I got tired of my butt getting pounded by my stingray seat. Looked around the shop for for what I had on hand fo fix the situation. The result worked out well. I mounted a hinged plate on the seat post with two tennis balls between them and remounted the seat. Very comfy ride over rough roads.
Main light runs off of a sla 4ah batt. Backup headlight (56 led) runs off self contained batt. Turn & brake light run off self contained batt. Am installing v-regulators to get rid of self contained batt. system is trickle charged off white wire with aux 110v charger(removed from emer-light).
Good looking machine. Congratulations. I had to laugh when I read about your tennis ball idea however. I have a Golden Retriever who loves to pop them. He chews done on them until they explode with a loud 'POP" I hope you don't have a blow out like that on a bumpy road.
