Iridium Spark Plugs

Read This; it's from NGK's site.

totaly awesome bro. straight to the point. thnx
oh hey and after doing a bunch of research i was looking to get mobile 1 mx4t for my breakin period then switch to synthetic, any thoughts?

and also the place i bought the bike from said to use 15w-30 and everyone else on this site says they use 10w-30 or 10w-40. what should i use?

Mobil 1 is a good quality oil. Always use the highest quality stuff you can afford; it's the lifeblood of your motor. 15w30 or 10w40 should be fine.

dude sweet thank a million. id didnt want to walk in that place and not know what to get.

any oil is good as long as its motorcycle oil non syn for break in and its your choice syn or not after i like good qaulity oil like honda or mobil 1 and i use 10w40 like most people the ngk iridium spark plug is cr7hix they should have them at any autoparts store

I got a meaty engine and 10/40 mobil 1 has never done me wrong!

oh nice x18#1. what i really needed was the part number for that spark plug thnx bro im going to get one today for sure. and its funny cause they didnt have a lot of selection as far as the oil goes, and i endded up getting the same kind 2manyminis just mentioned lol. right on dude the things so much fun. oh hey so as far as locktight goes, im pretty much just looking to tighten down all exterior bolts like.... handle bars, brake and cluch levers and such?
