Can you tune an engine like this?

Good morning,

I want to motorize a go-kart with a few friends using this motor kit. Unfortunately, I'm afraid the engine might be a bit underpowered. Do you think it's possible to slap a 70 or even 85cc kit on it, or would it require welding, milling, etc.?

Here is the 50cc engine:

Unfortunately, I’m afraid the engine might be a bit too weak.

Yeah, that could be good.

You think it’s possible to get up to the ding nen 70 or even 85cc kit

I think it’s unlikely that the kit should fit exactly from the dimensions and I have doubts.

Then take a stronger motor, e.g. something like this:

or something thick, with which you would not have any performance problems:

Total

There would be about 50 inches, because the value exceeds 150.-.

In any case super important for air-cooled engines: during installation/construction it must be ensured that air flows around the engine. Air baffles or a fan may have to be installed.

You will hardly be able to increase the 50 cc motor. Are you buying a bigger one?
