Go a good pipe first,its easy to mod any pipe,just make sure that it goes on a Morini engine.From what I've found all you need to look for is anything that'll go on Suzuki Address or italjet Formula 50 scooters.I personally wouldnt get a MRP pipe for it,unless you want the loudest scooter in town,I put a Tecnigas Next R on mine and it works very well,great mid range,with the right weight rollers in the variator,you just wind up the clutch to about 6500rpm and then let it go.Then go a good 70cc kit,,Polini,Malossi,stage6,for example ,they're all good,personally I've tried the Polini and Malossi kits and I like the Polini 70cc kit more,but its all up to the rider.Remember that it is tuning and what works for me may not work for you.
GOOD LUCK WITH IT,,,,ENJOY THE RIDE
