need help with my 70cc speedfight 2 r-cup

hi, I owned a speed fight 2 r-cup, and I had put on a STAGE6 RACING 70CC, stage 6 STAGE6 PRO REPLICA CE EXHAUST CHROME, and a STAGE6 TM24 RACING CARB (with the right jetting). I was hoping getting everything in the same brand could save me the trouble, but the bike is not going anywhere at all, it lost all the torque. Therefore I had to put the 17.5 mm carb, and my old pipe back on to get it running again. I also try putting the new pipe on with my 17.5 mm carb(with the right jetting) but the old pipe got more torque and top speed,It seem to me that the more restrict the pipe is, the faster it go.... if you'll may ask I've try changing the roller weight on all setting already. plz someone help me out and let me know what should I do to get more torque and speed...

 

any restrictors in the new exhaust ?

 

as said already....you have removed the restrictors from the pro-replica pipe havent you ????

 

Yea I've removed the restrictions from the pro-replica pipe already, and I had tried with the restrictions on too, surprisingly the bike go alot batter with the restriction on...wtf

 

what the hell is wrong with you...youve now asked the exact same question 3 times in 2 different forums
