Yep, we're going on two weekends...

Was out of town all this past week. I got into it last Sunday. Hope to finish today. It is all apart again anyway.

I started from scratch by removing both cams and following the FSM instructions on installation. Set the crank at TDC for #1 cylinder. Manual sayso #1 lobes should be opposed on that position and the arrows on #4 should be aligned with the holes on the lobes. Here are the pics:

Sorry for the multiple post. Doing this from my phone and had to edit the first post. Any of you engine experts give me the nod on this?

I don't have the gasket for the side cover, so I can't go any further than to get the valve cover back on. Would just like some reassurance befor proceeding.

The crank is set correctly. Those are the correct marks..

**There should also be marks on the cam shaft gears that will align with the head surface.***THIS IS CRITICAL.

IDK if they face outward or inward, the manual should state that.

Also, all those marks should be nuts on when the CCT is installed as that takes up all the chain slack.

The forward run of the chain (from exhaust to crank should be taught)...

For my FZ6 as an example (almost identical set up)the marks face forward for the exhaust and rearward for the intake);

I will check the cam sprocket markings too. I would think with all the other references set they should be on too. they are on the outside of the sprocket, so seeing them with the engine installed is difficult. I also reengaged the CCT and rotated the crank and returned to TDC on #1 and everything is still on the mark.

If you have a small mirror (or the misses) has a small one, you may be able to sneak in there to verify.

The cams can be off a bunch just looking at the lobes. The lobes will give you a good idea, but the marks themselves are critical..

In the FZ6 manual, Yamaha INCORRECTLY has you turning the crank, counter clockwise (or backwards when checking).

I don't know about the FJR shop manual, but the crank should ALSO be turned forward, CLOCKWISE when checking marks (especially WITH THE CCT INSTALLED...Again, all the chain slop at the CCT..

I checked with a mirror and the marks are where they should be. The FSM does specify to only turn the crank clockwise. I think it all looks good. Just have to wait for the gasket and plugs I ordered.

Everything looks fine.You found that the marks was out of timing?

 

[RaYzerman19]

What they said...... Yes on verifying the marks on the outside end of the cam sprockets...... good to go.

 

[Intech]

Yes the exhaust cam was off. Not sure how I did that, but I learned a lot in the process.

Yep, it doesn't take just a second of a loose chain to jump a tooth.

You can throw that Chain cover temporarily on and do your TBS while waiting, especially with the shim change...

Not sure if you were aware, but the two dots on the tops of the two furthers right cams are also alignment marks. They need to be lined up with the two arrows on the tops of the camshaft caps when viewed from directly above. I found that easier to view than the ends of the cam sprockets with a mirror.

In the pictures it looks like it is now correct, but the photo is at a bit of an angle. Best when viewed from dead on above.

Yeah, the FSM is pretty clear on all the reference marks. Not only are the marks very difficult to see on the cam sprockets with the engine in the frame, but the cam lobe reference marks are difficult, too, with the angle of the head. I am going to continue to be anal and do one more check with a straight edge on the sprocket markings. I don't want to take it apart again!

Yeah it must have moved when I reinstalled somehow. I have learned a lot in this process. I will never put the cover back on with out checking the reference marks. Would have saved me a lot of time.

That is a good idea about putting the cover back on temporarily, but I still have to wait for the new plugs. If they come before the gasket that will be the plan.

Is there a club signature pic for learning this the hard way? Something like a timing chain wrapped around a broken stopwatch? I wonder how many of us would have one.

FWIW, You made the same mistake I did, not removing the oil pump cover. Only mine having been a Gen1, I was able to ride it for a couple of months before finally tearing back in as a last resort to solve my idle/fueling issues. I guess that really does prove the superiority of Gen1s.

Well, I would have ridden it if it STARTED!

I didn't take it off, because I used the rear tire to rotate the engine in 5th gear. If there were no adjustments required I wouldn't have had to mess with that cover.
