Hi Guys!

For GTS 300ie

Which is the better first upgrade?

Polini/Malossi variator set OR the LV/Malossi pipe?

The one that would give more noticeable gain in performance (speed/acceleration).

Thanks

Exhaust gives NO performance upgrade - the closed-loop f.i. system sees to that, unless you bypass it.

Variator - perhaps, but beware of maintenance costs (I've had both J Costa and Malossi wear the centre bushing causing problems).

Best bang for buck, by far, is to replace the OEM rollers with Dr Pulley sliders. Their variator and clutch offerings could be worth a look too.

have used 4 different variators on our GTS:
Piaggio - okay
Malossi - better
Polini 6 - better still
Polini 9 - best yet

also 3 exhausts:
Piaggio GTS - too quiet for LaLa + recalled fire hazard, heavy & rusty
PM Tuning 68 - nice growl, small performance boost at high speeds
PM Tuning 80 Scomadi - more refined growl, tangible performance boost at lower speeds

...variator first?

best

Hey thanks. Looks like my plan of attack will be: dr. pulleys (simplest), variator and then pipe. I'll let the mods grow on me before pulling the trigger on the next one.

Interesting note on the pipe. Few posts I've read have done the exhaust first (i think)?

If I had a GTS 300 my order of performance upgrades would be:

0. Digital tach
1. Up-gear
2. Dr pulley sliders
3. Air Filter mod - picture and measurements added.
4. Malossi V4 Head
5. PM68 Exhaust

In my opinion this order gives the best bang for the buck at each step and the only one that you are likely to have to revisit is the weight of the sliders to match the increase in power in stage 4 and 5.

Best upgrades for GTS

1. Tires (stock Savas are garbage)
2. Shocks and Bushings (makes scooter much more stable and predictable)
3. Front Brake Caliper to Brembo (adds more rider confidence)
4. Dr. Pulley Sliders (better performance)
5. Replace Stock Exhaust (stock unit prone to rust, graphite exhaust bearing is shjt and stock exhaust is too stealth)
6. Malossi Cylinder Head (transforms bike into beast-for scooter)[/list]

Do the Arkrapovic Exhaust, ECU Tune

I had mine done before I picked up the bike. My Friend with a GTS lasted about 30 days and he had to make the same changes was tired of getting left behind.

I did Airbox Mod, and Malossi Double Sponge Filter. I did not cut the extra loop to bypass filtered Air.

I have the Malossi Variator but I have not installed it or the Delta Clutch.

On the ECU Tune, AF1 preformed this for me. They advanced the timing, and re-mapped the fuel profile to eliminate the lean condition that the bike was delivered with from the factory.
