removed and rebuilt the starter. Dirty commutator and brushes. When reinstalled, the starter just whirred and didn't crank. Since I wanted to inspect variator and replace belt I pulled the bendix and cleaned it. Looked to be in good shape. Put it all back together and starter still whirs and doesn't engage. I took side cover off again and had wife push start switch while I watched the bendix and though it spins, it doesn't engage variator gear. Ordered new bendix. Hope that fixes it. Any suggestions?

Had the same problem here on the LX150. To my surprise, in the end, it was the starter itself just being 'weak'. I guess the magnets had lost some mojo.

Thanks. If bending doesn't fix, I'll try starter next. I cleaned starter, sanded commutation and brushes. Seemed like it was working ok.

Heh.

I had thoroughly cleaned the commutator and ensured the motor was working fine - it made wood smoke quite effectively on the bench run! But it just wasn't fast or strong enough to throw the bendix out with enough force to stay engaged when trying to get the crank first turning.

Not that expensive, thank goodness. $50: https://scooterpartsco.com/ricambi/030-piaggio/piaggio-starter-motor-for-vespa-et4-lx-150-gt200

Thanks for the info. I ordered a starter. Cheap peace of mind. Hate to tear it down again.

Well, new bendix didn't fix it. Starter just spins and makes a "whirrrrr" sound. Waiting on the new starter. Hope that fixes it. I'm a pretty fair mechanic. Built BMW airheads and Sportsters for years. But I'm new to scooters. I'm stumped on this one.

According to Motovista (of scooterpartsco.com) Leader engined starters are renowned for going weak after many years, so they keep a good supply.

Well, it was the starter. I really appreciate your advice. I would never have thought that since I had serviced it and it bench tested fine. The starter from Scooterparts came in a already opened Piaggio wrapper but it's a Chinese manufacturer. No wonder it was half the price ScooterWest wanted. Anyway, it's starting like a champ. Thanks again

Has anybody managed to reuse one of these starters after disassembly? I got one working once but it sounded so sketchy I took it back out again. I suspect that once you decide one of those starters needs to be disassembled, it's time to get a new one.
