Kymco Vitality 4t motor swap

[Valhalla02]

I've got a 2007 kymco Vitality 4t.
Originally I was planning on just doing a BBK but since most parts I can find are for the agility and GY6(don't know if they are compatible), I was wondering if a larger motor by kymco (ie a 150)
Anyone know if there's a bigger motor that would fit?
Otherwise what should I look for to know if parts are compatible?

Good luck getting a response.

I posted the same question...still waiting.
