[gasolina77]

I'm about to purchase this 164cc kit for my bike http://www.yuminashi.eu/164cc-spl-power ... cx125-led/ but i just found out this 175cc piston http://www.yuminashi.eu/175cc-62mm-bore ... -150-head/ i'm wondering if i can replace this with the 164cc which is included in the set ? . It's on youtube that the 164cc kit could make the speed up to 150km/h so can this 175cc could get me to around 160 or 165 ? sorry for my english
mine is the 125cc version btw

You don't want to go 165km on a bike as light as the PCX. 100km is bad enough.

But, supposing you want to do it--modding an engine designed to do 100km when pouring its heart out so that it will do 65% more than its built-in best...what do you think that will do to the life expectancy of said engine. And what will it do to the machinery attached to that engine to carry it down the road?

Is this being a kill joy? Well, go for it anyway then, if you are mechanic enough to do the job right.

i already reach 110km on this bike i do want it a little more faster
.....as ppl said these parts are just plug and play so not many modification i think that won't damage much to the engine......i overclock like every parts of my computers, smart phone
thank for your comment bro but i think i will go for it
