Vespa Exhust+air filter+upjett - question

Eran /

I upgraded my vespa with a Simonini exhaust, i also drilled more holes in my air filter and opened up the "holes" behind the filter element, and switched to a #56 jet, the carb is a 12.12 and the stock jet was #49. i guess i see some improvement in performance but not when going uphill, hard to explain but seems like it drop revs and gets "exhausted" when going up.

is a mixture problem to rich\to lean?

beside doing plug chops is there anything else i can do to verify this?

Thanks

Eran
