You will want to tune your clutch. You can try kickstart springs, maybe flush at first since you have a stock cylinder and work your way in if needed, no more than 3 turns from flush.
Also, if you haven't yet, you will want to service your ignition components and set your points and timing, as they may have gone out of spec after many miles/years.
Most use a 2.17 atomizer with a 15 bing. Are you sure it reads 9.17?
Also, just a tip, when you wrap an exhaust you should wrap from the back to the front so that wind and road debris don't get caught in the folds and cause it to become loose and come off. (edited)
