02 CRF cam

[dpizz450]

i just bought a fully stock 05. wanting to mod it out. i dont want to do anything engine wise past intake, full exhaust, and a cam. i been reading up on the 02 crf cam. it looks just like the power im looking for. anyone tryed one of these? is it just a stock cam out of a crf? where can i get one and how does it compare to the hrc cam? thanks!

I run one in my 05.

Yup its the stock cam from an 02 CRF450R dirtbike.
And I think now the 03 is the same part number.
You can get one used or from service honda.

The 05 HRC is a top end cam, with a pretty lame mid range IMO.
The 02 CRF is a mid range cam.

Totally different, I've ran both. Unless you like revving the piss out it where ever you go, the HRC came isn't for you.
Perfect for drag racing tho =)

i run the crf in mine. with no lid,,hmf slip on,11.5 piston, it runs very strong and linear. smooth and powerful everywhere. very good combo correct jetting is important with these mods also

Those of you who run a crf came on your 450r, do you have to buy a crf carb for your quad, or are you able to use the one that comes on the quad? Im thinking about getting a cam for my 09.

The carb makes no difference for cam.
Can run whatever.

nope. no spring changes or anything. shim it correctly and hang on !

price range? what about an aftermarket 02 CRF cam? how would it be? I asume its the R cam not the X, the X's cam would be mild

Does this work in 06 + also

[brandonpeake]

this is the 250 cam right not the 450?

i didnt think the 250 cam would work?

Don't know anything about the CRF250 but the one everyone uses is the CRF450r cam.

[brandonpeake]

someone clarify who knows please if u can use a 250 cam in a 450, I would think not,

but the crf 450 02 cam is a good one

did they even make the 250 in 02?

[brandonpeake]

yeah i think i misread what was said about the cam
02CRF is a good cam

[pro-rider46]

250 will Not work, the 02 is a good cam, and i believe the 05 is a top end cam

So this will not work in the 08 model, Why Not?

There is something different with the decompressor on the 08.

yep, they switched them to on the cam chain side

[duke416ex]

The newer crf cams should work in the 08 cause they also switched to teh chain side for the decomp but I am not sure what year they switched the crf in or what advantages the crf cam would be.
