Hi everyone
I just joined the forum today after checking out some of the other posts.
I started building an EV conversion recently using a 1981 KZ440 LTD cafe racer as a donor and have made some decent progress over the last few weeks. The drive system is now together and on the bench and I’m about to start the 12v wiring and the battery box fabrication. Just wanted to share what I’ve done so far as I’ve gone through a bit of pain in some areas and it may help other builders, plus I’ll have more questions so hoping to tap into some knowledge.
Overview for the conversion:
-1981 kz440 ltd with ktm duke 390 front end
-Custom adapted duke 390 brakes
-17” 8kw QS hub motor driven by a Kelly Controller
-24s NMC lipo pack @ 7.4kWh
-Thunderstruck tsm2500 charger with dilithium MCU, BMS and SOC meter
-Vicor 400W switch mode dc-dc converter
-8Ah antigravity 12v battery
-Motogadget mo.unit blue
-Motogadget motoscope pro
EST weight at ~140kg
I also put some videos together for the build if anyone is interested in checking them out. I ended up doing something a bit different with the drivetrain power so it may be of interest to some. The videos are a bit cringy as it’s my first attempt at anything like this so excuse the bad acting and terrible voiceover
