Default bad fuel millage on road bike build?

i helped build an old road bike for a friend it has 26x1x3/8 tires rear 3 gear with a 32 tooth sprocket sandwich hub 70 cc china motor from ebay ebay upgraded carb high compression head chambered exhuahst ngk plug and of course the loaded spring tensioned idler with gear and its also bolted into the frame also the studs on the china gas tank where removed and replaced with larger studs and they where brazed back in and the tank was coated with por15 to seal it dosent leak at all and no worries about it leaking

the problem is it burns thru gas like crazy a full tank lasts 65 miles at best and its just a stock half gallon tank any ideas tips?
