Thanks and yes I have checked every connection. Today I pulled all the grounds and polished them with sandpaper, they were black and cruddy withwd-40 and water and grime....cleaned it all up, ordered a race cdi, (wanted one anyway) ran a permanent jumper from the cdi to the frame and cleaned the pickup coil magnet of rust and residue. When the new cdi arrives, I will run another ground from the negative terminal of the batt to the green prong on the coil and back to the frame.
If none of this works its the coil, need a performance one anyway..stipped off all the gauges and top plastic for a euro look, feels less clunky and cleaner.
crossing fingers
thanks for all the help

Awesome post. I dont have the meter set correctly i think, but I am getting power flow from the stator and also the pickup is reading as well. Glad i didnt cut it off. I willswap my coil next, i have one but it has twp prongs...mine has one and a gound that goes to a bolt next to it.
Im pretty sure its the cdi at this point but im pretty sure the stator and pickup arent shorted
Thanks Alley i feel like im geting closer to chasin it down

::)Well i got some toys and some interesting readings, I have 12v coming out of the cdi (black wire) I have no reading at the coil when starting or still. The orange wires from the stator read 2 and there is no voltage from the pickup coil at all? safe to say it is the pickupcoil? I have one but dont want to cut unless its true thanks Attachments:

Some questions as before i goto the store or scooter parts place.
I ran a jumper ground from cdi no dice. Then i realized i had a scooter to try out my "fried" stuff on.....first i tried my plug cap and boot on the 50cc....fat blue spark. (eliminated) Then i tried my cdi and the 50 had no spark. Then I replaced the stock cdi on the 50 and spark again....will the 150cc cdi fire on a 50cc bike?
I am just grounding the plug to the head to check,not firing it.
If a 150cc cdi will fire a plug on a 50 then my cdi is burnt and i need to go get a new one.
Thanks!!!!
Plug, boot and cap eliminated
cdi may be toast, wwas replced before and zip tied to the wrong area where i feel it got really wet.
what are your thoughts

Thanks Alley oop, you posts are like gold and Im sure there are a bunch of scooter owners that owe you one on here, me inluded
thanks
I will get a multi-meter today, I had one but my tools got stolen a while ago, I work as a scooter tech helper, so this is embarrasing but challenging to me, as my experience with electrics has some background but not enough. I am hoping with a meter and runing some new grounds that it will fire. It doesnt seem likely to me the cdi or coil or stator, it had intermitttent spark, so if it is one of those 3 im thinking cdi.
it will be a challenge...I plan to start my own emergency scooter business after selling my van .
So what is the general concensus? Is the main theory that the bike is not grounded, or does it sound like cdi or stator?
I guess i will see later when I follow the flow chart to narrow it down with the meter...(money is tight sometimes)
thanks and i wont ever ride a scooter in the rain again

I got this scooter as my first one. I know something about engines, I am a backyard mechanic without high tech tools. It was not running and had been sitting for some time. After some bypassing of switches, handlebar, killswitch, and some creative wiring it got power and no spark. After some time of messing with it and changing out plugs, I got a gsxr plug to fire on the head with a fat blue spark. I immediatly put the plug in and it fired....I was so happy I took it for a ride...it was doing 60 and it was raining hard. I went thru a few puddles doing 40 and it was still running when i got back. The next day, no spark. checked all connectors and blew them out and sparyed down with wd-40..still no spark. pulled stator cover to inspect for water/looks pretty clean without pulling flywheel. Dont have a multi meter at the house. Cant tell if stator is wet or shorted..clipped b/w wire to cdi, hotwired ignition, will check grounds tomorrow and run new ground from cdi to frame. please help me get some spark fellas!! How long would it take to "dry out? can i hold the wires that goto the coil and bump the starter to see if there is current? should i run all new grounds? or let it dry for a week? or light in on fire> Attachments:
