[QUOTE="Mihylo33, post: 171062, member: 408"] That looks to be a sx jug. They shave the reed box just a fraction to get that low end grunt. They opened up the lower ports to allow more fuel into the lower end (notice the gradual angle to create a funnel effect) and the upper port vas been bored larger with a sharper edge to allow more oxygen rich fuel (which is lighter) to turbulate and atomize quicker... Merely speculation though as I am not a machinist..... Just a guy that likes dirt bike....... I really fucking love dirtbikes:hug: [/QUOTE]
