Basically I am still having problems with my 125cc scooter not starting and (possibly stupidly) I was wondering if a missing regulator/rectifier would be a key factor in this?!
The reg/rec charges the battery. You need it.
Check what voltage you’re getting to the coil and at the plug cap…there’s also tests for a reg/rec you can do easily.
If it’s getting spark (blue) and you’ve tried what I suggested before RE easy start, I’m not sure what to suggest! (apart from 'don’t buy crap scooters)
