I am going to build a off road lx-150 with a lt150 motor (lower gearing) the frame is also a total loss according to ins. my plan is to keep the scoot stock but have it kick start only and only the things needed to run the scooter, such as frame, seat, motor, air box, and knoby tires. i am ordering a wiring harness from scooterwest to make it kickstart only.

yesterday i banged out the dents in the front (it hit a trucks bumper real bad) and today i primed and painted the frame, i have to motor and parts to keep me going for a few more days but i am going to have to wait on a gasket to change out the gear box

You can make a wiring harness with what you already have.

Connect the CDI module from the flywheel - as per the usual plug. then tap into the green and black wire.

Green and black OPEN circuit = engine run.
Green and black CLOSED circuit = engine stop.

Don't let the AC wires from the flywheel go short circuit on anything~!~

I am not sure if this works for scooter systems with imobiliser CDI.

Not going to weld in a cross support for a center tank? Try to get ahold of a gt front shock for higher ground clearence. Maybe a rear one too. Should be available from someone whose upgraded to bitubo. Pull that centerstand off too before mounting the engine. And your going to want urethane mounts if not straight up solid ones. And knobbies. Show us the Knobbies!

this scoot came from a salvage where they kinda raped the frame. the is no ecu, immbolizer, spedo, or lights. it kinda was left for dead. but i am trying to figure out what another peice i got off a different total is. it is a black box a little bigger than a deck of cards, i am wondering if this is the ecu. not sure. thanks for the tips, i am now told that i will need a battery even a small one to fire up the scoot, so keeping the electric start would be a good thing.

the knobbies are not at the first stop on my list of dealers. i found them out of SIP performance but not over in the us yet. i am going to call up powersport places and try and find some.
i have heard of the urethane mounts before. is this the motor mount we are talking of. i work at a place with cutting lazers so i can fabricate alot of things myself. thanks for the thoughts.

The black box you describe could be the CDI module - if it has a 4 pin plug on the base. You may also require a HT coil too.. then provided you have a connection to the stator (on the fanwheel side) it's a simple case of 4 wires and the engine should have spark when you kick it. The CDI does not need a battery for the engine to run on the carby versions of Vespa engine.

Red / white = ignition charge coil
Black / green = pickup coil

I like your idea of an off road LX scoot with no electrics - keeps it simple and mud proof !

i think that this is the ecu. or is this the immoblizer. thanks
once i find out what i am doing i would like to try to wire this myself. thanks for all the help!

*****it is the regulator, ok and the coil is the other pic i posted.
i guess i will need to buy a new ecu, the S should not have to be programed then? right?

In the photos it appears you have a voltage regulator and HT coil...

Looks like you need to track down a CDI module from somewhere - the 4 wire CDI does not have anti-theft, thats the one to get... you can buy aftermarket ignition modules from SIP etc... but my tip would be find a cheap secondhand one... depends on the engine you have

How much of the harness do you have ? you got the plug that goes into the stator ?

I recently finished a custom wire harness for an LX I am building - hence the details are still fresh in my mind. Vespa electrics are straight forward enough if you can use a multi meter. I can post the factory schematic if it helps.

yeah, i am going to try to track down a used one, as far as the wiring harness, it is complete, w/o the immoblizer and the ecu.
i called around and it seems the dealer can only order the ecu with the immoblizer. the ecu is like $150 and the immoblizer since i can't program it with out the keys, is another $80. so i am going to try to find something else. even the ecu for the S has an immoblizer in it for an aftermarket part, even though it is OEM.
i will try sip and see what they have

SIP have the part you need for $85 excluding delivery.. I guess you have a Piaggio 4T leader engine?
