Help Request: Rough Idle, low mpg

[Bigthangs65]

Cracked Cylinder Head. If you are losing coolant and loss of power bad MPG sounds like typical cracked head issues.

Ok, well...the Bars HG-1 is still holding just fine, Im at 163k miles now. Ive done multiple long distance trips without any issues whatsoever up to 115F ambient. Just came back from a 2000+ mile trip from vegas to black hawk, Co....no issues whatsoever. Fluid levels holding, MPG holding.
