2004 YZ250 Spark plug Issues

[Moto Man26]

Hi everyone!!:) I fouled the plug on my bike today, so I took it out and installed another one... But the plug that was in the bike, is a NGK BR8EG(the one mentioned in the manual), but the new plug that I put in is a NGK B9ES... My question is, Is this plug alright for my bike? Or can it damage the motor? Any help will be appreciated!! Thanks!! :) :ride:

I would take the b9es back and get the BR8EG just to be safe

the higher the number the cooler the plug is, so you won't be damaging anything you'll just be fouling another plug.
