Welcome back
.
Sorry to hear it sounds like you've been through a lot. Hope things are getting better for you :wink: .
So does it start with the new battery? Are the connections and the ground clean and tight? Both my Zongs had somewhat anemic starters, and one sometimes spun kinda slowly even with a charged battery :? .
I'm not familiar with transmission issues in this model, sounds like some generic bad luck there.
Maybe you have too much fluid in the brake? Maybe the pads are dragging causing friction and heat buildup and expansion of the fluid. This us a semi-common issue in the Hondoid rear brakes and may be a factor in your front brake.
