I have a Brand new Pro Design Cool Head for sale. I was going to use this for my bike but now I need a new top end. So, I need the money for this issue. It comes with the head and orings nuts and washers. The domes can be purchased thru Pro Design I never did get the dome because I was going to have the cylinder ported. I later found out that this will only be good for cooling pretty much a stock bike. So, don't buy this if your bike is race ported. These heads alone cost over $200.00. I want 100.00 plus shipping. Just Pm me and let me know. I'm checking into paypal for payments.
