Hi Spud,
I want to shift the air box for a high flow air filter but not sure if shifting stock for aftermarket will affect the iddle or need to rejet. Any experience with this issue?
Also, does the tw200 swing arm is similar to zongshen's swingarm? I need the plastic that protect the swing arm from the chain. I think is called clip at least Vento sells it under this name. I checked out all your threads but none is related to these issues (or probably I missed the right one).

Thanks
