z50a k1 wiring/battery

Post by upnorth62 » Tue Mar 03, 2020 1:32 pm

I just bought another z50a k1 its the us version with a battery . the wiring loom is shot , I looked at shirebikes and repo ones selling for £60.
Can I run the bike with out a battery when new loom purchased?

My old Z50K1 fitted with a ST70 engine taken out to 88cc ran with a cut down ST70 loom, but 6V C50/70 loom could be used if you want.Battery was a bigger 6v type in a modded stock battery carrier.
Another one i build had only 1' of wire on the bike,black from engine to coil,no battery.
