TT Polini Upgrade

Since upgrading the Bats Proven Performance Package from the Rose TP kit to the 85 Maxi kit we haven't addressed our outdated carb setup so we ordered a Polini setup to try. I love the packaging on the Polini parts and I can only imagine what it would be like to visit a motorcycle shop with a whole Polini aisle full of these parts! For the BPPP we are going with the Polini CP 21mm carb, Polini 360 intake kit, cable choke kit, and jet kits for main and pilot.



First up was inspecting the carb to see how beautifully made it is, changing the main jet, and documenting the beginning settings. The Polini jet kits come in these sweet little cases and have a nice selection to use for tuning.

Just like the lever choke on the previous Dellorto 21mm setup, I wanted to have the choke in the original location. The most elegant and simple solution was to machine the included bracket to fit behind a clutch cover case bolt just below the OEM Choke decal. I am trying to create a synergy between the best and rarest of the OEM Aprilia with the best and thought out performance upgrades. What do you think?
