I am worried a bit about my LIKE with summer on it's way. The Aussie summer can be very hot and at least with a motorcycle the engine is exposed and not surrounded in plastic.
Don't think that you need to worry.
Remember these scoots are sold all over the globe...running on 3rd world fuels in hot climes.
Keep good oil in it, change frequently, don't sit and idle, take off your pants, don't do much WOTing. ( Note: all suggestions are just my habits.....no Kymco affiliation )
Good luck with that, down there.

I guess if you're really seeing an issue...you could remove that center panel just below seat front.
