I have posted a few times with no avail..... My xb600 is acting weird... Its upgraded to 60V and with the pack at 63V it starts to die out on me. The pack reads 63V but under load it drops to under 48V, but when I let off the throttle it jumps back to 63V!!!! I dont know where I need to be looking!!! I have all the bike covers off with access to the controller and all wiring. I can not see anything wrong with any components of the controller. I have the rear wheel off now, but I cant seem to figure out how to open up the rear hub motor!!!!
Any help or suggestions PLEASE !?!?!?!?!?!?!?!?!?
