just got my sp 700 and I've been going over it checking everything out. decided to pull the plugs out. they are champion plugs and were pretty black. I cleaned them off and it made a noticable difference. I got some autolite plugs for it but haven't had a chance to run it till this afternoon. what kind of plugs do you guys run? what's the gap suppose to be? my dad had been running ngk plugs in his artic cat and I changed it out to an autolite and it runs fine. I personnaly don't see the need to pay $6.99 per plug when I can get em for $1.59 at the auto parts store.
