I am looking at ordering a russell seat for my new to me wee strom. I have a 2007 with the 375 watt alternator I believe. The bike has suzuki heated grips on it now and a powerlet connector that may get used for my iphone. Will i have enough juice to run the heated seat? Anyone doing this now? I am not forseeing the addition of any other electronic except maybe a gps later or some driving lights. Am I asking too much of this bike for charging?
