1/3 scale model V10 engine 125cc. Megasquirt MS3 fuel injection with full sequential ignition using COPs. 3 stage dry sump oil system.Hydraulic triple plate clutch. 10 degree offset split journal crankshaft.
Most 125cc engines we see are single-cylinder units in entry-level motorbikes, but what you see here is no ordinary 125. It’s a hand-crafted V10, with sequential fuel injection, dry-sump lubrication and a triple-plate clutch, and yes, it runs. Keith5700 spent 2,500 hours by his own estimation to build a fully functioning V10 engine with a 125-cubic-centimeter displacement.
To make the feat even more impressive, he constructed everything in his home shop without the help of a computer-aided CNC milling machine.He fabricated the whole thing himself, which is crazy to think about.
It took nearly three years to build, but look at what he’s created,those intake headers and the rotors for the supercharger were hogged out of aluminum using a manual mill./Keith57000
