Power Draw?
98 Road King with stock evo motor
I have A Kenwood HU with a B4 in the fairing pushing 4 Kappa 525.i and a RZ4-2000d in the bags pushing 4 Kappa 693.9i.
If I run my bike with the HU cranked up for an extended period my engine light comes on and my tail lights start to blink. It happens more frequently if I have not stored my bike with the battery tender hooked up.
I talked to some of the guys on here when I was putting this setup together and the general consciences was that I would be fine.
Any thoughts? Is my battery week or should I be looking into a better alternator?

This is a good point. Stator is a lower output but I would definitely try a bigger battery. The Yuasa I have has a 32 amp hr rating with 500cca. Depending on the stock Harley Battery can be in low to mid 20s for the reserve capacity. Also on the older bike being carb may not help with the lower idle point as well.

Not much really. Doesn't change the issue just didn't do any favors either. FI bikes have tad higher idle and smoother hence the lack of the potato potato sound at idle. An older bike like that first 2 things I would do is #1 battery. #2 check voltage drop on the ground wire to the motor. If the cable is corroded that will cause some issues as well.
