thanks for that!
some questions,

in this image http://i0.wp.com/www.yamahar3racing.com/wp-content/uploads/2015/04/IMG_0178.jpg and http://i0.wp.com/www.yamahar3racing.com/wp-content/uploads/2015/04/IMG_0187.jpg, it says to use socket to remove the bolt, but the bolts are round. what kind of socket fit the bolts?

what is a good length for the socket to fit in the spark plug hole?

The first picture just shows a bolt with a washer, it still uses a regular 6 or 12 point 8mm or 5/16" socket.

The second picture is just a flange bolt, again, it still uses a regular 6 or 12 point socket, 10mm.

I didn't actually remove the spark plugs, but I believe a 6" extension on a spark plug socket will work great.

thanks for that!

ok, after zooming i can see the corners on the bolt, like a flange bolt, however on the first picture,the left side, is more rounded? i guess it is a flange bolt

how do you pull the spark plug wire? just pull it, no twisting like a bolt needed?

Correct, just pull it out.

2 plugs. Best to order as a set of 4, since that's how they're normally sold, and price/unit is a bit cheaper. Also recommend switching to iridium-tipped, since they last a lot longer.
