has any G5 owner put C5 drive sprocket on their bike.
David -
many B5 and G5 riders with the 19" rear wheels have "upsized" their drive sprockets from 17T to 18T (the C5 comes with the latter), when mounting an o-ring or x-ring chain on their bikes, ostensibly so the chain will clear engine casing protrusions - although I've heard that this
isn't necessary, and also that it
is necessary... so YMMV. But the answer to part of your question, anyway, is yes...
