deviant said:Got it back on the road. It runs better, but still runs rough and has a tendency to stall in idle. I've got black soot on the plugs which now has me thinking weak spark. The right side is slightly better than the left. The primary resistance checks out at 4.3 ohms, but I can't get a reading on secondary resistance. I'm going to order coils and plug wires, and hopefully this is the last step.
I took a quickie gander at the suspect rocker arm, and it looks like the thread hole is slightly oval. Considering it's happened twice to the same arm, this has to be my culprit. I don't know if the ovaling could have come after the tappet popped out, or if it caused it to come out in the first place. It also is happening on the cylinder that didn't fire when I bought the bike. Could this all be signs of a common issue that starts with the rocker arm?crazypj said:Threads are probably buggered up in the rocker arm.
The bottom threads and top of valve are probably damaged as well, I've seen rockers that have run directly onto valve tip, real lucky the cotters didn't jump out and drop valve as well
How tight are you getting locknut?
Too tight is as bad as too loose
Alternated tappets to see what I've got. Everything seems precision. It just occurred to me that I could have had a bent tappet, not a bent rocker. At least that makes some sense. Of course, I am open to the possibility that I over torqued that tappet. It doesn't show in the rocker threads, though. Regardless, new rockers are being ordered.xb33bsa said:hows the tappet fit in the threads ?,it is supposed to be a precision fit without any wobble
you cant tell just looking at it unless it is real obvious
looks like it is time for new ones anyway :'(
how are the lobes ? :-[
deviant said:Again, no internal damage. It's hard to be stupid and lucky at the same time, but somehow I've been successful at it so far.
