Correct spark plugs for 1988 Force 125?

[Darkhorse1201]

I am trying to find out what the correct and/ or the best spark plugs are for a 1988 Force 125? I don't know the serial number offhand but the current plugs have no electrode like a spark plug that you would put in a car. It just has a center button. Are these right or can I use a plug with a side electrode? Any part numbers would be helpful. Thanks in advance for your help!

Champion UL18V or NGK BUHX are the correct plugs.

These are known as "surface gap" or "gapless" sparkplugs.

Easy to clean, less fouling.
