Size range for stock DL-1000 valve shims?

Hi all,

I'm preparing to check the ol' valves on the '03 DL1000 I bought this weekend My assumption is that it has never been done and it has 23,000 miles.

Can you all chime in with what kind of stock sizes you came across when doing your first valve check? I'm hoping to get away with buying a shim refill kit instead of a whole giant kit, but I have to have a clue figuring out which one to purchase exactly.

I saw a thread that mentioned most of the 650's were around 1.6 to 1.75, but I haven't been able to find what the 1000 usually came with.

And I know a lot of dealers trade, but not mine

Thanks all... Craig

I just did mine.

All the exhaust shims were 290 (2.90mm) - I ended up swapping out for 285's.

The intakes were all in the 270's: odd stuff, too, like 273, 278. Swapped out for 265's and 270's, maybe a 275 in there, too.

After some confusion between parts and service, my local dealer realized they DO swap them. The service guys didn't know what I was talking about, the parts guy whipped out a huge box of shims which seemed to range from about 250 up to 300-something.

Interestingly, all the little compartments in the shim box had a few shims in them, but the "275" compartment was stuffed full. He threw my 273 and 278 in there, too, suggesting that Suzuki thinks 270-280 is the sweet spot.

Thanks for the info. I'll double check with the shop. I only talked to the parts dude. Maybe the guys in the shop will have a different story. Who knows?

Anyway, that was very helpful info. If the shop still can't help me out I'll have a better idea which refill to get.

I'll wait a day or two before I order to see if anyone else chimes in.

I found more info here:

Looks like I will need to get two refill kits, but that is still less expensive than the one big kit. 2.40-->2.65 and 2.70-->2.95.

They also have a larger quantity per size (5 each) than the big kit (3 each), so I think that's the way I'll go.

I'm going to order from here. The price per kit is low, and I've had good luck with them ordering for my GS850.

I'll try to post back when I'm done to let you know if they worked out fine. Might be a couple weeks.

I don't know if I'd go off my one data point... altho that link to VSRI sounds like his Vee was pretty close to mine. In any case, you won't know for sure until you open it up so you'll find out how you're situated kharma-wise.

I think it worked out that I didn't need to actually replace all the shims. That is, if I had a 290 that needed to go down to a 285, and on another valve I had a 285 that needed to go down to a 280... you get the idea.

I've heard that overhead cams (like in the Vee) tend to make valve clearances close up (as opposed to opening up). IOW, they will always LOSE clearance, never GAIN clearance. That being the case, you might want to target the high end of the spec instead of the middle.
If exhausts are .008" - .012" (going from memory, don't quote me on that), you'd want to shoot for .011" or .012" as opposed to .010". "Slappy valves are happy valves," I've heard.

EDIT: I can't stress this enough - I'm a noob and I don't know WTF I'm talking about. I'm also a faceless stranger on the internet - my suggestions are likely worth what you paid for them.

HaHa. Duly noted I'm no expert myself and won't hold anything against you or anyone else here. My only other experience with valve shims was an '81 Suzuki GS850. If I get in there and have the wrong sizes, so be it. Not the end of the world. Besides, it'll be my fault for not springing for the big kit

One of the other reasons to go on the loose end of the scale is that valves will tighten with age. Very, very rarely do they ever loosen up, at least in my experience.

DL1000K8

So what is it, am I a smart*** or a dumb***? Maybe I'm just an ***hole.

UPDATE: OK, I dug in and did the adjustments yesterday. I ended up getting by with just the 2.4-->2.65 kit. However, it was just by the skin of my teeth. I had to swap around a bunch of the stock ones like Steve68Steve did. I would recommend getting the larger refill kit also for any bike that has not had an adjustment yet where you don't know what's in there.

Mine apparently had NEVER been adjusted. I just bought with 22,000 on it. 3 were out of spec, and the other 5 were just BARELY in spec. I ended up swapping all 8. Now they are all in the upper end of the range.

The Secondary Throttle Bodies looked (to my eye) to be spot on so I didn't mess with them. I put in new Iridium plugs, air filter, and did a Throttle Body Sync. There is no doubt it runs much smoother in the lower RPMs now. Before the work, I was taking city corners in first because I couldn't do it smoothly in second. Now second is like butta. Overall, a big difference. Maybe it's just optimism or wishful thinking, but I'd swear the exhaust note sounds a little deeper too.
