Front side of doo hickey after 130,000+ miles

But I did loose the spring which allowed enough slack on the balancing chain to let it eat into the cases
This also caused serious hooking of the balancer chain sprocket on the crankshaft, which with my anal approach to rebuilds makes this engine toast, and why I got a used engine to rebuild.
The mobil sythetic oil you are using-is it motorcycle specific or are you running a mobil 20-50 synthetic for automobiles?
