Hello all, first time poster.

Well I'm new to cycling and just bought a 2009 fuji roubaix with 105 front derailer and ultegra rear. I've found that it is somewhat difficult to switch to the big front ring when in little rear gears and some times the chain just comes off completely. I'm wondering if I'm doing something wrong or if there's an adjustment I can make to correct this? Also when I push the black lever on the left handle it makes a loud click, not a subtle one like the right side. Is this normal? Thanks in advance for the help,
