A snakeskin cover for the seat would be nice... Maybe some of those old school streamers for the ends of the handle bars. I like baseball cards in the spokes too but that means you will have to buy some spoke wheels. Just answering what I read...

If you want performance upgrades... Pirelli Diablos.  You can modify the air box, and re jet the carb or add a free flow air filter and re-jet.

A free flow exhaust will compliment that.

Next I would get into the CVT. You can lighten the rollers or add Dr. Pulley type sliders. Perhaps chance the clutch to a Malossi, and adjust that for more low end RPM before take off. That will give you more torque to get better 0-30 times. All told I think you can gain 4-5 HP, and 1-2 seconds off of 0-30 MPH time, and perhaps 4-6 MPH more top end.

The streamers are my favorite addition tho. Not too many fellas go for them anymore. I think SissyMary has some. 8)

Is it EFI w/ a true throttle body or EFI w/ a Carb?

If its throttle body you can buy an ECU that will take care of fuel delivery, and ignition timing to several different pre set levels.
If it is the Carb. EFI then re-jetting is still a viable option.

Just looked it up.... Here's a pipe...

All better now.

 Please at least get the streamers.
