So as far as the Contra spring is there a specific color that I should get?
Now also understand that I haven't had a chance to look "under the hood" yet at my Sup9 and see what the previous owner did to it. It will keep a good constant 45mph on the flats and I can get to 55 on slight downhills. So I know something has been done to it so far.
My goal is more top end speed. I don't care about off the line as I really am not using this as a racer. I want to also have better constant speed when going up hills.
I plan on tearing apart the bike this weekend and looking into it and seeing what I already do have and then go from there.

The best suggestion I have is do a compression test, and see what you have. It should be 120psi or better.
Then as you said make a list of what is NON OEM on the bike.
45 flat sounds stock to me so you may have alot of options.
How does acceleration feel/sound? Do you have one steady rpm from a dead stop to full throttle? Or is there a point it feels like it "shifts" gear.
What are the top speed rpm's? What are the cruise speed rpm's? Factory carb/airbox? Factory pipe?
Most important... How much mulla ($$$) do you want to put into it?
No matter what you do to it 55-60 is about top speed for the engine/gearing. Josh or slinger would know if shorter gears are available.
Sooooo Bottom line is you can make more power, and get better Accel., higher cruise, and smoother transition of the cvt but to know where to begin you have to answer those questions i posted
