I thought I mentioned it, or used some other phrase earlier, to describe a condition that just didn't seem right to me. I thought I posted pics.
When I turn it over by hand, the pressure from the valve springs cause the cams to abruptly snap to closed position after over-center and the cam chains seem appear to loosen up and on the intake cam they look like they lift off the cam sprocket a bit. I think one of the pics I posted showed this, but maybe not, it's been a couple months now.
So now I am beginning to think that this is the problem with this bike. It would explain the other piston I have sitting in a crate with valve marks in it. Remember, it came with 2-3 boxes of extra parts.
But the tensioner appears to be new so I am wondering why it would be happening?
What else could it be?
Stretched cam chain? Wrong cam chain? Bad tensioner?
Before I had it running this past weekend, I made sure that the tensioner was as tight as it would get, and it ran pretty good and made good power. And that is what is confusing me.
I should probably start a new thread, since it is no longer a no-start situation.
I bought a used upper cam chain off eBay and am going to go and measure it tonight. I have suspected this since the beginning but never measured the chain thats in it because I didn't want to tear it down that far. Now that I have another I will measure it and see if it is in spec.
If it is, I may have to swap it, then measure the one in it.
