Carb stuff, still, again, EDITED

     Should the voltage at the battery be 14.5 at idle? I ran the fault finding chart from electrex and at idle I was at 13.8 and at 2,500 rpm & 5,000 rpm I was at 14.3... According to the chart, my charging system is working fine... After I cleaned all of the connections I checked it and got the same numbers...should I be worried?

13.5-13.8 at idle

when you bleed the cooling system, do it on the center stand and have someone push down on the back of the bike & block the engine up so the ft wheel is off the ground (per the Yamaha TSB)

I've always observed 14 - 14.7 V @ idle.  Both with the original stator (while it was working) and with the new one from Rick's.  I also changed to a new (but original type) R/R.  The volts immediately after starting are around 13.8 but within a few seconds are back up to 14+ @ idle.  I keep a Battery Tender Jr. connected whenever I'm not riding or working on it so that may be why I have a higher reading.  Voltage readings between 13.5 & 14.9 are OK.

When my stator fried, it would never charge above 13.3 volts at any RPM.  The higher the engine speed, the lower the voltage.  I don't think you have anything to worry about, Sable.  At least no more than the rest of us who wonder when the next stator will fail.
