Default Re: SO CAL orange county spark plug heat range-NGK

i run the 6 on most of my bikes, and the 7 on my heavily modded bikes.

a 5 is too hot, so unless you only ride your bike in the winter at night, i wouldn't worry about that one.

if you think your motors running hot with a 6, it'd probably take you 15 minutes to panhandle $2.50 to get a 7...
