Air box oddity Jonway 50cc

[rsfluffy]

Examining my new scoot, I found that the air box intake was taped off, reducing the air flow by 1/2...I removed the tape and the performance tanked.

I contacted the previous owner and he didn't tape it off. So either the dealer did that or the factory. Anyone else seen this? Seems an odd way to control the air/fuel mixture!

Seems to me that a re-jet is in order. am I wrong?

Thanx
