Spark plug

[Blue]

Would it be ok to use a DPR5EA-9 temporarily in place of JR9B in my standard 1127?

To get it running maybe but its way to soft / heat retentive to use for general running - its a #5 whereas the correct plug is #9

Yeah not gonna be riding it, thanks

As above, get away with an 8 or 10
