    250r cool head ??

    I was interested in purchasing a cool head for my 85 250r , but after looking into them i got a bit confused.. A bunch of these are on ebay listed differently by cc's ?? Not sure what difference this makes .. My 85 is mostly stock other than a fmf pipe and silencer , running on 93 octane pump gas and i'm not sure if it's a stock bore beings i havent had the motor apart.. Can someone give me a little info on what ''cc" i should be looking for .. Also if anyone has any reviems on this product it would be great .... Thanks in advance!
    MY BABY RIGHT HERE !!! LOL

    The lower the cc of the dome the higher the cylinder pressure (race fuel). Duncan racing sells heads in 15 - 22 cc's call them and they will work with you to figure out what dome is best for your bike and riding style.
