Hey guys I have a 4 mill stroker with the t-rex cylinder head and pistons , that i just bought now here is my thing the guy i bought it from says he wants to keep the head and he will drop the price of the bike by like 2800.00 bucks honestly 600 cc is alittle much for me , so i would rather run a head. I'm just not sure if i can ? so any info that could be provided would be very helpful .
