good info

the 03 450 R cam is proving to be a good choice for me

[motoxxx43]

excellent!

[KS_TrailRider]

Very good info, thanks!

[flattrackracerdad7]

awesome info im doing a trx450 build ,flattracker,and im looking for a cam,,,there are so many choices and alot of cams have the same or are very close in specs ,even the web cams are very close in specs to hot cams etc. thanks for the info

I've had personal experience with the 2002,2005 and 2007 450R cam in my 2006 450x with good results from all, the 2002 was the strongest by far but was very hard to ride at idle or small throttle openings, very good for wide open (full throttle). The 2005, was a good compromise, with good bottom, great mid and decent top end and the 2007 was the best for me, as I ride mostly hills, and tight single track with the occasional high speed fire road. Keep in mind, i'm not a racer anymore. So this is only my personal opinion.

I know that some of you are saying that you can't put the 2007 450r cam in a 2006 450x but you can, all you need to do is remove the old style De-comp and install the one from the 2007 along with the cam gear and it works fine. ?

[FORMA MOTO]

...and cam tower.

[peaceofwork]

any one know x cam specs?

[crazybrother]

...and cam tower.

Nope, the X cam tower works fine. All you do is remove the old De-Comp assembly. The parts are the same on both... (Cam Tower).

Any 08 450R cam specs?

[raganius]

hello guys.I just want to ask which hotcam is better in midrange stage1 or stage2
i very want power in midrange on my 08 crf450x

I would use a '05 or '08 R cam over a HotCams

[camman]

Hot Cams Stage 1 has more midrange. Much more than any OEM cam.

It's nice to know you have tried all the cams.............

 

Stage one HC merely moves the power band down in rpms.

It does not increase power, and in fact reduces peak power.

'05R cam has no change over stock until about 4800 rpms, where it starts to peak, and then peaks strongly from 5500 to 7000, and signs of a bit early. VERY strong midrange.

Yes I have dyno tested all of these cams on my eddy current Super Flow dyno. Stage 1 cam does in fact significanly increase total torque under the power curve compared to OEM.

That is interesting, as the (3) bikes I have ridden with the Stage one were pretty gutless at all rpms.

[camman]

Then they where installed incorrectly.

I concur...the HC Stage One just sucks...little more power than stock X, but not worth wasting time or money on...

[MrRong]

You really have to try not to get the cam installed correctly...and I mean really. The honda 450r series of motors are super simple to set the cam in and do the cam timing.

So Simple ... A Shaved Monkey could do it !
