Pics first then comments.  Get pics of the piston and the cylinder walls.  Also pics of the valve side of the head so we can see the valves.  Ohh and a pic of whatever was inside, things dont just "fall" into the cylinder.

If piston met valve, at least a valve or two are bent and a valve guide or 2 could be toast.
Heads most likely not.
Pics is good.

Like I said, I don't know how to post pics. If someone would kindly tell me, I have them to post.

Ya know, as soon as I got to the link, I remembered that you have to upload them elsewhere and post the link. [bang]

So, here are the pics.

Man I have no idea wtf that thing is lol.  OK, so I cannot see the cylinder walls in any of those pics.  The intake valve looks like it took a good smack.  To be on the safe side and since you have one off maybe take a look into some HC pistons and maybe have a shop check out the cylinder and the head..  ca-cycleworks has some nice pistons for a good price.  I would not run it like that but thats just me. 

I would go ahead and replace the pistons and have both cylinders checked along with the head that took the beating while I had it all disassembled.

You're right, you can't see the cylinder walls because I didn't take a picture of them. (sorry) They are however, baby butt smooth. No scratches or nothing! [thumbsup]

I would love to replace the cylinders since it's apart but since I'm not working any more, that would be difficult. (mortgage...food.......pistons? tuff call)

What do you think, can I smooth down the narf spots and still be OK? I spoke with my father-in-law who was a bike mechanic to the 'Stars' for years before moving to the midwest and he thinks I should be able to do it without damaging anything else.

At this point how much more harm can be done? OK, I suppose if I really hose it up I can, for sure, tank the valves but what am I going to do?

I think I'll try it while waiting for the dealer to call me back tomorrow to let me know what they think. I know what you're thinking, they'll tell me to replace them, but, I'm pretty good friends with a couple of the guys and they'll tell me what I really need to do.

I mean in all honesty if you are trying to do it on a budget than careful cleaning of all the affected surfaces may just get you by.  Do your best to remove all the embedded fragments and you might be fine.  Do try to figure out what that mangled piece of crap is that got in there though lol.  It is bugging me.

Here's what I got...

The intake valve did get ever so slightly tweaked so that needs to be replaced. ($134) and also the valve guide needs to be replaced ($50 for part $50 to do it). All told it's going to be about $250 to get it fixed. Now I realize that I am apparently very lucky as to how all this happened and am thankful for it.

I really want to thank all of you for helping me out with this. You gave me the push to rip it apart until I found what was going on even though I've never torn apart a motor before.  [clap]

Now I just have to aquire the funds to get it done. Since I'm not working, my budget is a bit tight. My wonderful wife (whom I love very much  :-*) is also adjusting our budget to make it happen. She says she doesn't want me to be crabby all summer. How cool is that?

It will be a couple of weeks to have the valve guide repaired so when that happens and I get it all back together, I will let you know what it goes.

Again, thank you for your help!

And, I or anyone else I've shown, cannot figure out what that part is. I even sent a photo to the dealer and they have no idea either.
