I have a ET4 2001 1500 miles. Try to start starter clicks. Tap Doll-rod with hammer against starter and it works. Is the only option to replace starter? Scooteparts.co has them for like $45.00. I assume it is the starter because it works when I tap it.

Probably a good assumption, unless it's just a weak battery or the relay is bad.

The starters are quite difficult to reassemble once they've been taken apart - at least mine sure was - and there isn't much you or a shop can do to rebuild one for the $45 replacement cost. So you might as well just replace it.

My top tip if replacing would be to clean up and (ahead of time) spray penetrating oil on any fittings you'll need to undo to replace the starter motor.
(No need probably if scoot has never seen rain or salt).

I agree with Juan. It seems so many ET4 issues stem from/relate to a bad battery.

I saw a you tube video on rebuilding an ET4 starter. I'll see if I can find it. But I'd check that battery very thoroughly first.

I'd expect it to be a sticky Bendix gear way before a duff starter, especially with so few miles on it. I'm assuming the battery is new and fully charged, and all major electrical connections to the starter and relay are good.

Take off the transmission cover, remove the variator driving pulley and pull out the Bendix. I'd give it a thorough bath in kerosene (paraffin for the Brits) and dry it as well as possible with a shop rag. No need to add any lubricant. It should now flick in and out very freely.

Replace it and then the driving pulley, ensuring the belt is tucked well into the clutch before torquing up the driving pulley.

I ordered a new one from Scooterpartsco. I think that should fix the problem. Old bike a lot of sitting low mileage just not happy from lack of use. If not I will carry a hammer and doll rod in tool kit. Or sell it.

The electrical parts Piaggio uses tend to be as affected by age as by use. I have replaced a lot of Starters on Leader bikes. None of them had high or normal mileage.

And I've just replaced a starter on our LX190. It had a very large inrush/stall current, which pulled a good freshly charged battery down to 9V and lost so much in the (very clean) wiring that there was only about 5V left on the starter itself. New starter ran perfectly.

Hi jimc - did you diagnose this through the battery voltage test alone? Winding resistance? Some other test? I'm just curious what troubleshooting steps are used to conclude a faulty starter motor.

I did voltage drop tests across both the +ve and -ve feeds to the starter motor, and again across the motor itself to make sure all the readings added up sensibly.

With that much current going in, but with the motor running happily off-load, means that it has lost the torque required to spin an engine over. If they are fixed magnets inside (I haven't opened the old one up to look) then I suspect they've just lost most of their magnetism. If there are static windings, then there's probably a shorted turn somewhere in the motor - a certain killer.

It was noticeable that over some months, the starter was having difficulty getting the engine to wind over TDC, even with the compression lifter working properly. Once over that, it would usually just manage to start. However, eventually it just went "huh" and that was it.

The engine was also filthy after 40,000 miles plus, so I removed it (not a huge hassle on an air-cooled) and gave it all a good clean, adjusting the valves and replacing gaskets and filters as required, plus new rollers and belt and oil changes. Now purring like new - except better of course, being a 190. Razz emoticon
