Happy, I wouldn't get too excited about a larger rear pulley. While there is space for it, you will probably need a slightly longer belt. A larger rear pulley will just give you better take off, but by adding a slightly larger belt, might help ride up higher on the front pulley.
Anyway, an update, I did all my mods and noticed that take off speed from a stand still with the Polini and 8:44 to 1 gears was not as good as when it was stock or with the stock gears and big bore kit. I had ordered a new , well a used (345 miles) rear clutch as mine was about worn, I'd guess 80% worn. Thought about up'ing the clutch center spring and the 3 shoe springs. Well, clutch came in and I popped it in stock. Take off from stand still is now great. I credit it to several things.
1) While the clutch is stock, it is new and the springs are fresh.
2) Shoes are new and makes a perfect contact. My old shoes had maybe a 60% contact. See dark area on pads, the white area is a groove cut and did not make contact.
With the new lower gears, its obviously harder for the clutch to turn soooo, a clutch in good shape is a must. My old clutch had uneven wear as if something let loose inside and wore out a center section of all 3 shoes.
In any event, Take off now with the 8:44 to 1 and the Polini is as good maybe better initially , first few feet, and then much better than stock, hold on! Here is a few nice pics of bad clutch good clutch.
I am half way thru my 1 gal fuel run and then gonna check the oil tank to see how much oil it is injecting so stay tuned.
