I'm sending a PM to "kenny" for you about this.  He's probably the best source of info with first hand expierence of both Cams.

Thank you :thumbs:

The x-2 has a tighter lobe seperation than the x-4. That should translate into more top end, but have herd that people are seeing a nice gain all the way across.

Just like preddy said, combined with the X-4 being installed 4° stupid (VS the X-2). The engine seems to come alive. The stock rod stroke ratio is 1.6 which just seems to love as much cam as you can throw in it. It also loves to breathe. I know that sounds ridiculous, but these engines are way more sensitive to restriction than an engine with a higher R/S ratio. Keep in mind that higher compression ratios trend toward wider lobe seperation as well :thumbs:

So a h/c piston and the X-4 4 degrees retarted is turning out some great power? A headport and some +1valves
you got a great stock bore. :clap:

Didn't know if you were talking to me but that is where I noticed the most difference esp racing those banshee's. It seems to make a big difference on the top end :clap:

Cool, that what I though. Kenz said that the compression would KILL the top end. I feel that my top end is KILLER!!

All I can say on that is we would have to test it out. Get a Kenz stock/bore with what they want and race :thumbs:

exentix

dont know if this is correct or not, but from what devan was telling me, he said the x-2 has more a a 2 stroke rev to it, and the x4 is like a 4 stroke? he was originally gonna go with the x2 but decided against it and got the x4 instead and it seems to rev very fast

1badazz_700r

That is correct exentix. velociraptor did my head and installed my X-4 cam.He told me the  X-2 is quicker reving like a 2-stroke. The 2 cams are the same,except the X-2 has tighter lobe separation which results in faster rev. All i know is my X-4 and mods really made this thing scream :thumbs: I did go back to my 14t front and it really makes a differance,because my bottom end didnt feel quite as strong as before. It is know though :lol: (devan29) on other forum
