Racing Plugs

Good Afternoon,

Can anybody tell me or give advice on what type of spark plugs to purchase for bantam 125 & 175 aircooled race engines and if they would be available to purchase at motorcycle dealers.

Many Thanks


Eddie

Perhaps a question for Peter or Alan, could make a comment on. !

I use under instruction B10EV or EGV although I have been using before this B9EV or EGV. IN MY AIR COOLED MOTOR

It would be good if other's could comment on this or where you get a chart from on plug range,

I am not sure what the letters mean, somthing to do with nose type or materials made from,
perhaps the above would please make an information comment for us all on this topic. just for those like me "who don't know" or "can not remeber".

regards Derek

All you ever need to know regards NGK plug codes is on this link

i use on the air cooled a b9egvr (iridium) as it is a resistor plug and is required to work with HPI ignitions, and the same plug but a 10 for the water cooled.

Thanks for the info, will see if they stock them down the local bike shop and give them a try.

Hi I run a 10 plug in my motors if I run a 9 it gets too hot
start with a 10 then go down to a 9
so is the bike going tobe out this year ???

Hi Robbie,

Thanks for the plug info, who knows as it is still being built and started doing it when we did the marshalling course at mallory park quite a few years ago!. May try and sprint the others this year if we can get them running right though!
