The breakdown of the engine code is as follows:
- K – K-series
- 53 – Approximate daisplacement (cu·in)
- 2 – Twin cylinders
- Suffix (engine is available with the following options):
S – Electric starter;

I think it’s awesome place to gather info . Need some parts numbers like camshaft or oil filter. Can’t find out nothing bout end play on crankshaft or assembly of piston in order to provide end play,seems it does matter if rods are one way compared to another. Thanks but can you provide me with parts numbers.
