So i broke in my hotcams stage 1 on my 400ex today, and holy hell, you guys arent kiddin....these things tick LOUD. Im gonna change the oil tomorrow and re-adjust the valves if needed. It just sound like a wrist watch ticking really fast and really loud when puttin around. Is their anything else i can do? I had the intake at .005, and exhaust at .006
And when i would let off the gas, it popped alot, am i rich or lean?

Lean, turn up the mixture screw. Yeah they do tick that loud, not much you can do about it, they get even louder once it warms up too. You should probably check your main and pilot jet as well, you are letting more air in and out now.

I ran a stg 1 for a year and yeah they're loud but thats fine. However your valve clearance is set wrong. Intake is .004mm and exhaust is .005mm.

its .004 and .005 or you can set them both at 005. They expande when warm so they will be fine set like that. I have the origanol sheet from my stage 1 hot cams right now and it says .004 and .005
my 400ex ticked rilly bad but after i got the valvs ajusted no more ticking.

i just started mine up again, and at idle it still ticks loud as SH^T!!!
My valves are set at .005 intake and .006 exhaust, and this fugger ticks as loud as my hmf pipe with no quit core or end cap at an idle
is it just that hondas tick loud, or is it like that with hotcams in all bikes?

your rocker arms could be worn since it is a 99 and if i was you i'd atleast adjust you valves both at .005 the manuals say .004 for intake and .005 for exhaust it could be ticking cuz their to loose possibly? i don't really no i jus no mine ticks pretty loud i adjusted my valves that took the ticking down but i dunno i might try all four of them at .005

You only need to remove the valve cover.

would that be enough room cause i know on my 300ex there isn't enough room to check out rockers

The rockers are attached to the valve cover (head cover) they come off with it.
The 'head' is where the valves and ports are.
The four covers over each valve are the 'valve adjustment caps'.
You just used the wrong word for the valve cover;)

what do i look for? Do i look at the contact place where the cam lobes hit the rocker arms? What condition should they be in/what will they look like if i need to replace them?
And where can i get new rocker arms if i need them, and can i put them in myself or would a shop have to specially do it?

you look at the lobes were the cam and rockers meet if there indented or chiped you need new ones
you can get stock rockers off of www.servicehonda.com or aftermarket harden rockers off of www.magicracing.com

yes stock rockers. The clearances are .005 intake and .006 exhaust thats what hotcams recommends. It seems to be more of a stage1 hotcam thing than a 400ex thing in general. The stage 1 just ticks loud so get used to it or get a stage 2.

I just installed a stage 1 a while before I sold my 400. I dreaded it b/c of what ppl said about the noise. When I put it in the ticking bothered me so bad I wouldn't ride it. So I readjusted the valves to stock settings, .010 and .012 mm and it had no noise to it whatsoever.

Well if there was NO noise what so ever its quite possible that the cam wasn't even letting the valves close all the way.

stock is .004intake and .005 exhaust, i believe.
Would it do any damage if i changed my valves with a hotcam from .005 to .004, and .006 to .005? Would i lose power?
i just wanna quiet this thing down alittle if possible, but im not gonna get rid of it or anything

k, so i should just get stock rockers then. But will worn or brand new rockers damage my cam? Can i install rockers myself or will a shop have to do it?
Holy crap ppl.
My 416 has stage 2 cam. it ticks louder than my lrd full exhaust at times. I have triple checked the whole valve train. Jeez ppl, learn to deal with it. You have to pay for power somewhares. Honda didn’t put that cam in it for a reason, IT IS LOUD. Learn to deal with it.
Every signal Honda 400ex w/ or w/o aftermarket cam has a tick sound.
as for the guy running .002 or w/e for a clearance, not smart. I bet your valves don’t seat properly, losing power fast.

The valves closed just fine. You got to remember most of you are talking in inches and I set mine in mm so it sounds a lot tighter then it is.

Yeah I understand the measurements, but theoretically if you hear NO NOSE, then it IS possible that the cam isn't letting the valves close very tightly.

Well, I didn't mean that the cam had absolutely no nise to it, but it wasn't just idling going tack tack tack like when I first started it. It had about the some or just a tad more than a stock cam. I also put the 450 timing chain in it at the same time. I would say that some of the noise that went away came from the old chain being wore.

Mine was loud even with the CRF chain. I adjusted my valves quite often to find them in spec 95% of the time.

My 300ex with a Webcam is pretty loud but not as loud as my Wb/hmf pipe.
