GY6 125-150 cam profiles

[noday]

BOOSTYCOM a french online scooter parts store lists cam profiles for the most common racing GY6 cams with graphs that show lift v duration in degrees

the graphs show up when you click on the individual cams

there is also a simulated graph of HP v RPM for the different cams

www.gy6.fr/pieces-racing-125cc/arbres-a-cames-racing/cat_130.html

if you use Google Chrome as a browser it will auto translate the web pages from french to english

I do not know of another source for this info and of course do not advocate buying from this source

I've seen that before Noday. Nice post. That guy really went into detail.

are you sure ?

the before I saw was from a french scooter forum last year where the poster used teeth on the cam v lift for the plot

www.scooterchinois.fr/modules/newbb/viewtopic.php?start=30&topic_id=3164&viewmode=flat&order=ASC&type=&mode=0

that forum is sponsored by BOOSTY and the thread is a few yrs old

the plots are quite similar

it looks like MS excel was used to generate the plots
