Modern Vespa

i've built some very mean yamaha's, but where do i find the best parts for a vespa?
best variator?
different clutch spring?
i want it too look stock and sound stock, but smoke the big bikes off the line.
any ideas?

The Polini put out the best numbers on paper. Verified 2 hp gain, with increase in top speed from 82.5mph to 91 mph.

Did you use the rollers that came with the variator?

Yes, the 11.8gr weights.

Max

Are we talking the 250 here or 300?

Best,

Mark

250. We use the same variator for 250 and 300, but use different weights. The 250 takes 11.8gr weights.

Duh, the clue's in the post title, I guess

Then that's what I will go with at the first opportunity too!

Best,

on a japanese you have 3 choices for a clutch spring. white yellow or the mean as hell red. is their something similar for a vespa?
i allways ran the red, which was about a 2,500 rpm stall.
