You DO KNOW that when you overhaul the newer L series Honda engines you need to replace the following bolts with new ones
main bearing caps
con rod caps
and the machining tolerances of the crank to bearing shell is very tiny in this engine, Machinists are not equipped with such tools in Pakistan. And the cylinder honing is done like the H22 - it leaves a strange looking matt finish on the cylinders.
Its a little easier to firstly check the compression and oil pressure then determine what failed and repair/replace accordingly. Its a toy of an engine and does not tolerate hammer/chisel tools
