Okay so I made all of my Modifications and everything runs smoothly. I chopped the exhaust, and found out that in my previous post my problem was that my vacuum tubes weren't all connected to the right port (carb noob lol). Anyhow I plugged up all the proper ports and it was revving up fine until I still had a loss of power whenever cruising past 40 mph. Furball Zen mentioned how I should check the new air cone, and I didn't have a Dremel (or other tool) to cut the sheet metal to restrict air flow so I found an oil filter from a car cartridge type and was able to put it in the cone and now I can ride smoothly on the freeway at 75!

My problem is that whenever I decal my bike pops and backfires. Not only down hills but even during downshifting to slow down. How can I fix this?
