I just got a GTS 300 and I'm loving the scooter so far, but I want to see if I can increase the performance a little.

I started by ordering a medium height Faco screen. The screen on there now is the tall Prima screen which protects well but doesn't look very aerodynamic.

As part of the maintenance, I thought I'd try a Malossi double sided red sponge and Iridium plugs. The plugs I have now are the double electrode type. I pulled the stock sponge, and it is already falling apart.

I don't know if I want to go so far as to replace the variator. I think I'll just try some Dr. Pulley sliders. Looks like 21x17 is the right size, but I"m not sure what would be the best weight.

I may also try a Malossi lambda emulator. I'm leaning against an aftermarket muffler (I am too old for a loud muffler), but I thought the emulator might still help.

Anyway, does anyone have any experience with different weight sliders? What is the best weight for the sliders?

Also, is the emulator a good idea or is that something that would make more sense with a more modified engine? I'm just doing little things here and there. Probably the ECU will compensate on its own for any additional air flow. If that is correct, am I throwing money out the window by getting an emulator?

Well, I tried the Malossi double sided red sponge and Iridium plugs; and that seemed to have a noticeable positive effect on performance. So I'm happy so far.

I also decided on 21x17 12g Dr. Pulley sliders for the variator. As soon as I get those installed, I'll report back with results....

Would agree with that statement. Couple 300s in my neighborhood running pipes and pod filters with stock ECU and no apparent issues.

Windscreen and Lambda Emulator
Today I added a Faco medium windscreen and Malossi Lambda Emulator. And that resulted in another positive increase in performance.

I am mostly interested in top speed, since I have to do a little highway driving to get from my house downtown. My GTS was doing about 72 mph top speed with no mods and the old full size Prima windshield.

I am 6' 250 lbs on a good day. The old windscreen was a barn door.

With the Faco medium windshield, Malossi Lambda Emulator, Malossi Sponge Filter and Iridium plug, I'm easily up over 80 mph. That's pretty good for less than a few hundred dollars worth of easy add ons.

I still have the stock exhaust. And I"m too old for loud pipes. So I may tear into the variator next....

I"m going to try Dr. Pulley Sliders next: 21x17 13g. with the Fuzzy Washer Mod.

I'll report back with results....
