2007 px125 restoration

[sam]

Hi guys,

I'm here for a bit of advice and help. I usually work on bigger bikes, restoring a NC30 and currently riding a Aprilia Tuono, and do all my own maint and servicing.

My friend has a 2007 PX125, and I hope to get it back on the road for him.

Someone had tried to steal it, about 10 years ago, damaging the ignition switch and some of the loom. It's a real shame, as it's a cool wee scoot.

It has stood in dry storage since then.

It's seems in good condition, with very low mileage, around 3000km.
It was left with the fuel switch turned on, and the battery left in it.

I'm struggling to find a wiring diagram for it.

I've cleaned it up changed the battery, and jumped the ignition switch to what should be ignition on (red and white together), and I'm getting nothing when I hit the starter(with clutch on or out). No lights on dash or anything.

If I try and kick start it, the fuel and headlamp light will illuminate on the clocks, and I also get a weak spark.

The right front indicator is also hanging loose. There is a brown wire going to the bulb holder. A black wire going to the loom, another black wire from the frame running to a connector. In addition there is a black\red wire with connector and a grey wire with connector both hanging loose. I'm not sure if these are related to the issues. It seems these px have quite odd looms.

I'm assuming all the fuel leaked down down through the carb by now.

I'm not looking to start it, I'm just concerned I'm not getting the starter to engage, and turn over.

Can anyone point me towards a wiring diagram for this model, or suggest a good plan of where I should start looking first.

Any help would be appreciated.

Cheers!

Hi and welcome. First of all, by saying wee scoot, you must be a northerner, plenty of them on here…. 🤠 And as for the dodgy wiring, you have an Aprilia, you should be used to it! 🤣

On a serious note, see this link below:/

This is for an older P range model, but it will give you a guideline at least. I wouldn’t worry about the electric start (assuming it’s got one), just start with the usual, fuel, spark etc. and try to kick it over.

If you disconnect the green wire from cdi it does away with the kill circuit and engine will start without it, as long as carb is clean and fuel is good ect

If you give me email address i can send you a wiring diagram.

As Adrian says, pull the outer green wire out of the cdi unit on the back of engine to kill the ignition circuit.

Check fuel flow, clean petrol tap, carb, fresh fuel, new plug/lead cap

Put some carb cleaner in bareel to help the first start

Have you checked for spark?

Check clutch is free.

Check stator readings.

I would get it started on the kickstart, then start looking at starter motor etc.
Strip starter motor and test off bike, check tooth ring on the flywheel.
