what spark plug?

[mayor west]

i recently bought a blaster with engine mods, most of which i dont know as the seller didnt either, what i do know is that it has a ct 240 cylinder, kiehin carb (not sure what mm) yz 250 coil and full ct pipe. i was wondering what spark plug should be used in this as it was running a standard plug. is this ok?

Unless it's running higher compression and/or advanced timing then just stick with the BR8. If you are running those setups, then you might need a BR9.
