Hey folks. Thanks in advance for any insight. I've had this tach on my bike ('77 cb550f) since I've owned it (a couple years now). Rebuilding it has been on my long list of things to work on... because it won't rev past 4k. I noticed while looking around that folks are selling tachometers for my year/model that redline closer to 10k.
Just want to make sure I have the right tach before I tackle taking it all apart...

Thanks again!
