Help for newcomer with Yesscom kits

[A Monell]

I'm fairly new on this forum and this is my first post. I purchased a 36 V 500 W E – bike kit last spring from yesscomusa online. I fly radio control models and am well versed in the safety issues and sources for lithium polymer batteries. I currently run on four 5S 5000 MW batteries for 10 KW. It has worked well and now I have decided to upgrade to a full suspension bike and have purchased an 800 W kit for a bit more speed. I am looking for hints and tips about what to fix and/or upgrade.

#1 Obviously the motor wire connectors need to be done with something better. I have plenty 3.5 mm gold bullets. Are these sufficient. If not what millimeter?
#2 I have opened the controller and will spray with corrosion X, plus use ample heatsink paste when it goes back together. Anything else while I have it open? I saw some reference to modifying the shunt but wasn't sure what this was for.
#3 The motor wires look extremely thin but I don't think anything thicker will fit through the axle.
Is it really of any advantage to redo the wires from where they exit the axle to the controller?
#4 There are two bolt holes above the axle for a protective cage by the derailer and I have made two 1/8 inch stainless torque plates to bolt through these holes. I will also modify the wire cage to protect the motor wires as they exit the axle.
#5 Anything I've missed or other recommendations?
Thanks, Alex

If you are running an 800w controller, you shouldn't need to upgrade the wires. Generally upgrading phase wires is for the folks running in the 3000w or more category. At 800w, they shouldn't be gettin hot. But do go to good connectors, since a cheapo connector can heat up and melt the housing. Quality RC 3.5 mm bullets should be fine for your 800w, even if you run 48v and have closer to 1200w. Just don't use cheap trailer/ automotive bullets like some kits ( like WE) used to come with. Fine for taillights, but not for motors.
