Follow the description link on the site..

When I went to the link it said that the item was not available yet.

That Is exactly what I've been looking/hoping for. I think with that, a silent sport exhaust, and a K&N intake, I'll have what I'm looking for; close to 300cc performance in a lightweight scoot. That's exciting

It's designed for tight wads who don't want to spend any money but like to get more power cheapest way. Adding 175cc barrel would definitely make it move much more rapidly...either way, stock 150 head is the weak point in tuning those engines hence redesigned head was made.

Will it work with the 175cc cylinder? I am thinking about which way to go, 175cc, 190cc, or just this head kit. Performance and proven reliability are equally important. I like the mini-ducati sound of the big bore kit, so I think I have to move to the bigger size engine.
This head kit seems was designed for high revving, with the higher compression ratio, isn't it?

Double up post

Best is to email Yuminashi for advice, they're only more than happy to help out with unbiased advice, from my experience,they never tried and at times even advised from wasting money on some things as it would be of little or no benefit to my ideas..

Is Yuminashi a Thailand brand? Made in Thailand? The word itself says that it is a japanese one, but I guess it is not!
I saw somewhere that their parts are not top-quality ones, they say yuminashi parts came with imperfections there and there.
But performance-wize, they work more aggresively than a Takegawa, are they?

I was riding motocross for some years, and I know that high-powered 250cc 4-stroke engines needs a rebuild every season, and the piston have to be changed after the each race because of the forced engine geometry, piston diameter, long stroke etc.. ! (as manual says). Usually the piston itself breaks the cylinder wall at the upper dead point.
So the seeking for maximum power in PCX may play an agry joke with the owner. I'd like to stay safe but have some noticable improvements.
Hmm..

Well,time will tell. Right now, high power she is,an angry beast unleashed from its cage more like it...
I don't race mine but I do give a bit here and there,so I don't think I'm stressing it that much. It's really nice to have all that extra power,popping wheelies just of throttle and being able to overtake at 65mph+ with great urgency like a mini sports bike...It's simply the fastest 160cc scooter bar none and quicker then some 300's..

Ok got it.

It's available now. Will it work in the 2013? I'll give it a whirl if it will?

What's the difference between V1 and V2 engines? Sorry for the dumb question, I just don't want to blow a bunch of money for something that isn't compatible.

V1- first gen 125cc Pcx
V2- 125-150cc 'ESP' Pcx
