what is the best plug to use on a 87 250r with a decent built engine on 1005 octain??
thanks all!!Text

 

sure is some fancy fuel your running. I imagine you mean 105. You can run a B8ES and you'll be fine

 

LoL Must be a decent engine. I bet that fuel is expensive. Just messing with you man.

 

IMO b8es suck there just to easy to foul... You should use BR8ES, and if you want a race plug go with BR8EGV. Also gap it at .22 because the 250R's eletrical system is weak so this will make the spark beter and it it will reduse any spuddering

 

thanks guys yea 105 not 1005 da thanks guys
