Hey guys I have a 96 125, and it takes a NGK BR9ES, I fouled it from break in cycles. I now want to use this other plug i have. Its a NGK labeled "9" Both the plugs have the same length of threads, But the Firing end sticks out past the threads on the BR9ES, on the "9" It ends before the threads, will this be ok to use? A quck response would help. Thanks guys!
