Charging/battery issue
27 Jul 2025 11:55Rode it about 10 miles back fine and wouldnt start the next day.
Battery was flat so i charged it in hope of it working (I have a smart charger) but this got me about 2 miles down the road before dying, which made for a slightly annoying walk back.
My problem is finding the right parts, the bike has a lithium ion battery (and antigravity 401) which is small but should be big enough. I believe the reg/rectifier is completely wrong (attached image) so was looking for a recommendation of one suitable for lithium ion and are all the stators the same for the 400 engine? As i will changing that out whilst im there as well

I would hold off throwing parts at it until you get the R/R sorted. There are two different types of charging system on the 400's. Since you have a separate rectifier in your hand I suspect yours had the early field coil charging system. This will need a very specific R/R and some wiring mods to make it work. You firstly need to establish which charging system you have (how many wires and what colour are they on the "regulator")
Ricks can advise you on which R/R you need once you know what you have

These were the instructions I got, im happy with the regulator as thats pretty plug and play, just need some guidance for the rectifier side, thanks for being patient with me 😂
