Hey Everyone, so we have a bunch of misc. scooters, but the wife and I just picked up our first “legit” Vespa’s.
She got a GT200l
And I a Stella 150.
Both have a few issues, but the Stella is a mess.
It is a 2005 150 with, I am told big bore kit.
Looking at it, I believe it to be a Pinasco as it is an aluminum cylinder, and the head appears to match what I have seen of them too.
The motor starts and idles great, but has NO top end power at all, and sputters it’s way to a top speed of maybe 40mph.
I did a proper 4th gear plug chop and the plug looks about perfect.
I have the 20/20 carb (totally open to changing it out).
I cleaned the jets and filter, but (like a dummy) did not look at the jet sizes. I will correct that today.
Anyone have some experience with these kits and the proper tuning/install of them?
Thanks for your assistance!
