Here is a video of the sound the front (closest to exhaust?) 2 valves are making.  They we're making a loud pop before, so I checked the clearances, which were grossly wrong. I got new shims according to the spreadsheet, and now they make this noise...this is driving me insane...can anyone please help me?

The noise only occurs as the valve buckets come up.  Also, sorry about the vibrate noise at the end, got a text

Do you have the plugs lose? Maybe it is air compression you're hearing. Try taking the plugs out? Are things still oiled up?

Plugs were tight, I tried taking the plugs out, it didn't make a difference. I don't think it's air compression...but I could be wrong, I just don't remember hearing the noise before when my bike was running.  Things we're oiled when they were apart, and when I'm cranking it now, it should be circulating oil. I did apply some oil on top of the valve buckets...should I try taking the buckets out and oiling them?

complete amateur thinking here .. not bike wrench royalty like adidas .. but .. that sounds like oily surfaces sucking apart and closing again (shoe stuck in the mud style kinda thing) or just the valves clicking closed cos its all tight fit now... you said it wasnt heard when bike was running... with the cover off like that?... just my thinking but if it was firing i doubt you would hear that noise even if it was there normally ..

to me its just a surprising sound cos the top cover is missing.. you should hear the clicky poppy weirdo noises that come off a 7 litre diesel truck motor when its wound over with the cover off during a rebuild!... almost like ball bearings were in there getting mashed up!

but i'm probably completely wrong and off track again... i'll shut up now

Hmm...kind of makes sense actually. I put the valve cover and such back on too, and I could still hear the noise. Maybe I'll try and start it and see what happens...

Well I gave that a whirl and I can't even get it to turn over. It cranks, but never actually turns over.  I tried using starting fluid and that didn't help.  It is getting spark, and they are new plugs, and there is fuel in the bowls that I can drain.  Hmm.

Shine a light through the spark plug hole and take a look through the intake and the exhaust when the valve on that side should be shut.  If you still see light, then your valves are not sealing.  You could also do a compression test to confirm.  How did it sound when you closed the valve cover up?

On the left side I saw light...so, does that mean I need to re-evaluate my shims? or??

It sounded more or less the same, just quieter when I closed the valve cover up.

any engine will make that sound with the valve cover off. its a combination of crankcase air movement as the pistons go up and down plus compression and a combination of inlet and exhaust outlet sounds . just check  valve shims are in correct clearance . stick the valve cover on and use it .OH also a bit of starter moter noise as well.

If you see light when the valve is supposed to be Fully Shut and your valve clearance is good....

Then I am going to assume a bent valve. (happened to me a few times)

IFFFF that is the case, and my trade goes through on Monday.

Then I will pull the valve you need out of one of my junk heads and send it to ya.

thats after you are 100% certain the valve is bent and thats all you need.

(edit)
some people usually say just go brand new.

But I've swapped valves before (used) and if they were not bent, had no problems.
and most of the time I didnt even have to Lap the new valves in after cleaning everything up. (as if they are fully sealed before lapping, I dont wanna mess with them)

May I add that checking the valves are actually supposed to be closed and not being activated by cam position is handy.. Just I know from truck engine work that it is a simple thing to overlook when you are stressing that the engine ain't right ..  .. Took me half hour to calm down and think about it ... Then I felt like a dumbass for not checking the cam position 1st

Sorry can you re-word that first part possibly? I dunno if I'm going crazy but I can't read it properly for the life of me for some reason...

Also Tombstone thanks for the advice, and especially the offer. I am going to double check the clearances tomorrow, and I'll let you know.

I think what he means is that as the camshaft turns, it lifts the valves. So it may be that you see light because the camshaft has the valve in the liften position. So maybe try turning the camshaft and rechecking? I don't pretend to know anything about engines. Thats just how I read his post.

Yep camaro deciphered it .. Just don't do what I did once when in a hurry and stressed . Don't forget to check the cam . Make sure that the cam lobe rotation position is not pushing the valve open a little when you do the light shine test .. I know the bike engine is much simpler than a 400 hp 6 cyl diesel truck motor ..

But when you test anything on a vehicle you try to prove the theory only when you have checked that all the default settings or positions are correct 

Which by the way was re proved by Adidas and a few others when suggesting tests for my flickering headlight awhile back .. Once I was calm and followed the wiring diagram properly with a multi meter I found the prob in couple minutes .. Which had taken me 3 days or so of swearing before!

Ohhh, yep, okay that makes perfect sense. Got it!
