Hey all, I'm a new vital member as of last week. I have browsed this forum a lot and have read a ton of the amazing bike builds on here. That being said, I have always wanted to do a full bike build. I am a senior physics major and for my senior research project this coming school year I will be building an electric KX 125. I have a lot of plans for this build, but would love some input from you guys as well as any advice you might have for the EV conversion. I plan to make this bike perform just like it did before I pulled the perfectly good running engine out of it. Here is the bike I picked up for $800 which I didn't think was too bad considering it ran.
Don't mind the 5 gallon bucket stand, working on getting one. Got it home on Sunday and began the teardown.
Supposedly the previous owner serviced it regularly. I guess cleaning the air filter wasn't part of his maintenance. Always a nice surprise to find a wasp nest in the airbox.

He also talked about the need to control the power output to make it controlled and rideable, what are your plans for controlling the power output?
Cool stuff, best of luck!
I haven't spec'd out a specific controller or throttle potentiometer that are used on most EV's but this is the route I am going. Have some ideas for connecting the throttle potentiometer to the current throttle set up.
Thanks!

Thus, you may have to make up a jackshaft / motor mount plates that incorporate mountings for the set up needed for a secondary sprocket and chain combination, to bring a sprocket to the center-point of where the original counter shaft sprocket was.
It's easy enough to make a neat little jig to key onto the flat sides on the KX's frame / subframe mount, or where ever, to then bring your 'solution' to for getting that final drive center line.
To reference the "AF Frankenstein" appellation from above : so many are just completely f**cked up by concentrating on the ancillaries, and ignoring just how massive an influence on suspension and handling the CS Center line is, in relation to the swingarm pivot, swingarm angle, and rear axle.
I've been involved with numerous Uni / College Engineering projects over the years, as an adviser / mentor /teacher. And, my goodness, I see the resources they have at their hands . It's a bit of a lessen for the very, very few that I've allowed to get into my workshop (which is nothing but a home garage), when they see what can be done, and done properly, with equipment that is so very basic compared to what they have access to. My fellow engineers and teachers, often, try very hard for me to break my rules about people nosing around in my very basic, minimalist set up. As they (well, most of them) want their students to have at least an idea /appreciation of what can be done at a 'hands on' level, and not just rely on Computation and Hi Tech equipment. Mind you, I do love being let loose in their facilities - I'm like a kid in a candy store.
