hey guys i have a NGK B9EG on my 92 LT250r...do you guys think that is too hott of a plug just for like trail riding and stuff???? I was thinkin thats more of a racing plug,
Thx for your help every1

 

A 9 is cooler than an 8.... which means it dissipates heat faster.
I would think a B8ES is a better choice, but I am no expert on the 250 motor.

 

id go with a b9es

 

hey gp i got your instant message and dont go to a 6 to get a colder plug as u asked .....lower the number hotter the plug rem that. also if a 9 is to hot u might want check your jetting. 8 is better running plug in mine but hotter then your 9. good luck and if they even make a 6 dont try it or u might be changing your new piston again ....lol
