I am new to this site, but it seems ROCKING. I have a 1980 Vespa Grande Piaggio. I just took it out of storage and tried to get it running. I put some gas in it and it started right up. It was running well and I was able to cruise around for 15 minutes. After that, I parked it. 10 minutes later I tried to start it again, but it didn't want to run. It might run for 10 seconds now, at low power, and then shut off.
Last summer, it had a problem with leaking gas. It would empty its tank over night. After replacing the fuel line, it still leaks gas. I guess it may be something with the carb or the petcock?????? Anyway, I'm interested in modding it, so I can hang on the 30 mph roads around here. I'm shooting for close to 40 mph. Right now, when she's running well, she tops out at about 25 on flat ground.
I am looking for the easiest performance mods to get me up to 40mph.
From Zippy, I have picked out:
-Carb, DellOrto SHA 13/13 -Will this fix the leaking gas problem?
-Exhaust, Sito Plus OR slightly more expensive Polini Marmitta Exhaust
-Air Filter, Malossi Performance
-POSSIBLY -- Variator, Polini performance
Should I get a 43mm "kit" too?
AND, I am looking mainly for easy, bolt-on mods if possible. I am only fairly mechanically inclined.
Vespa is leaking gas.
Goal of close to 40mph top speed.
Will Dellorto Carb 13/13 fix this?
Which exhaust is better, the Sito Plus, or the Polini Marmitta?
Should I get a Polini Performance Variator?
Should I get a 43mm "kit"?
