thanks in advance! hope can get the proper help, to solve this mistery! lol
The QinQi (轻骑)16T sprocket (链轮) you are looking for is easily available here in the mainland... If you cannot find a replacement for yours then PM me and I can help you obtain one or two... sorry can't help you locate a replacement in Portugal though. The lower pictured sprocket is for a QinQi 125-2 and is a 13T.

Contact them to find the local seller / suitable sprocket (w/ measurements ): http://www.jtsprockets.com/contact/
thanks for ideas, i will to find out the best way to solve this.
for now i trying to told my local seller, that 16t exists, because on his catallog they see exact same thing on http://www.jtsprockets.com/catalogue/sprocket/JTF410 , that only have (max) 15t.
But i showed to them the upper picture, that proves the existence of 16t...
I now have to wait.
Sorry poor english...
Thats a bit strange, the exact same bike, Qingqi sport 125 / Sinnis Stealth 125, has different front sprocket mounts... i dont get it... lol
16T [JTF417/JTF425/JTF1263] is similar pattern BUT the thickness …
That pattern is on Korean made suzi (& clone) in most case. Why it's on there (prototype… ??? ) will remains a myth until Qingqi told u.
Who knows... maybe it has to be about different gearbox?
Here in portugal SM models came with more common sprocket, and it has different gears.
What im 100% sure, is that i feel to need one more extra gear, so plus 1 teeth are wellcome. Lol
Yesterday i took a ride with another bike like mine but with no mods, and the gains is huge! It feels like i have about 2/3 more horsepower! Maybe 15/16 in total.
My carb is now with 110 main jet, and my mechanic adviced me to put it one 115. Im on stock 125cc barrel. Isnt that too much?
