Lost all my radiator water today.

Today we were out riding, and my bike started to act funny. Over-revving on its on, detonating and the like. I wasnt sure why it was doing this. I had went to the BR8EG Plug to try it out since my manual says that is the one I should use, so I thought maybe it was that. Well, I decided to check my water for some reason, and noticed just steam coming out of it. I didnt have any water for miles, so I found a bottle and got some water off the top of the creek. It wasnt real dirty or anything, so I figured it would be ok. When I started to pour it in I noticed water pouring out near my leg. It was the drain plug on my water pump housing. DAMN, it had fell out somehow and all my water was gone. WE had no screw and we were a long way from the truck. SO we found a stick and jammed it in the hole, and filled it up. Shortly after it cooled off and ran fine afterwards, mostly. It did however require that I lean up the air screw from then on out for it to run without bogging and it really didnt run as good as it had been, but close. I am going to open it up to make sure I didnt hurt anything. This thing was really hot, and it even started to boil over at first, then it cooled off and seemed to be ok. The question is, could this have damaged my bike? Rings? Piston? Head? Anyone else run out of water before?

I pulled the top end apart right after I wrote that post. I do have something that looks like sieze on the intake side. The exhaust side looks fine. There is no crankpin rod bearing play at all (very nice) Very little side to side and no up and down. There was what I think might have been a tiny almost not for sure type movement on the wristpin rod bearing. It was so little that I wasnt sure it was actually moving. I have some pics of the piston. There was one time while I was riding it, and I was sitting there idling (before we found it had no water) and it just suddenly died. Not a sputter then die, but a sudden STOP. I didnt think to much about it, but looking back I bet it was right then that it seized. The cylinder is fine. No marks and still has plenty of crosshatch (recent topend rebuild. Less than 20 Hours). I am thinking that if I mic the piston, and it is still inspec, and the ring gap is as well I will reuse it all. I will replace the top rod bearing just to be safe. One thing though. The piston, while on the wristpin, has alot of side to side. NOT rocking side to side, but sliding along the wristpin from clip to clip. I do not know if that is normal, but I noticed it in other bikes I have worked on. Also, the head gasket had blown as well, that might have been the slight bog we were getting. It wasnt a real bad blow, but examining the gasket, you can see it. Anyway, here is a link to view the pics. Dial-up beware, might be large.
Just a side note:
The inside of the piston was spotless. not even a hint of black. Lean?
The bottom end when I rotate the crank, is very effectivly oiled. I was very pleased with that.

SO what you are saying is that the little bit of intake scuffing isnt real bad, and most likely things will be fine? I am going to mic the piston, and check ring end gap. I dont have a tool to check the cylinder for out of round. If everything is within spec, I am going to just put it back together. With new gaskets of course. Wish me luck.!!

I plan to with my little brother and some friends. I am to the understanding we will have to richen things up a bit.. but it should be ok..Why do you ask..?

Good plan.. That is probably what I will do anyway even if I do get some winter SNOW riding in. Since I was here last, I have taken the rings off the piston, and looked at them more closly. The bottom ring is missing the little tab that the others have. It looks like it has been broken off. It is in direct line with the scuff on the piston. I think the piston is ok though. What do I check for to make sure it is within specs? There are no cracks, no chips, or anything of major visual concern. DoI mic it to see what it mics?

Where can you find it all for that price? Wiseco wants well over 118, and the piston pin isnt included. Then I need a top bearing, and gaskets..LOL If you do really know a place for sure where I can get those things cheaper do tell. Would love to save what ever I can..
Bleeds..

LOL I cant find it. I find other that are almost the right one. I guess someone will have to email me the number. Oh well.. Probably not the one I need anyway. I need one that is 50mm. Maybe if I post my email someone will hook me up....LOL oh well wishful thinking..
