New Prototype Engine: ZR28R Rebuild

The parts I've been waiting for has finally arrived and it's time to rebuild the ZR28R! This video is going to show the whole rebuild process (sped ups only by 2x) so it's going to be fairly long and not very eventful.
Feel free to skip this video if you aren't into engine building and such.

What small block it that? Ive never seen a internal oil pump on a clone based engine☝️

[@JSRacing-Kartsmith]

It's actually an amalgamation of parts from various different engines. The case cover with the pump and filter is a custom made part and its no available for purchase at the moment. It works very well though filtering out all the nasties from the engine oil. It allows the engine oil the last much longer and has much more effective lubrication for the crank shaft / connecting rod.
