Good God, I hope not! I will know more when I get the chain off tonight. I still have to remove the lower cover. I wonder where the rest of the chain ended up and in what condition.
I am rebuilding the top end of my '83 Harley. The rear exhaust valve guide came out of the head and stuck to the valve stem. About half of the guide then was ground up into little pieces while it was pounded into the head. I have had to take apart the rest of the engine so I could rid it of the little bits of metal.
I'm hoping I won't have to do anything of this sort for this engine. While I have low oil pressure (less then .25 bar) when hot, I don't relish doing a bottom end yet.
BTW. I have always been very careful to keep the oil pressure to at least .75 bar when at idle. At RPMs above 800, the pressure is always above 1 bar and at speed it is 2.75-3 bar.
