just rebuilt my 05 honda 450r and it's got maybe a tank of gas ran through it, i noticed my radiator was low on fluid filled it back up and rode a little more and then when i came back checked everything again, but this time the oil was just a lilttle milky, everything is new, do you think i need to get my head resurfaced? the guy i got it from blew it up so i firgured it proably got hot might have warped it a bit what you guys think?

you might gain 1 or 2 more points i would be using at least 104 octane with even 12.0:1 comp im running 13.6:1 and i run 112 leaded but its my opinion on the situation lots o people on here are misinformed i think
