Spark Plugs and Belt

[Snoman69]

What spark plugs does the Pro RMK use? Also, what is everyone getting for spare belts?

TIA

Belt is a 1115 but when I ordered my helix for the TEAM Tied secondary from RKT, they said they were getting lower belt temps with the 1122 belt. Plugs are BPR9ES. I am running the Iridium version of BPR9EIX.
