bronco,
thanks for the reply. I will take the head in and have my dealer look it over and replace the valves if the head is good.
I am not entirely sure its a piece of bearing but the piece I found was a thin polished tube about 1mm in diameter and about half an inch long. If I could get the pic up I would show it to you. the debris is just gritty stuff in the oil that seems like it maybe from somewhere in the bowels of my bike.
thanks for the help

Is there side play with the rod? Does it appear to be bent?
With that kind of crud in the case.. No doubt ,, I would split the case to clean and inspect.. If there is more damage,, you'll find it.
The piece as you describe it,, sure sounds like a roller bearing...
trying to come up with another source what that piece of debris. nothing is coming to mind.. Perhaps Burned or Nobel will have an idea. But really, it's all just guessing,, the motor needs to come all the way apart IMHO, inspected, repaired ,,,before you consider putting it back together.

I just stopped home to get some supplies.
I agree, I have to get her cleaned up and look at all the pieces in the bottom for damage.
I am going to go ahead and order the piston, rings, flywheel puller, gaskets and a manual today so I can keep working at this.
could the debris have come from the chain guide? the guides are grooved a bit from that partially broken chain. actually that just poped in my head and explains the grit, but not the roller. still gotta find where it was supposed to be and look for others.
I am still kind puzzeled on spliting the cases, it looks like its one case with side covers only, are the two halves connected internally?

Could that piece be a cam chain roller? Awhile back someone else had a failure and after tear down found scars inside the oil pump housing. Things like that are the reason for a full tear down. Just be glad it's a single.

Yes two case halfs... Split down the center,, standard bike stuff. Lots of pieces and parts come off, before you split the case........ Take lots of pictures at every step.. mark/bag every part and fastener. You will alos need a tube of sealant for the case seal.. when it's time to go back togeather. That was a bit difficult to find where I'm at. So start looking now,,order it from a dealer if needed.

OK,, so the grit you keep refering to is not metal.. but black plastic??? if so,,, yes that sound to be the chain guide.

I thought that too but close look at the chain says no, unfortunetly.

I figured he meant the stakes that hold the plates of the chain, right?

The chain pin or roller itself.... Was there any missing from the cam chain? I'm thinking the size are not right for what you said,.... but I'd have to go look to be sure..

How many miles do you have on the bike? It seems to me strange to have a cam chain failure if all else is OK. Any chance you over tensioned the cam chain with the MCCT? Could a cam have siezed?
Posted 01 January 2005 - 07:56 PM
While were on this subject. Is there a recommended overhauler a person could send a motor to? Just for future reference!
Posted 01 January 2005 - 08:53 PM
No one asked. With the head off and the chain out, can you rotate the motor by hand , or is it still locked? Just curious.

As soon as I loosened the cams it was free to rotate.

UPDATE:
cams look okay, head where they sit doesn't. So I will be replacing the head. The connecting rod does seem to have a little side play, very little but it does. I can look in and see the crank roller bearings, they look okay but I haven't gottten it far enough apart to be sure. Still unsure where the bearing piece came from.
I will probably end up replacing the:
head
valves, springs etc
cam chain
piston rod bearings on rod (both ends)
gaskets
looks like about 1100 bucks at ron ayers so far

new question
does the part listed as head assembly mean the head or the head with other parts as well? such as valves etc...

Are there valve guides in the head that would be listed as separate parts?
