fit big bore 180cc on agility city 150cc

[Rorut]

I have an Agility City 150cc I bought used. The model does not seem to be listed here.
Here in my country the agility city comes in 50cc and 150cc.
Trying to find information about my engine and if a Naraku 180cc kit would be a bolt on fit?
I dont want to split the engine and opening the crank case.
Anyone that know snything about my engine and tuning it?
Thanks!!

Ultimately, it's really hard to know if it'll fit the crank case opening or not. It seems to vary from model to model and I understand not wanting to remove the top end to find out - I wouldn't want to either.

Anybody on this forum fitted a 180 kit?
