Well I found the regulator, it's under the right side panel, a bit of a PITA to access but not too bad.

I know for a fact I have draining somewhere because the new battery (still under warranty) only lasted a week.

Great explanation Robot. I have a later model 150LXie which seems to blow the headlight bulb frequently. Any hints you can include in your next video please

Picked up a 99 et4 that had been stolen and dumped in a lake. Owner retrieved it in the morning so damage minimal. I drained fuel, changed oil etc, cleaned carby, replaced battery. Was running great but now battery dead and keeps dying after being charged? Thanks for the video, I'll start applying your process to find the problem!

[@MrMLajoie]

would this problem cause your check engine light to come on?, even tho everything is working and sounding fine?

Hey Robot, here in UK i have the pre leader 1996 et4 125cc, could i change out piston and head and put on the Piaggio 150cc head and piston? and if so would i gain anything? cheers
