Mr Paul, Stig,
Guilty.
The best I can do, in many circumstances, online, or in the real world, is to present my opinion based on experience, to help others out.
It's up to them to take it with a grain of salt, or the forum in general to shoot it down in flames if incorrect.
Among the wisest things I have seen here on the Kymco Forum is the advisory that if a rider wishes a quicker, more powerful or capable scooter, with a few exceptions, it is best to upgrade to a larger model.
That being said, I've been quite impressed with young folks 'tuning' their mopeds for racing !
