one plug which I first tried is actually stripped and that is why it felt like the socket was too large and was just spinning around the plug. So after two turns I could tell soemthing was not right and brought it into the shop.

 

Well u know, 5/8 is slightly bigger than 16mm so its possible that who ever had the bike before stripped it by attemping to remove a tight plug with it
