I've searched, & couldn't find any mention of a Iridium spark plug. Is it so new that no threads exist? Or is there some reason I shouldn't use iridium? BTW what is the proper gap? Please advise, I already bought the CR8EIX & just want to make sure it's not a mistake to use it. I have a 8 day Trans Am. Trail trip comming up real soon & wanted a new plug for the trip.
Just in case it matters, I have 03' KLX400SR w/ 3x3&DJ kit... The rest of the motor is stock w/ a billet end cap.
