BR8ES instead of BR8ES-11

[Killerpirate]

Hello, i am changjng the plugs on my Yamaha gp1300r, and i still have 3 BR8ES laying around. Fsctory manual says they need BR8ES-11. Can i use the BR8ES instead of the BR8ES-11? Or will it hurt the motor?
Whats the difference anyway?

The last two numbers represent the gap set at the factory, in this case it would be 1.1 millimetres. I believe most stock plugs are gapped at around .7 to .8 millimetres from NGK (for motorcycle applications).

Reset the gap to what Yamaha recommends and you’ll be golden.

You mean just bent the tip a little inwards? How do i do this and is there risk that the tips break during jetskiing once i bent them?

There’s a multitude of tools available to set spark plug gap...take your pick. The materials used in plug manufacture allow for gap alteration without damage - just don’t be a crazed animal when doing the deed.
