[bkolman]

Hello

A friend at work races shifter carts, his team has a sponsor ship with NGK he gave me a some new spark plug to run in

My 05 cr250r saying that theses are the best plugs NGK 6254e-105 on the dyno for them. I have never heard of theses plugs does any one have a info on them...?

Interesting but NGK doesn’t list it as recomended for motorcycles or carts, They just list it in the general race series plug.

But they list the BR8EG for the CR250 instead of the BR9EG

I'll just stick with the BR9EG per Honda

BR8EIX is what I have always used
