WOOWH - its VERY strong!! even similiar level like pnp malossi 210. 65/22 is even to short. Idea city cruiser. timings and exhaust port of cyl are original.
pnp tuning: si24, vmc177, polini BOX exhaust, 65/22 transmission.
Better take a DRT 23 cogwheel for the 68 primary, 22 is a bit too short.
this PNP guide has 8 parts:
1) px 125 test ride
2) original px 125 acceleration
3) only polinibox!
4) what is PLUG AND PLAY tuning?
5) 1st start pnp VMC177
6) pnp VMC 177 tuning guide :D
7) acceleration VMC 177 pnp
8) VMC pnp acceleration vs original
9) VMC pnp vs pnp polini, tuning, FINEtuning...

Correct yes: head is wrongly mounted in the Video, the cut rips should be at 12 o clock, i did correct it before the testride.
i was asked in the comments, which setup do i recommend for a px 125, this one:
m1x (better piston) or vmc with mazzu or polini longstroke, si24 with 2,5mm mj bore, sip v2 fast flow tap, strengthened DIY cosa clutch, 65/23 transmission with box exhaust: megadella or polinibox BUT you need to set cylinder timing, with longstroke: head gasket & raising exhaust port edge, to get aprox 120/176 timings. intake (rotary valve pad) opening to the back. standard static ignition is fine. this engine will peak over 20hp at the wheel ;) a dyno curve from switzerland by sloboscooter is available on my fb page in the picture folder VMC 177.
