What kind of spark plug does the factory recomend using for an 1986 rm250?

get a service manual. and if you need to know immediatly, do a search. its on the internet somewhere.

thanks for not helping 92 rm125. If anyone else needs to find info about spark plugs check out www.ngk.com. you can look up your exact year, model etc.
