So it was last week I kinda vented in here my frustration .

I then found a great deal on a 250cc vespa GTS ie . I have to say what a day and night difference , going from 150cc carb to 250cc fuel injected . Besides rattling and clunking on bumps .

Well I have a few questions about the model stated above anyone in here have one so I can do some brain picking ?

Nice scoot.. if you can keep an exhaust on them.. the header pipes fail at the exhaust clamp and this then melts the rear brake line...There was a recall on them in 2007 and a deflector clamp and new type of gasket is used. The gasket MUST be replaced every time the header pipe/clamp is removed...like changing the rear wheel etc.

These are a few other issues and this website will fill you in on the details... full shop manuals etc.

thanks sprocket
should this scooter be ldleing smoothly , its rough . its an 07 with 3700 miles on . I was thinking running 2 or 3 tanks of gas to see if it will settle . I'm sure it sat and the gas in it was is border line . Any good suggestions ?

Seafoam.

Careful with the amount of sea foam

Probably needs an air/fuel mixture adjustment.. but rough idle is usually electrical...or timing.. valves etc...

Sprocket it fuel injected it auto adjusts , I checked on modern vespa the tach showing 3 bars is normal . Spark plug ?

So lurking around the vespa forums the 150cc vespa's I think they use a cvt carb with a acel pump .

Does it have an Ox sensor? If so , check the wiring.

[tvnacman]
