Hi Wrench, welcome to the forum.
Sounds are tough to diagnose without hearing them. You didn't say how many miles are on the bike, but chances are your noise isn't too serious. GL12s make some gear-whine noise.
You might want to take the bike to a local shop that works on older machines...or there are forum members in your area that might be able to give the bike a listen.
Why ain't we ridin'?
