If youn look at the top of your oil pump you will see were the chain was riding on top of it ,thats were alot of the shaving came from,pretty comin when the chain gets really stretched

Question I have I have a 2000 model 400 EX yes had a headgasket leak and on it it's starting to run fine I mean you just hit the button and fire right up that was leaking out of the head so I tore it down and put a new headgasket in and bow cover gasket and all that and I watched the video of several videos I had to put it in time in time the only thing I got I don't understand I put it to the T mark it's not completely lined up with the glue groove in the low eyesight and IA low eyesight and I was wondering does it have to be right in that eyesight right rush out of the groove part Or can it be just a little bit to the left but still be an eyesight and will that keep one from not running I don't understand why it's not running because it is fine it is fine and the vials are going up-and-down Going up-and-down like it's supposed to and it's fine but it will not start I don't understand what I'm doing wrong but the question I have I know the Cam globe's gotta face down and you got 2 time remarks on the Cam gear that's gonna be level with the head but what I don't understand I've done that and have the tea in the eyesight but it's not in the underneath the groove part of the eyesight and I was wondering does it have to be right on that mark Is that maybe why my 4 will not start not start please if you can help please please call me 270709 2868 I am really about ready to pull my hair out I just don't know what I'm doing wrong and I guess the main question I'm asking you is when I Linda cama and a low's been down and you see the T mark does it have to be directly underneath that little groove in the eyesight

Awesome step by step video. I have a 2007 400ex and looking to replace the timing chain. Do you have a parts list? thanks!

#portedhead bro love the step by step videos always nice to c and know how things get taking apart then properly put back together. keep up the great content my dude PEACE

#portedhead. Another great video I enjoy these step by step. A lot of info did u find out what those black plastics where? The ones in the case... Arturo Medina.

Why didnt you put the crf 450 chain in for the upgrade

What brand of timming chain do you use?

#portedhead!! Got to love a step by step

If I saw those big ass metal chunks in the oil screen I would assume the engine is toast. Is it not?

I had a whole lot of out in my couch cover what's that mean

Can you do this without taking off the cylinder

Wats name of pliers use to hold pressure plates

You like the 440 or the 426 more?

Do you have an actual shop? Or a way to contact you? I am having hell with my ex. It’s a lot easier to tell over phone rather than comment on here. Lol

Duh hell the fly wheel holder tool called 😂

No need to remove oil pump.

#portedhead The bottom end had a lot of junk in it
