have a 78cb750f.  read somewhere that stock sprockets are 14/43.  wanted a little less buzz
at higher speeds so went to a 15t front, now the spocket cover won't go on ( :P ), but that's ok. 
no idea how you squeezed a 17t in there, sure an 18t will fit?

What year is your bike?  77/78Fs absolutely have a 14/43 gearing setup factory. As well as a completely different chain.  (630 vs. 530)

We need to know what your front and rear gears are currently. As well as what your goal is.  Lower highway RPM?
