Currently working my way through my To-Do list and attaching the throttle cable.
When connected does the throttle grip snap back into place like its on a spring? or do you have to twist it yourself on and off?
Mine feels like there is no tension for it to spring back into place and wasn't sure if this was how they worked on vintage bikes

On my Vespa GL there is no return spring at the twist grip, the cable is nice and smooth and uses the spring from the slide in the carb to pull the twist grip back to idle position.

I believe on the older type Vespa's, pre indicator models the throttle isn't meant to spring back so you can set the revs whilst you use your right hand to signal.
I might have just made that up but it sounds familiar 😋

That actually makes sense Shaunbond - I'll call it the "Italian Cruise Control" feature

Indeed it's a good idea if the throttle doesn't spring shut, if you have no indicators; it still bugs me, though! I don't think this feature was ever designed into the earlier Vespas, it just seems to rely on drag in the cable and a weak return spring at the slide. It is possible to get a throttle that snaps shut, and I've spent hours in the past with cable routing, lubrication etc to achieve this. As I will with my current machine, and worry about the consequences later!  |
