i got a fcr 33 carb and im having some problems with it. i sent it with my motor to my motor builder and he checked it and jetted it. i just got it all back together tonight we went to start the bike and it doesn't seem like its getting any fuel. we were thinking about putting the stock one back on but i don't know how it will effect the motor with a big bore kit, ported, and upgraded cam. it also has an hmf slip on with a prodesign air filter(no lid) for any jetting suggestions.
