Hi, 
Has anyone ever tried the 225 CC kit on GG TXT 125 2011? 
I would like to add some more power and torque to my 125 GG.  
Does anyone know whether this kit is trustworthy? 
I used to have a formal exprience athena kit on a YZ 125 and it requerd me to change the engine piston for about once a month. 
Thank you for you attention. kit
