Ma la mia domanda è...a quel regime, con un motore standard, non ti ritrovi con il pistone e mezza biella in mano da almeno 1500-1800 G/Min?

[Faggiano]

non se usi l' olio giusto ! uno mi arriva, lo monto e lo provo.
cercasi volontario con motore "fresco"

[ninja636]

io ho un extreme 140 con qualche ora....

[Faggiano]

ti faccio una proposta via PM.

[Tambu#24]

Faggy non é questione di lubrificazione... quello che voglio dire é che albero, biella, pistone e cuscinetti dei nostri motori sono troppo pesanti per ruotare a quel regime, cederebbero di sicuro a fatica con tutta l'inerzia che c'é in gioco! E poi ci vorrebbe un elettronica adatta che ti permetta di arrivare come minimo a 15k g/min, visto che il picco di potenza é così alto...non voglio spalare merda sui tuoi prodotti, sia chiaro da subito! Io ti stimo, ti ho anche fatto preparare il mio 170rs! É solo che il regime dichiarato mi lascia un pó perplesso...

[Faggiano]

infatti l' elettronica non è quella originale.
io il mio "vecchio" l' ho fatto sfrullare 12800 e problemi non ne ho avuti mai.
Testa TB preparata, ma basamento originale.

Faremo il test al banco (mi devo trovare un motore Lifan seminuovo) e poi si tireranno le somme.
Se si romperà... bhe lo sappiamo che le probabilità ci sono.

SOME ADDITIONAL WORDS OF INFORMATION;

The new Yuminashi H-240K camshaft with installed Anti-Kickback system is a high-lift camshaft that give an incredible mid to top end power curve with no great loss at the low end. This camshaft can push up to 14.300RPM at 19,9bhp on a 140 engine...

The set comes complete with a 28T or 32T cam sprocket and the SPHL Valve Springs that you need to install to avoid coil bind!...
The SPHL Valve Springs are also available as a separated set under part No.: 14751-FMI-000 to use in combination with other camshafts...

YUMINASHI H-240K CAMSHAFT CAN BE INSTALLED ON:

14100-NC1-132 HONDA NICE110 (With 32T sprocket 14321-NC1-000)
14100-NC1-128 HONDA HRC HEAD (With 28T sprocket 14321-FMJ-000)

14100-NC1-132 LIFAN "FMI" ENGINES 120cc (1P52FMI) - 125cc - 127cc - 138cc (1P54FMI) (With 32T sprocket 14321-NC1-000)
***Be carefull with the LIFAN 138cc engine, some people call this a LIFAN 140cc!!!

The 140cc is a Lifan "FMJ" engine type and easy to recognise because:
1) it has a 59mm stroke crankshaft,
2) the engine has "FMJ" on the crankcase as engine type,
3) it have a 28 Teeth sprocket in stead of a 32T sprocket and
4) a bigger 32mm camshaft bearing on the spark plug side...

**If you have a LIFAN "FMJ" engine with 59mm stroke, then you need to install the YUMINASHI L-240K camshaft (Part No.: 14100-FMJ-128) that includes the 28T cam sprocket 14321-FMJ-000)

14100-NC1-132 YX "FMJ" ENGINES 120cc - 125cc - 140cc (1P56FMJ) - 150cc (1P56FMJ-5) (With 32T sprocket 14321-NC1-100): This camshaft can be installed on all Honda style YX engines until 150cc... **Be carefull, a YX "FMJ" engine is not the same as a LIFAN "FMJ" engine...
