How do you change spark plugs on hayabusa?

Answer 1

blow out the cavity with compressed air BEFORE you remove the old plugs....do the plugs (remove/install new) one at a time... Unplug the coil wire first (just a clip you have to squeeze, then unplug) and remove the coil...and if you have the air blow out the cavity good BEFORE you remove the old plug. You'd be surprised how much trash can get in there--- that way you don't take any chances on getting trash in the engine. A standard long spark plug socket(the ones with the rubber grip inside the socket) is the best to use cause it will hold the plug as you remove the old and install the new... Make sure you don't crossthread the new sparkplug when installing...it should thread in all the way with just your fingers turning the socket and extension...(oh yeah, you will need an extension about 6 or 8" long). After you get it finger tight, you will need to snug it on down about another 1/2 to 3/4 turn...Just DON'T overtighten it
