Carb Diaphragm (Throttle Slide Piston) :: Hyosung GT125R GV250 GT250R GV125


After many years of hard use; old worn throttle slide pistons (aka. diaphragm) should be considered to be replaced during a rebuild/overhaul session to maintain optimal carb performance.
Damaged & sticky or torn-up slides will cause all kinds of weird behavior from surging, incorrect fuel metering, boggyness while riding etc…

A good diaphragm helps to regulate the fuel in the mixture , thus allowing most the optimal carb performance as intended.

    If you’re looking to improve your 6-7k rpm I would highly recommend this along with the needle that can also be found on this site. I had boggy type issues and after installing this and the needle it’s gone completely, very easy to install 10/10, great help from Marcel too answering all my questions when needed, top guy!
