What stg hotcam is in your 416, 426?

[EXDUNER127]

What cam and how do you like it, i am debating to put either a stg1 or stg2 hotcam in my 426 and cant decide what to do?

[Natertot426ex]

I put a Stage 2 in mine and I like it a lot and I ride in all conditions.

[Silverfox@C&DRacing]

Same here I ride xc and mx with my stg2

[duke416ex]

Go to the website on is for woods and trail, which will give you more torque, the other is more for mx which will give you more top end. They have different lifts and duration, it all just depends on which you would rather have.

Does'nt stg. 1 give you low end power and stg. 2 gives you mid-top end power right>?? there is a stage 3 right? Whats that do? Would it be a good idea to put one on my bike< mostly stock...if you look down on my info thats all I have on it right now. Would a hotcam make my bike less reliable??

[duke416ex]

I have never heard of a stage 3, it wouldn't hurt the reliability if it is installed and broken in right, and I can't see putting one in a bike if you don't have an exhaust and air filter, and you will have to have jet work.

[240GNCC400]

get an exhaust first. when you go to do the cam (i use the stage 2) it wouldnt be a bad idea to go with an 11:1 piston as well.

[hondarider2006]

I run a stg. 2 in my 426 and ride all conditions, and I love it:D

[F-16Guy]

I'd go with the stage 2. Any loss of bottom end due to cam duration is made up (plus some) by the increased displacement and compression ratio.

Yes I have just started seeing the stage 3's advertised. I was wondering what they do as well. They are prolly just an all out drag racing one. Anyone know for sure???

PM C&D racing...they should know;)

[Buffalo400]

Does somebody have a dyno run to compare stage 1 and stage 2? It will be so great!

excuse me but I can't find the hotcam official website?

thank a lot

[400exrider707]

Ok heres the deal with the stage 3 hotcam for 400ex's http://www.exriders.com/vbb/showthread.php?s=&threadid=148512&perpage=15&pagenumber=2

[mx400]

was just getting ready to post that. the stage 3 cam is the old stage 2 mx cam. they are developing a new stage 2 cam that is supposed to be in between the xc and mx cams.

[sportraxkid]

I run the stage II with my 11.1 440.

Get an HRC cam and get better performance than both Hotcams put together....:macho

How much do the HRC cams run for??

[Z-Racer-5c]

Webb Cams are the way to go!! But like they said before if that is all you are doing it will not help much. you need exhaust and air filter first then do the cam. It helps the quad breath and will not help unless the air has a place to go!!

[Buffalo400]

Webcam need harder rockers and hotcam stage 2, no...
but, the hotcam stage 2 cam could be more breakable?

I think I will go with the webcam with 4 harder rockers...

Have you already problem with de hotcam stage 2?

thanks!

[JDiablo]

i heard that the hotcams make loud ticking noises?is this true?

[cals400ex]

the hotcams have been re-built. they seem to be great now. i have bought a few of them and never had a single problem.

the stage 1 hotcam does tick loud. the stage 2 (maybe they call it the stage 3 now, i am not sure), is nice and quiet.


for the price of the hotcam, it can't be beat.

[Z-Racer-5c]

The Hot Cams are built up and re ground unless it says new cam. How would the Web cam need a harder rocker?? I dont understand the physics behind that one??? Please explain! The biggest thing I have found as a differance with the webb cam is that the lift is lower but the duration is longer than the hot cam. I had the Hot cams on my KFX-453 and checked the grind on both. the lobe centers were smaller on the Webb cam which made me shim the tappett on the valve for proper clearance but the lift was less and duration was longer on the Webb. Also the degree at which the lift starts is a little sooner on the webb. I like the webb cams because all of them are new cams. The only Problem I have heard of with the webb cams is the clearance between the shaft and the gear is a little shy of what it should be and needs to be tacked with a welder to insure it does not slip. I had mine checked and there was .002" interfearance when there should be between .005" to .007" of interfearance. That is the only bad thing I have heard of. By the way the power of the webb cam is way better than the Hot cam. Just my 2 cents.

i run a idk what stage cuz it is a tmm old school added metal cam but soon to be a stage 2 cuz this one is showing wear and break down so i got a new stage 2 in the mail

Because the web cam is made of a harder metal than the rockers so it will eat the rockers up. Hardened rockers cost over $200 also, so if your looking at a web cam that needs the rockers your cost just went way up.

That's why drop in cams are such an easier install and better on the wallet.

HRC and Hotcams are drop in.

You can find them for about $300 or less. About twice as much as a hotcam but it is a HONDA designed product, built by Honda and it gives a huge boost to the 400ex motor.

[Z-Racer-5c]

It would seem to be a lubrication problem not a Rockwell hardness problem. If your quad is eating up rocker arms you should check on the lube oil system or check the finish on the cam lobes to see that it is good finish. Take a jourhal bearing for instance. They are made of Babbit which can be scratched with a fingernail. The journal runs on it fine, and does not burn it up as long as there is oil. On my KFX-453 the journal for the cam is alum. The Tappets for the valves are stock and no wear is evident. I am not trying to start something but this is somethin I deal with every day on a much larger scale and it has absolutly no effect on the rockers what the hardness of the cam is. JUST MY 2 CENTS.

Thanks

uhm u dont have rockers kfx/z400s are direct contact cams they push directly on the valves:rolleyes: and it does matter you will need a harder set of rockers if yougat a harder cam fyi:o ;)

You didn't see me say I had rockers DID YOU?????? And no they do not push on the valve directly. The valve has a shim to adjust the valve lash and a Tappet sits on to of it, which runs under the cam.

OK now tell me why! From an engineering point of view! Not just because you said so. If the lube oil system is working properly the rocker never comes in contact with the cam! It's called oil wedge. That is the foundation for most oiling systems.
