I just read as much stuff in the search as I can stand about Bendix gears and I learned a lot. But despite the repair manual saying not to, many waspers insist on a light lubrication, something like a dry lube. I'm about to take mine out and clean it (the Bendix; what did you think I meant?) so what say you lot, lube or not?

It's fine not to lube a Bendix drive. If you do lube it I recommend Dri-slide. I've heard some say silicone grease is dry. It isn't. Many bicycle shops sell Dri-slide.

Somebody, jimc perhaps, will be along presently to chide you for not using the technical term for these, "sprag clutch," rather than "Bendix," and you will be even more popular at Vespa parties when you drop that phrase in casual conversation.

Chide away. I'm a huge fan of Vincent Bendix (born Bengtsson) and especially his brakes so Bendix it will always be, for me at least. Heck, I'm even a huge fan of William Bendix.

Those are two completely different mechanisms.

Xsbanks's 150 has a Bendix gear, which operates on a starter ring gear. My GTS has a Sprag clutch, which is a freewheel device concentric with the crankshaft.

Oh goody. Well, technically, this device is both. The Bendix is the leetle gear that is spun and moves forward by the spinning of the starter motor and engages the flywheel, allowing the starter to spin the engine. In a car, traditionally this is the entire device; when the engine started and over-ran the Bendix, it was spun back out of the orbit of the flywheel. On motorcycles there is also a one-way clutch mechanism called a spragg clutch which engages the flywheel and the Bendix and spins it. A small, high rpm starter motor with a reduction gear is employed to overcome the torque of the stationary engine. Small, light starter for a small, light engine. Without the spragg and the gear set you would need a much larger motor and larger battery as a starter. If you have a large vehicle like a Harley or a car you can carry all that extra simplicity.

Why do I never get invited to these Vespa parties?

I probably wouldn't. Why? Well for gears that are always engaged like a gear box etc I would but this is not the case here (I think?). Also the transmission case gets enough grime it it (mine does) that I'd not want the grease to collect that grime.

The only gears that are in constant mesh are the reduction gear, the big one at the circumference of the "Bendix" which is always in contact with the starter motor, hence the reason for a clutch. I think the lube issue is really whether to use a dry lube on it, which I will look at once I get mine out and cleaned. I totally agree that like a clock, over-servicing it will kill it.

I also recommended Dri-slide.
