Spark plug help!

[rickyt28]

Just removed my old plugs and started to fit the new ones but ive noticed on the end of the old ones theres a thin screw thread, and on the new ones (iridium upgrades cr9eix) theres a slightly fatter end on them, so the leads wont push on properly?! Ive looked into the ends of the leads with a torch and i can see a small hole with a slotted screwdriver groove either side, has that got anything to do with it?

Oh and another thing, i dropped one of the airbox screws and its landed under what looks to me like the starter motor, i cant get it and its disappeared out of sight. I'm just a bit worried coz it looks like its right near the final drive and chain. Any suggestions??

This might make it a bit clearer..
Do i need to remove the terminal nuts off the new spark plugs, or do i need to remove something from inside the lead?

[rickyt28]

lol sorry, i figured it out, the terminal nut just unscrews off the top of the plug.

Ya learn sumat new everyday!

I dropped an airbox screw down there before. Got it by taking the front sprocket cover off and poking it through

Yeah sorted the plugs. I got the bolt by fishing around with a magnet on a stick lol
