Hi,I own Malagutti F12R LC from 2008 with stock 50ccm cylinder,new dellorto PHBN LS 17.5 carb.,malossi multivar and malossi wild lion exhaust. I have few questions,to help tuning it: -what's good combination for main jet/needle for this setup (phbn ls comes with main jet 90 and needle A12,which only works fine if I remove pipe from airbox,which doesn't make sense for stock scooter without kit) -roller weight/contrast spring to get best powerband for wild lion (my weight 115kg),rev target?? (currently 6.5g rollers in multivar and stock spring) In general I'm not begginer in this, I have experience tuning piaggio scooter which I drove last 10 years..but with minarelli no experience. So if someone has similar setup I would appreciate to share,thank you  |

Sounds like the main jet is too big. The needle should be fine for your setup, just might need to move the position.
I would buy a pack of jets to help tune it. It should use the 6mm Dellorto jets, the same as the Piaggio scooters.

Acc is ok,revs are about 7500 max,with lighter rollers I get 500 more and final speed is 65-70km/h |

With that pipe it has a very wide low starting powerband
I like my Clutch engagement around 5k . So light or medium springs ( 1000 or 1500 rpm springs )
I set the weights so they engage about 500-1000 rpms less than peak rpms .
So between 7000-8500 rpms is what I have been targeting depending If I have a Stock Cylinder or 70cc.
That is my go to pipe for sport type builds .
On your side of the pond the Giannelli go and Polini Speed are the same pipe

On your side of the pond the Giannelli go and Polini Speed are the same pipe Hi Zino,I saw some of your posts about changing stock transmission in minareli to get better acc and more top speed...how about pairing my malossi multivar in front and tp torque driver 122mm back with different belt like polini 775x17.5x30 or polini speed belt for peugeot 764x17x32? Would it fit to my F12r without modifications,except adding shims? Now I have preety good acc but I miss that final speed like on my piaggio I drove before. |

Zeezy I did pair a multi var with a 122m pulley I reference it as a budget overrange in my zuma build I was very happy with it gave me that extra low gear for take off. polini belt 248.041 was a perfect fit front and back and has measurements of 775X17.5X30 Here is the thread that Ryan Ott started about the 122m pulley. 49ccscoot.proboards.com/thread/24543/top-performance-td-belt-length |
