Torque engine for PAV40
i want to build engine base in px125 cases. is to carry pav40. 1 or 2 person
I wanto to use Pinasco crank 62mm , box exhaust and carburator S.I 26/26 or maybe S.I28. I allready have pinasco flytech in engine.
i need you help to decide to choose good torky cylinder. in my head i have this:
- pinasco magny cours : will land in +- 126/176 timings. i allready made one in 60mm crank and is really power in low and medium rpm
- Vmc stelvium : really powe
BGM177/187cc rotary valve with 60mm PX200 BGM Touring crankshaft (casing milled for wider 200cc crank web).
Cylinder with opened up transfer ports at the base, matched casing.
Exhaustport and diameter NOT modified.
Raised compression (12.3:1)
Std. port timings (~172°/122°, no base gasket, only 5mm Spacer to equalize longer rod of 200cc crankshaft)
Exhaust BigBox Touring (BBT)
Measured in 3rd gear.
Pulls easily a 24/62 straight primary gear on PX125 EFL gearing.
