you have to understand that a motor like that
will only last a few hundred miles or even hours.
those are stage 7/10 scooters ~ full race
most guys go to stage 2 (pipe & vari/weights ,springs ) or stage 3 (cylinder ,carb or upjet & clutch)
for a daily rider you want to go max stage 3 and don't mess with the air box
for 10hp or more, porting &adjusting squish, thats how you get
but the scooter gets really finicky and eats parts
