I'M TAKING MY BIKE TO GT.THUNDER TO HAVE A 440 KIT INSTALLLED TOMORROW. WHICH CARB IS BETTER FOR IT? FCR,39MM OR THE 41MM? HOW DO THEY COMPARE TO THE ELDEBROCK 39MM QUICKSILVER?

 

I have a 39mm FCR and it is great except when it is very cold (no choke). I havn't heard much about the QUICKSILVER except hearsay and people either love it or hate it there is no inbetween.
Also when installing a 440 kit make sure that the shop uses a jig to keep the cylinder round.
