Cams grinding
Hey Guys Im new here.
->I was using search button.<-
Bt I didnt get clear answer.
I have zx12r from 2000.
I have pcIIIr with muzzy race map.
Tps mode done, K&N air filters and Akrapovic ti 4-1
with Yoshimura Ti Gp evo pipe.
Now I want to polish ports (matt effect intake and full mirror of exhaust).
But first I would like to grind my cams.
Please tell me how much should I grind them.
I will send them to special manufacture here but I would
like to tell them some specifcation. If I wont guy told me that he will grind them
softly as much as he can but not very hard.
Best Regards Tom

If your going to grind a cam grind the exhaust can only to .358 lift and 244 degrees of duration at. 050. The exhaust side needs some help. Basically put the intake can on the exhaust side. Degree your cams to 105/103 or 105/105....

You should also consider oversize exhaust valves as well. Go with a thin head gasket from cosmetic to bump the compression. 5 points. Added cammimg without compressiom gives you a lazy motor...

For this year (2012) I want to port head. Change valve springs for orient express ones.
grind cams (but I will have OEM ones so if this wont work properlly I will get back to OEM)
Spark plugs maybe gasket also.
But how will looks engine long life?
What does lazy motor mean?
Engine will be slower in getting on rpms?

no gain with bigger valves on a stock motor.
a better method of raising compressing ratio is to skim the head and use an oem gasket as this doesnt alter squish, only PTV.
bigger cams in a stock motor= less hp=lazy
raise the compression and degree stock cams for the best results.

So is there any good result form grinded/race cams in stock motor?
What about head porting is it good mode or better forget about it?

Disagree. The exhaust side of the head needs help. Iv'e seen good gains with oversize exhaust exhaust valves and exhaust porting. The intake side is really good.

care to back up that statement? before and after results same conditions
the exh port does need work where it meets the pipe IF you have an aftermarket pipe, but the valve size is fine for this application

did Jim suggest the stage 2? I thought it was generally for 1350cc ish and up? going with big enough cams to require 28mm buckets?

Is there sense to make head porting by hands 
I see all people do this CNC way but here in Poland
we dont have such opportunity.

Not sure how big of cams he is talking bout, but I asked bout a head n cam pkg for a street n occasional track day n that's what was suggested, maybe its not a really aggressive cam either the stage 2 head, on his website I saw a 1287 wit stage 2 head/cam making 213, not much difference between a 1270 to 1287, I've heard really good things bout jim n I can't c him steering me wrong, this is my last time going in motor so im praying its good, lol, unless someone comes through with a late Christmas list n buys it!

Do whatever Jim suggests. Im guessing lift will be a little under .400 for a street bike?

agressor,
Anything other than stock cams on a stock engine is a waste of money. You can't get to the extra revs they could provide. Any power gains are above 12,000. Raise the compression a bit as Scott suggests. Larger valves on anything smaller than a 1375 are non-productive and in fact will kill your bottom power.
Jim's head would be great IF you have higher compression, a way to re-map the ign and fuel, AND an exhaust that does not provide for good street performance, but top end power only.

It's not that I think you're dumb, it's just that so much of what you know isn't true....
