4-stroke 49cc scooter Control Variable transmission help?

First I would like to let you all know i have very little intentions of changing scooters even if it is a chinese "clone" being a student I couldn't afford anything more expensive. However I recently had to replace my belt. It snapped around 3100 miles, I hear is pretty good for a stock belt. I also did a few other changes to the transmission, however. Being one who has never had any real "experience" with any mechanics, I took alot of advice from my manufacturer and my local parts dealer. I took my rear clutch down,(and my variator) he told me it had plenty of "meat" left on it, but that the torque spring was not collapsing correctly. I lubricated it with a Dry Lubricant (iron clad) and worked it until the plate rotated like I was told it was supposed to (before it only collapsed, but not as nicely and not as easily). I also had to replace my ENTIRE Variator (I used the weights it came with, which appeared to look like newer versions of my old one, just not worn out) as my variator plate guide bars (those little metal things that stick out slightly for the guides) were completely twisted and destroyed. Finally I used emery cloth (sandpaper) on the rear clutch and clutch bell (was told to do this to increase friction between the two, only scuffed it until the "Glaze/shiny parts" were gone). After doing all of this I would have imagined that my bike would run faster and accelerate more quickly, however the opposite has happened, before it used to accelerate very quickly, and would max out in the mid 40s,and hit near 9,000 RPMs now it dogs on the lower RPMS, and i'm lucky to even hit 6,500 RPMs. Can anyone yze what I did wrong? I'm aware that this is a complex problem as even my manufacturer can't figure it out, and the dealer says it's running perfectly. I KNOW this baby has more power, where did it go?
