What should I install next?

Can you confirm if it’s the window piston or the better carburetor that got you’re bike going faster?

No, I can't, I put them on at the same time

Porting the intake and exhaust wider left and right will help allot but ull have to port your intake manifold I'm assuming as well

Do you remember roughly how much you’re top speed increased after installing those parts?

Well, it was a noticeable increase, I can't really say exactly how many mph extra I was getting at top end. It takes awhile to crank it up and get the RPMs that high to the very top end and I hardly ever let it wind up that long, only on long straights. I would say at least 5-8 mph faster. I can hit 50 mph on a good day but I usually just cruz between 30-40 mph, maybe hitting 45 on a long road. I'm using a 36 tooth rear sprocket.

Now that I think about it, I can get up to 40 mph pretty quickly, but to go from 40 to 50 mph takes a pretty long time holding it at wide open throttle.
