Hello,
First the easy possible solution, the fork oil. At least on my a10gf, too little oil made the front dive to the ground while braking and the front suspension was very "wobbly" while driving. So is there enough in there and is it thick enough? 0,21 to 0.22 litre is fine, and maybe you should try going up to sae 30 or even more, you are in a quite hot climate, and normal sae 10 or 20 fork oil may be very thin.
Just some ideas to start with.
Regards
Erling
