Got a Honda F22 to pull apart shortly, but the last rebuild I did (AMC 4.0) was due to this:

Thermostat failed shut in gridlock traffic, blewup the rad and seized the 2nd piston.

Fuel pump overpressure?  That could cause leaky injectors and cause the crankshaft to crack under the extra torque.  That would also cause the gas in the oil.   Also would cause the overheating, which would blow the radiator and cause the pistons to seize up and fry.  Clogged fuel reg, would also clog the return or admission line and cause over pressure.  Sediment in your tank possibly?

After a long search i've found a donor scheibendynamo ( the one on the left). An other step closer of getting my motorcycle running. :)
