Compression is great.
So my guess if your one tooth off one or both cam's.

This is when pulling the engine makes checking cam position easy.
I didn't and went crazy trying to get them lined up. Looking at a mirror, with next to no clearance and seeing if they are across from each other is NUTS.
Which is why I assume PainfullySlo suggested pulling engine.
I didn't listen and wished I had. (won't happen again) live and learn.

If your intent on not taking to the shop, and your tensioner is about 5 clicks out give the mirror trick one more try. It still might be quicker pulling the engine.
Just don't forget exhaust gaskets.

That's a good start.

So I just found out I messed up an intake shim and it was way loose, rechecked my timing the best I could and it looked right. Startup still sounds like a chainsaw or weed wacker. It has a strong idle right at 1350 and I don't hear any misses. I know I've said this before but is it possible the cct is garbage?

My issue with the teeth on the cam is I'm counting 28 pins using the diagram in the service manual and if I move them either way it looks like one side would be low and the other high

If I remember correctly, riverzz said 5-6 clicks was normal.

The cams marks will face directly across from each other.
With the tensioner out place cams properly. Install chain with slack on the tensioner side.
Mark the positions of all, cam to chain.
Put carrier over cams.
This is were having help is sweet. Have helper hold cams and CHAIN to the cams, they can NOT move as you tighten down the carrier and they will want to move.
As you tighten down the carrier the cams will be opening some valves and want to twist the cam.

Get that rogue valve tweaked and see what happens. Good luck, will check back next week.

Well I adjusted the rogue valve and I also figured out the noise thanks to a YouTube video. It was the cam chain tensioner. I counted the teeth and realized the first time I took it out it was much further out so I manually adjusted it 2 teeth and the bike sounds like a motorcycle again. It's insane how that little part can make such a nasty noise. I'm still going to triple check everything and I have an ape cct on the way but I think all is well now. I appreciate everyone's help it made a significant difference so thanks guys!

Just a word of warning on the tensioner..... too tight to make the drive quiet accelerates the wear on the guides, which will make the drive noisy much more quickly. The chain is sawing on the plastic guides. Same sort of material as the final drive guide on top of the swing arm. You don't want that to have any more pressure on it than necessary to do the job.

Ape tensioners allow an owner to over tighten the cam chain. This makes it more likely that the guides will be damaged in pursuit of a 'quiet' cam drive....

the wear cannot be repaired, without removing the guides from the block of the motor.

the auto tensioner would be the better choice, IMHO..... Probability of excessive wear is managed a whole lot better.

Yeah I already ordered the ape so I'm in for that I'm just going to have to be very careful in adjusting it.
