vespa gts 125 performance upgrade with CVT and rideability baseline
I am planning a vespa gts 125 performance upgrade for city riding, but the scooter already has a slightly tired launch. I would rather restore the CVT before throwing shiny parts at it.
I found this related page while comparing notes: vespa gts 125 performance upgrade. I wanted a practical thread before ordering parts.
Would you check belt width, roller flat spots, variator ramps, clutch dust, air filter, plug, valve clearance, brake drag, tire pressure and same-hill testing before upgrades?
