Just thought I'd give an update and go ahead and send this thread to its grave. I took a break from the bike and worked on some of my other projects. I ordered a camera to go down the spark plug hole, and this is what I saw.



The bike has 1,490 miles so I don't even know how they managed to do this. So I'm gonna do some research on rebuilding it before I start tearing it apart, or I might just sell it as is, I've got too many projects right now. I'd like to thank everyone who helped me, I learned so much.

You may just need a piston and a hone of the cylinder, as long as the head is ok.  It is worth a look to pull the head and see what it all looks like in the light of day.

So few miles and a hole?
That's unheard of..
I'm guessing it didn't have much of a rhythm when it was spinning over and rolling it in gear wouldn't be held back by compression, but who knows what resistance is in that screwed up mess?

Eegore was gonna tell us about a problem and solution.

I had discounted the possibility of a hole, so I didn't mention blowing in the plug hole and seeing if it came out the oil fill.


I wonder how much suction it's creating on intake. Probably around zero.

Too far away from KY for me to be of any kind of help in person.

It is not that difficult of a job - and it would help to know why it did this, and what kind of shape the cam/rocker/valves are in.

It is a tough thing to decide what to do when they are in this shape.  If you want the bike it can be fixed up - but you could also sell it and look for one that doesn't need this much work.  If you want to hop one up with a Wiseco......this is the perfect bike for the project.
