It may be that the charging system simply cannot provide enough juice for your gloves.
BMW touring rigs, they typically supply a few hundred Watts extra, for all the gizmos you could buy at the dealership. Same with Gold Wings.
Most sport bikes have the smallest/lightest alternators that can support their need in racing configuration. Not very many Watts excess available for use by the operator.
You should generally consider reducing the load somewhere, if you want to add to the demand.
The shop manual you can get here, should provide directions on troubleshooting the charging system.
From the Alternator, you should be getting > 52 VAC in between each pair (all three) of windings... 70+ is better.
After that goes through the rectifier and is turned into VDC, the voltage should be 14+ VDC, with the regulator limiting the upper end to ~14.4 VDC. You should see that at the battery terminals.
This is not a perfect answer to your real question, which is how much work can you take from the alternator before you start starving the battery? That has to be measured in Amperes, and you have to put your meter in series with the battery so you can see the current flow.
