Recommended Posts

10 is a cold plug for your bike. I ran BR8ES in our 85s. I would not go any lower than an 8 in the RM85. Remember (and this will be on the test) in NGK plugs a 10 is colder heat range and it gets hotter as the numbers go down. A 7 may burn a hole in the center of the piston.

Your little white stuff is carbon. Sounds like you don't change the plug very often.

Only $5 bucks for a plug, go buy a new one and stick in it. plus put some gas in it so your not banging your head against the wall over nothing.
