Don't be fooled into thinking saw based jugs are weak up top. They aren't. My Phantom has zero issues screaming itself to 9k+ on just a port matched intake and a stock carb. 15cc of displacement with all if it being bore size is nothing to sneeze at.Im a high end type fella I can alwas add a few low end mods to balance the difference. Not bashing my CG their a throw away motor. In 3 years been throgh 3 motors. Due to manufacturing defects, and striped magnetos and jugs. Plus the china alum. Is like pot metal. Super soft.I need something I can gas but still retain durability. SO Adding all the advice on top of my gut feeling. IM GOING WITH RELLI.
thnx guys.
Put a proper pipe and carb on one with said port matched intake and they do nothing but slip clutches. The person who started the Phantom Facebook group found that out the hard way lol. He told me he has no doubt his bike could hit 55 to 60 if he was brave/foolish enough to do it.
The intake port matching is critical to really unlocking the potential of the motor too. They really narrowed it down at the flange in an attempt to regulate rpm and power (I assume at least).
