Hey, awesome video! I'm planning to do my valve shims and timing chain but I'm confused where do we match the dots on the cam shaft too? and how do I know if I set the chain properly?

The marks on the cam shafts will line up with the top of the cylinder head (shown at 4:00 in this video). When putting the chain back on, you need to have the timing mark on the flywheel cover aligned as well as both cams (shown at 12:44 in this video).

@@rmatvmcok so I get how the first dot matches with the top of the cylinder. But, still kind of confused what I align the second dot up with? Is it the any of the cam teeth?

Hello I took a few weeks ago to adjust my valves but uncover to change rings my question is if I change the valve seals do I have to re-adjust or are they still adjusted I just want to change seals to be a little calmer the valves are in good condition

As long as the valves are wearing evenly and you keep every part in it's same location, then it shouldn't need to be readjusted after changing stem seals. I would check them with the cylinder head still off the engine to be sure. That way you know if something is wrong or if you did need to make adjustments. - Wes

What did you use to hold the new valve cover gasket in place on the valve cover? Everytime I go to put it on the bike the gasket falls off the valve cover. Its a new gasket and new valve cover.

Valves are a good thing to check regularly but it doesn't sound like this is your issue. You could check your spark plug to make sure you're not running too lean which would cause the quad to run hot but it's normal for YFZs to have a red hot exhaust, especially when just idling.

Lets say there was such a thing as a race or non race version. Just to humor you. There isnt lol so jokes on you. On the ttr250 rather than the yz250f-r the valves are not cam over bucket. They are screw and lock nut. Because they dont rev as high as this bike. Totally different engine.

It is in a shop that sells merch and parts. They also repair. Most likely theres more wrong with it and they are using it as a display for videos.

You put the equation out wrong making it look complicated to the idiots in the comment section. You should have wrote out the literal equation A=(b-c)+D Then explained what each variable stood for. Now all your comments are saying dumb shit and no one learned anything. Good job tho
