Ok now as far as taking off the radiator, I think that is a bit extreme. What you want to do is take of the gas tank becuase it is very easy. Once in there take off the air filter cover (good time to change this too) and then the bottom cover tray. You now have a bnch of hoses going every where. You want to color code, number these whatever and remove them, it is only 4. then you have the perfect access to the sparkies. I used a reach magnet to pull out my plugs, but the fuel line sounds like a good idea too. http://www.bossturbo.com/cbr/howto_sparkplugs.shtml This link has some killer photos to help out anyone. Hope this helps!!!!
