Most Yamaha 650's from1998 until 2004 can use an NGK standard DPR7EA-9 gapped at around 0.035 inch.
If you prefer the Iridium plugs use DPX7EIX-9 gapped at the same as standard.

The ignitor unit controls the signal from the magnito to the ignition coils. This in turn controls the spark to the spark plugs and also controls the timing of the firing of the spark plugs in proper sequence.
The proper spark plug gap for a 2002 Yamaha YZ250 is .024 inches. New spark plugs usually come pre-gapped, however.
1 and a half
My 1100 Yamaha classic is silver and dark gray,but the dark gray is a special order color for a 1983 Ferrari.

You will need to remove the top chrome rear cover from the rear cyl on the right side. and same on front on the just on the left. they are under these covers. Pull straight out on them.
I'd say check your owner's manual or call your local Yamaha dealer.
Usually the gap should be from .020"-.024"
