I ordered some molly studs from APE for the turbo bike. These should keep the head on straight. They are much thicker than the ones I have in there.
That's what I get for cheap'n out in the fastener department.
In the mean time I am adding more oil cooler to it to try to keep the temps down. I am also looking into converting it to E85. I hear it tunes easier and runs 15% cooler.
