I just bought an 06 yz125 second hand 2 weeks ago or so. I accidentally mixed the fuel a bit too rich, and fouled the plug. It had an NGK BR9ES in it, But the guy I bought it off of gave me four new B9EG plugs. I'm not sure if its okay to run the B9EG plugs, or should I get another BR9ES? Or another type of plug... Thanks for the help in advance!
