I was just going through an on-line parts fiche for my '07 and was looking at the page for Valves

https://www.yamahapartshouse.com/oemparts/a/yam/50045b32f8700209bc794018/valve

It lists something like 25 part numbers for Part #8 which are the various pad thicknesses (shims). It also lists three different valve lifters (buckets). Designated Green, Blue and Red. Anyone know what this is? There is even a different price for these. Didn't see anything in the FSM but admit I didn't look that carefully.

9 Lifter, Valve (O/S) UR GREEN 5EB-12153-09-00 $24.03

9 Lifter, Valve UR BLUE 5EB-12153-20-00 $22.40

9 Lifter, Valve UR RED 5EB-12153-30-00 $20.18

I remember there was a paint spot on the underside of the buckets.maybe the cylinder head have the same spot colour somewhere

The (O/S) indicates oversized. Harley Davidson uses this same format of naming when an engine case or cylinder head required more honing than standard spec to clean up. The differences with the other 2 I'm not sure.

 
Apparently, the color coding has to do with lifter bore diameter. Found an R1 reference -- but not much of anything else!https://www.r1-forum.com/forums/101-98-99-r1-mechanical-help/262039-99-valve-lifter-problem.html
Not much information out there.

Makes as much sense as anything. The FSM says to make sure that lifters are lubricated and replaced in the original positions and to make sure they move freely. The FSM also says to replace lifter (and head!) if the lifter is damaged. Nothing is said about mechanical tolerances or "color" choice (or even that there are differences). At least as far as I could see. Maybe its one of those super-secret mechanics things that they don't tell us peons in order to justify their $100/hr. service rate.

"Oh, you just ruined your cylinder head. Should have used the red lifter bucket, not the blue one. That will be $2000 to fix."

I too remember seeing the paint spot on the "inside" of the buckets. I'm glad that I kept them in order.

 
To add to your confusion, depends whose parts listing you use, you'll get different answers..... Partzilla lists only one up to 2012, then for GenIII it's a different one. Cheap Cycle parts lists 4 (blue, green, red, yellow) for 2012...... I'd say if in doubt get the nominal one (or original colour) for any bike if we know which one that is (i.e., not the oversize ones). The only other way is to order a selection and test fit. Why do you need one? They shouldn't wear out, constantly oiled.

I don't need one. I was just looking through the parts fiche (curious about valve seals, for no particular reason). I was surprised to encounter three different part numbers for the lifters. I had never heard that there were any choices and I couldn't find any reference to it in the FSM. If they are chosen for fit in the factory, it might be important for anyone doing shim changes to be REALLY certain that they don't mix them up!

 
This is a common tactic for main and rod bearings for the same reason. They are usually coded in some manner and replacement bearings need to be of the same code. This has to do with the sizing of the bore in the crankcase (main bearings) or bore in the connecting rod (rod bearings). On some engines I've worked on they use letters (A, B, etc.) for the size coding.

And by all means, be sure the buckets are carefully managed so they go back in the same holes. Very important.

Don't pull more than one bucket off at a time.
Unless you KNOW what shims are already in there, you pretty much have to pull all the buckets that have shims that need changing. That is unless you have a full shim kit in your shop (I don't) or don't mind making multiple trips to a dealer to get shims.

 
To keep the individual cylinder parts sorted I am selling specialized mechanics part trays. They don't scratch parts, absorbs oil and has easy finger access. Since this is the Forum I can make the trays available for $29.99. But wait --- there is more, for just $10 more I can also include wipes that keep both the mechanic's hands clean and removes dirt and oils from engine parts.

Hey, it is Friday.

That simply won't work! That's the three cylinder version - I need the four cylinder model. ($39.99?)
No dum-bass, that's just one half of the six cylinder version

. You know how this forum is with big pic posting.
I see now. I wonder if the picture is the intake valve model or the exhaust valve model? I wonder if you get both for the (very fair) price of $29.99 or if that is the individual kit price? Shipping included?

Ah, just spend the money on a kit of shims, especially since the size range is narrow, you can just get two or three of each size from Jake Wilson.

 
...individual kit price? Shipping included?
At this highly discounted price point it has to be sold as an individual kit. Shipping is free! But, there is a mandatory fee for handling and insurance of $25 per item ordered.

There is an outside chance that some of the mechanics on this Forum might, just might, have something similar in their household already which they could use as a similar parts holder.

No investment in special parts holder that you risk dumping off the table...... got my vote!!
Geez, I can't believe how some of the most inept and unimaginative people have been successful about working on their bikes. Look, if you worry about something as trivial as knocking your brand new expensive parts organizer off the table, simply put it on the floor. Problem solved, send beer. PM for address.

[/sarcastic humour] ['cept the beer part, that's serious :) )

Actually, I just use zip lock baggies labeled with a sharpie. Kinda for exactly the same reason- all parts stay together, secured.
