"camshafts are designed in conjunction with our racing efforts, and in turn the design gets passed down to our customers for the best power gains"
This is also from yuminashi's website so that explains one of them. Can you link he website where the specs were stated? If anything we can have fun using google translate.

No I'm not saying either. My numbers come from a site or company that offers two different camshafts for a 150i PCX. They are simply different grinds
Why limit ourselves to two. It's like Monty Python. How many sexes are there? Two. Its not enough we need more.
Either of the two will show you a flashy picture with statements like.
"It feels like 150cc+ and I achieve same acceleration of stock Pcx with only 1/4 throttle"
or "camshafts are designed in conjunction with our racing efforts, and in turn the design gets passed down to our customers for the best power gains"
The second one is interesting as the Internet is woefully missing any pictures of PCX racing. Unless of course all the racing is at night on unused roads in which case it is drag racing.
It doesn't hurt to publish cam specs as no one is going to rush out and produce cams with one or two degrees difference.
Just buy a camshaft and tune your variator to it. Or not...In any level of motorsport engines will have different cams and be tuned accordingly. One wins one day, another another day there is no absolute.
I'm starting to sound like GN2 here but it is not intentional
Best not to piss on their parade. Shooting, fish and barrels.

That's right You You fish and barrels not fish in barrels, that would be too easy...
All I can say is this snow is giving me wrenching time and no testing time.
