    Well I upgraded my 2000 Aprilia RS 250 with a full Tyga Performance Exhaust system and also went to individual carb filters intead of the dreaded airbox.

    Stock was 280 front and 270 rear cyclinder. Tyga recommended up 1 in each, but that was to lean. Ended up with 300 in the front and 290 in the rear and moved the needle clip to the 3rd position on the slide. Stock pilots. And stock reed valves. Runs great now. Also note I am virtually at sea level on Okinawa. You may have to adjust if you live in a higher elevated region.
