Putting the finishing touches on my wife's Vespa 100 Sport that I built for her.

I put a polini 130 and pipe on it and a 19/19 carb.

Can anyone ballpark me on the jet sizes?

Cheers

Here is what I would ball park you. Throw that carb out and get a Malossi 25mm carb and intake. What pipe are you running with it? You have a nice torque minded low end kit but make sure you finish the job! I have an '83 100 sport that was built on the cheap with the above mentioned and a Leo Vince pipe. She only runs about 60 (since I have yet to change to a 4 speed), but she'll ride one wheel down the block!

I put Keihin PE28 on My Special 90 with Polini 130 kit (with polini exhaust and 4 speed gearbox)

She can reach 110 ++ Kmh (according to other scooter side by side with my smalie), but I'm sure she can do more, but my feet allready shacking...

Main will probably be in the low 80's. Higher if you mod the air filter. Did u port?

At any rate, start high and work down. And don't worry about these guys who ignore the question to recommend or brag about other carbs. There is always more shit to spend money on and when u want it plenty of advice available. Just enjoy your setup and make it work.

Mine; DR 130/19mm/et3banana=76
DR 130/19mm/GPS exhaust=87 on a cold,cold day.(39 degrees)
current Polini 130/19mm polini reed/et3banana=87

This is all with a stock unmodified airbox. with the DR kit top speed was 48mph, but the kit was worn when I got it so....

w/ Polini/reed setup top speed is 55mph. Speeds indicated by "heartbreaker" radar sign near my home.

Oh, and stock VMA gearing.

Sorry, forgot to mention that the pipe was the polini also and I matched the cases to the cylinder with a dremel

Aw, come on man. Not bragging, just offering up something that it seemed may not have been thought of. Let's face it, 60 mph is nothing to brag about. Any anybody that has worked on or kitted a smallie knows that they are not the easiets to get back around to without completely removing the engine, at least if you are going to do a carb update. Just trying to help before they are finished!

Sorry, didn't mean to give you a hard time. Just struck a pet peeve of mine, like when somebody asks for pros and cons of Polini vs Malossi and somebody tells em a Falc is better. Well, no shit it's better, but it wasn't the question.

All that said, your advice is totally valid and worth considering. On the other hand, I think you can get decent results with a 19er without spending money on more parts. But as you said, no harm in offering some options.
