Motor seizure!

[fallingpines305]

OK, there I was taking my Hawk onto the highway for the first time in a long time after a 20 mile run on country back roads, cruising along at 70 , then loosing some power, down to 60, then my rear tire locked up, pulled the clutch instantly, engine stopped, coasted off the highway, took a deep breath, checked to be sure I had oil (I did), waited a couple of minutes, started it back up, idled OK, proceeded slowly to the next exit and home.

Now, as a precaution, I dumped the oil while still hot and didn't see anything alarming. put in fresh 30 weight, started again and it sounded and ran fine.

So, should I be searching for some 1st oversize pistons and going for a bore? Also, what was the trick I heard where oil holes were added to the back of the cylinder to better lubricate the piston skirts?

Is your timing OK? It didn't lean out did it? Just thinkin' Kustommusic

Same thing happend to me last autumn. The advanced timing was way out... Strangely the engine sounds OK and runs fine, so I decided to run it this summer without any rebuild. Tough machines, they are.
