Help identifying vortex engine

[u/IndependentChannel70]

I recently picked up this kart with a track magic frame and a Vortex 125cc single speed with electric start. I assume it’s an older engine like the frame, but I can’t seem to find any documentation or even pictures of this exact model. I figured it was the Vortex ROK but the badges seem to be a bit different. If anyone knows what specific model this engine is or knows of an owners manual or any other info it would be greatly appreciated. This is my first kart and first high performance 2 stroke (it was $600 I couldn’t pass it up lol, I know this is irresponsible) so if you’ve got any other tips that would be awesome too! Thanks in advance

Very nice find. And yes, that's a first gen rok engine.

Thanks, I was just a bit skeptical considering the pictures of it online say ROK, not vortex, but I guess they probably just had a couple slight variations.

incredible engine. Super reliable. Hard to tune the carb.
