Reply #63 - 09/28/09 at 18:57:35 Well the keeper still had the tabs bent up so the screws just didn't back out. How's the cam journals look? did the cam sieze up shear off the pin and bolts? dam that's gotta be hard to do. tell us about the piston when you can.

Yeah... I noticed that about the tabs too. Not really sure HOW I managed to break those bolts.

I didn't really give the head a good inspection last night. By the time I wrapped everything up the sun was goin down, so I'll give everything the once over in the next couple of days.

Though I DID pop up the cylinder and have a look at the piston... no holes, nothing wrong with it that I could tell... looked like the pictures. Bore seemed to be fine too.

Im not believing the chaos in there. The HP required to shear those cam bolts? Im not able to visualize what happened. Im sure these thoughts will stop at a question mark instead of a statement, but, Ill try to walk thru it.

Running along & the tensioner lets go.. crud gets in gears & makes .. NO,,
Lets try this.

Running along & tensioner lets go.. Something rides the cam chain to the cam gear & gets pinched going over the top, driving down on the cam gear, busting the bolts?

IF the rosy picture I painted is what happened, IDK how the near journal will fare. That would be some serious "Crush". If thats what happened, the cam may be distorted some? Will cast even bend or does it just break?

I'll snap some pics of them in a little bit... but nothing visibly wrong to the naked eye. Or at least the untrained naked eye... The mystery continues...

You need 2 ( pick an object) that are straight, tall enough so the cam lobes dont hit anything, lay the cam journals on them & roll the cam back & forth, look for any wobble anywhere. Once you get the gear back on, that will show it clearly. If the gear wobbles when the cam rotates, its done..HEY, thats where to lay it, in the journals..duuuhhh, what was I thinking? Take the head cover & flip it over & set the cam in there & see how it acts.

From what I concluded, the camshaft quit turning because the cam gear bolts broke off,......... for what reason I'm not sure anybody knows yet.

Reply #73 - 10/01/09 at 14:17:30 The only way I can see it happening is something got between the gear & chain & the engine pulled it thru there, shoving the gear down & breaking the bolts. Thers no room for anything to go thru there..

Are the bolts std. jap bubblegum stuff or are they hardened tool steel bolts? On a critical application you would think the bolts would be something better than the soft stuff they use elsewhere.

I saw lots of damage to the sprockets in the pics -- sprockets ARE case hardened steel so what did the damage to them? Whatever it was had to be HARD as well.

Where was the little roller pin that goes thru the sprocket into the cam flange?

Had someone worked on this bike before?

==============

My bet is "repair error" and somebody had worked on it before.

Overtorque the two soft bolts and they yeild & stretch -- and then snap in use releasing the little hardened roller pin to do the damage as seen in the pics.
