same here, really hard to choose on these great cams... i really want CMS stage 2 but they said that i need to pocket my piston.. so hassle, i hope someone here will share on using CMS stage 2 cam with out piston pocketing... thanksIm having a hard time on choosing the right cams for me.
Im looking at UMA cams, Spec V cams and CMS cams.
My mechanic discouraged me of using Faito due to its cams that are easily damaged.
If you have opinions please share it.
Pocket the piston? Is that something like the piston getting shaved so that valves wont hit it? Cause my mechanic said that to me. Im all stock now. So im finding good parts for my first upgrade. He said when my cams, Valve springs, carb and cdi gets installed, why not port the head. And he added on that piston thing since he will open the machine.
valve pocketing in a stage 2 (high lift cams) is a safety precaution so as not to damaged your valves or in tagalog terms "tukod"

yes i agree with you... but in terms of pocketing, that is 4 pockets right?... do you think that will not loss more compression than gaining by using stage 2 cam? if this is the case i rather use stage 1 cam like kawahara. less hassle pa... hehe!
my mechanic said that he is going to remove a little part of the piston, is this maybe because of my cams upgrade that I'm planning? did not understand him clearly on that part but just maybe, this is his method so that valves wont hit the piston, but still not sure of what he said or I misunderstood him.
i heard rumors that the best cam was from YY Pang racing, Malaysia.. it's a limited edition.. I'm still searching for one..Im having a hard time on choosing the right cams for me.

Sir if you don't mine, can you share the valve pocket size? i mean ilang mm ba ang kinuha mo? thanksThere's a thread of malaysian here comparing all the aftermarket cams, he bought CMS,YYPANG,LHK,KAWAHARA. i dont remember the other brands, but he state that the CMS is the most powerful of them all, and thats what im using right now, im using it for almost 2 years, my piston has a pocket and there's no problem at all, my bike is daily driven, and can do drag too Hehe.. believe it or not its a stockbore stock stroke but can go 160kph on pump gas.. you can see the videos of me beating higher CC than me but sniper too, on facebook.. my golly dugo ilong ko HAHA
Sorry sir, dko alam kung ilang mm ung binawas nung mech ko eh.. ill ask nalang pag natambay ako sa shop..
so far so good both starting and top end acceleration. it doesn't sound like other cams do same as pour stock cam.
