It's a Piaggio skipper 4T 125.

(not my image but it looks exactly like that)

It's been sitting around for years doing nothing, I've tried changing the petrol, spark plugs, charging the battery and trying to start it while moving but it wont have any of it.

Just wondering if there are any other common things that go wrong?

Thanx.

moo

I can't remember, I'll have to see tomoz now.


What are the possibilities for if it does or doesn't turn over?

I just cannot find any manuals on the bike online. Someone told me stator plate but I have no idea where that is as I cannot find directions on how to remove it.

If

it's been sat about for years it is possible the piston rings may of stuck, carb will more than likely need a strip clean and reassemble, if it's a two stroke (sorry don't know this scooters engine type) the crankcase oil seals may of become hardened and no longer allow for crankcase pressure to exist, required for the transfer of fuel in a two stroke.

HT system working and no arching in the lead to the plug cap, plug cap arching. Plug no longer working under cylinder pressure.
Any safety switches which are fitted are they working, or have they become seized.

Basically you are going to have to systematically go through each system and check all parts for correct function.




Jaffa I bloody heard that. Pardon.

common faults-

Spark plugs - Check if they're actually there
Fuses - Check they're there and not blown
Petrol - Engines need it

Piaggio Skipper 4t 125 four stroke year?

Hi Justbe

As everybody else suggests(carb clean,change fuel,check for a spark,check for compression,check air filter is clean and a mouse hasn't built a nest in the air box,it happens more than you think:winkie:.new full charged battery.).

Just a couple of points to consider,if you are trying to start the bike with just the kick start(is the battery flat?) then the auto choke will not work properly,also the fuel cock fitted at the bottom of the fuel tank is a diaphragm type,which needs suction(vacuum) from the inlet to allow fuel to flow.This may have stopped working over the time its been laid up. Good Luck

KCMC:tongue:
