I put my hands on a new Sirio 12TRP that I plan to break-in on my NTC3 this weekend (aaaarggh! very long wait until Sunday
). Any suggestions to this motor?
What plugs are you using with this motor? I currently using Novarrosi plugs (non turbo) ranging from 4 to 6, someones suggests a #5, others a #6... What's your suggestion?.
Planning to use for racing with 16% nitro.
