    Noises are so hard to diagnose.

    There are some positives here, such as the fact that it isn't frozen, and it only happens at a certain spot in the rotation. The engine may be fixable by relatively simple means.

    I wouldn't try to start it at all, let's figure out the source first. The cam cover has to come off.

    Update:

    I found what looks like a valve shim in the clutch cover.

    Welcome to the site !! \:D/

    Can you post a picture of the item you found ??? , and did removing it stop the click noise ?? , which almost sounded to me like a decompressor sticking .... To post a pic you need a hosting site like IMGUR or something , to post a pic , upload it to the hosting site , then use the link provided for Message Boards and Forums , and paste the link in your post .....

    It will look like this:

    The pictures are not showing up , you are posting the link incorrectly , or using the wrong kind of link for the forum .....

    What are you using for a image hosting site ??

    If its Photobucket and you are not paying them , they disabled the ability to post pictures in forums unless you pay them $300 a year or something stupid to that effect ... if it is IMGUR then do it like I posted above and it should work , Image Shack is the same pay per use as Photobucket ... which is why I do not use either of them anymore and use IMGUR

    Well it would be interesting if it is a valve shim.
    The cam cover will have to come off to check the valve clearances.
    If it is not missing, then did someone drop it in the motor!

    My original post was removed after I tried to edit some grammar issues, so I'm going to repost the info and video.

    I just bought a 2014 crf250l that's been sitting for a few years. The o.p. said the bike started making a strange noise and he parked it and let it sit.

    I got it home and hooked a battery charger up and turned the motor over and I could clearly hear a strange popping noise coming from what sounded like the clutch area. I pulled the clutch cover off and spun it over by hand and found that the noise actually sounds like its coming from the upper portion of the head.

    Here is a video:

    Sure looks like a shim. The chances of someone dropping an extra shim in here is possible, but much more likely that it is one of the shims that were in service. The cam cover still has to come off, and if the valve train hasn't been pummeled into a mushroom, maybe the bike is just fine.

    You did not mention in your redo post , if the noise/click spot the engine had when turning over was still there after removing the part/shim (is what I would guess as well) ???

    Update:

    I pulled the valve cover and seen that the intake cam was tore up pretty bad.

    I pulled the cams and the roller rocker on the intake side is broke.

    Sorry I haven't posted an update. I dont necessary like that every post has to be approved and can take up to 24 hours, so I moved on over to thumpertalk.

    Thank you for replying with your findings \:D/

    Only the first 5 (which you have just completed) is subject to approval , the reason for this (unlike TT) is to prevent spammers from inundating this forum with Fake Passport SPAM and Porn , and other stuff that TT seems to not care much about and why those of us here stay and participate here and not TT , that and the crappy attitudes of a lot of "Keyboard Warriors" that have no other purpose but to start a argument seem to thrive on over there .... which is why I quit wasting my time over there years ago , I have received more info here than I ever did at TT ...EVER ... This place is a family and FRIENDLY oriented site and we as users hope it stays the way it is ..... I have seen your posts come up and they were approved as soon as they were seen , which is usually checked several times a day by someone here ......

    Sorry the required wait for the first 5 posts has dampened your interests in this site ...... But it is the ONLY way this site can remain SPAM and abuse free from internet trolls and people who seem to have the sole purpose of causing havoc and drama , which I can't stand and TT is full of ......If you choose to participate here and have more questions or concerns , feel free to post them , as the posts you make from here on out will show up right when you hit SUBMIT , as long as they are not derogatory to anyone (in which case then they would be flagged for review afterwards , but not prior to the post appearing) , and continue to contribute to this Family Oriented site which allows others who might possibly have the same issue a source to solve their issues as well ... whether you think so or not , your question and subsequent follow up may help someone else with your situation , and THAT is what this place is about ..... We are all users here and riders , that and only that is what this site is about , is helping out out riding brothers and sisters in the ability to continue to enjoy there time here and to hopefully , though sometimes falling short with trying to resolve someone else's issues , either try to solve their issues , or direct them to someone who can .... There is NO drama here and hopefully it will remain that way .... TT is another story and to me is nothing but drama and not worth the effort ... If you have no issues with anyone there , then you are free to go there , or here , no one here will resent or condemn you for that .......

    We hope you continue to feel welcome here and and that you also feel compelled to contribute with things you know or learn as well as when you need help .... Also please note that I have no affiliation with this site , other than I enjoy the atmosphere and found I have more in common with members here than I don't ... This place is like family to me , and to be honest , is almost the only family I have left , I feel welcome here and I know for a fact people here actually care about me as a person ........... TT not so much ........ I find more drama there than info , and that is sad , but that is the way that site has been since I first found it over 10 years ago ....... When I found this site , at around the same time , I noticed that it did not have that hostile or "I'm smarter than you" , degrading atmosphere , and I tended to spend more and more time here , because I got tired of arguing with people over their opinion and them spewing it as fact , when it was in fact incorrect info ....

    No one here will claim to know all , or claim to be smarter than anyone else , or act derogatorily against another person here , that is a fact .... Again (sorry I tend to ramble , everyone here that knows me is used to it :-~ ) You are more than welcome to post without restrictions from here on out (this was your 5th post which all new people are required to get thru the approval period in order to keep this site family friendly and a pleasant atmosphere and SPAM free ..... Again ... I hope you understand that this is not a continual requirement to have posts approved , the first 5 posts scrutiny goes for everyone that wants to join this site , it weeds out the SPAMMERS and shows that the posters intentions are sincere ............

    Again , sorry for the long response , but I did not want you to think that it is a constant requirement to be approved , just till its known you are here for the same reason we are ...... , and thank you for following up with your findings , hopefully someone else will be helped from it ....... ;)

    Jimdirt, thank you for taking the time to post that!

    I didn't know about the 5 post rule until now. My OP got removed after I edited it for grammar issues, that and every post having to be approved was a little discouraging, but I'm not going to stop posting here.

    How about some pictures!

    Good news is the valves didn't hit the piston.

    I had a hell of a time getting the throttle body out. I damn near took the whole bike apart getting it out.

    I've decided to try and find another motor instead of rebuilding this one. I can do it, I just dont like building or rebuilding engines.

    The bike has been sitting sense 2015, it was a little over a year old. It had been sitting in a barn with a couple goats jumping on and off of it and had goat poop all over it.

    Oh yeah, I paid $200 for it.
