I have no idea but taht ^^^ is a bad idea.

i know.

BR9EG is the standard plug for your bike.

thanks man i really appreciate it.

I'm surprised a car plug even worked for you. The reach of the threads and electrode plus heat range makes me question that it is a car plug. B9ES/EG/EV will all work fine.

yeah and the car spark plug is actually not causeing any problems..i dont think lol

i wouldnt run a car spark plug i dont no how it didnt hit the piston but ok i run br8es or b8es in mine
