MZ/MuZ Riders

hello all. i put my bike back together this past few days and i noticed that the bike is not running. seems like the stater relay is not working. i did a bypass and got the stater motot to crank but i got sparks frm that. what can i do to test out the starter relay or fix it. does not seem repairable. thanks

I assume you have checked the interupt system? handle bar kill switch, side stand switch..

check the resistance of the pull in coil, I would guess it is around 20-40 ohms.
does it click when try to start?

that will get you started

yamaha relay part number 4KD-81940-00
is a direct replacement on my mz rt125 about $28 usd at
aftermarket atv shop

it may also work on your bike

unhook battery when changing

i'm not getting any power when the relay is installed. a few days a ago it was clickinh alot when i try to start it i asumed cause the battery was low. but it rode fine then i took apart the bike and tried to start is with no luck the killt switch on the handle bars is run and the kick stand is up tried to start it but absolutely no power. only time i had power to the starter was when i bypassed the relay and directly had the wires connect.
