[Rohit_Kumar]

can anyone help me with engine specifications of 2004 honda cbr 600rr?
specification required:
intake/exhaust port diameter.
intake/exhaust valve diameter.
profile of intake/exhaust port.
intake/exhaust valve opening and closing profile with crank angle.

is there any difference between 2004 and 2005 model with respect to above mentioned points?

If you can't find the information there (which it looks like you can't), I'd suggest that you call them. APE is one of the most knowledgeable resources that I know of when it comes to a question like that. Considering there was a major update (http://en.wikipedia.org/wiki/Honda_CBR600RR#2005_revision) to the CBR600RR in 2005 ("The midrange power was also increased."), I'm guessing the answer to your question is "yes."

Do a search for the factory service manual. I've been pleasantly surprised over the years when it comes to finding tech specs like the ones you're looking for.
