Hello,
I don't know about the Oko Carb.
But i've riding with a Sheng wey carb fore the last three years on my TLR200.
No more throttle lag, and instant acceleration.
And when you would have told me this four years ago, i would't have believed it.
But what the heck, what do you have to loose.
These things costs almost nothing.
The least thing you can do is try.
And be surprised.
