Shim sizes, universal?

Hey,

So I just went to my stealership to get a couple of shims and they have to order them, which is kind of annoying (especially after the guy told me I had an old bike, 99 yz400). I was wondering, will the shims for a newer 450 fit my 400? cause they might have that in stock.

I was wondering cause hotcams makes kits for the 400, 426, and 450, maybe they size the diameter just smaller to fit all?

Thanks for the help,

AVM

Yes, all year YZ,WR 400,426, and 450's use the same shims. The Yamaha part numbers are the same, so if you ask for 450 shims they're going to be the same thing.

The Hot Cams kit is a good deal (In my case, since I work on all types of machines) but I have had a few of their shims that were out of tolerance on the diameter and wouldn't fit in the valve spring retainer.

Screw the dealership you should've told that guy to . he just wants to try to get you into a new one so you can pay his paycheck.At least you don't have to worry about all that smog crap on your bike.I have a 98 yz400f and she runs like a dream:censored: :worthy::eek::worthy: :worthy:

Thank you much for the replies, I know what I will be doing tomorrow.... (getting my money back at the stealership)

I wonder what the hell their service department does when they have a valve adjustment customer?

Make people wait a week for a valve adjustment? That's bad!

That is excatly what I was thinking about and the reason why I cancelled my order tonight. I thought about asking him if the service department had some, but this meat wasn't hearing anything. This is at Wildside Yamaha in St. Charles, IL.

Just imagine sending your bike in for a tune-up (which they quoted me a while back at 300 bucks before parts..) and god knows how long! Ridiculous

Service "should" have there own shim boxes.

That's absolutely right!!!!!

If a customer walked into my shop and the parts guy told him he would need to order shims I'd give the guy the shims for free and tell the parts counterman to eat sh*t!

I don't know where you can get 300.00 for a "Race prep" with a valve adjustment? You are at the wrong place. 160.00 is more the correct price. It should be 2 hours for the valve adjustment including a race prep. That would be oil/oilfilter/air cleaner/air pressure in tires/ tighten spokes/adjust and lube chain/tighten nuts and bolts/ check running condition etc. It should only be 1.2 hours for the race prep and to check the valve clearance. Only 2 hours if the valves actually need to be adjusted. As far as that goes, Yamaha 's rarely need to be messed with. If you have a CRF on the other hand.......... If the valves need to be adjusted, its already to late....They are already "dished" and then you need a valve job/ new valves. If thats the case......3 hours of labor will get your WHOLE top end replaced, piston included. 300.00 for a Valve adjustment is ROBBERY and complete BullS#@#$^T!!!!!

$160.00 for a valve adjustment and the race prep? Heck, my bikes have never seen the inside of the shop, but for a price like that I might just save my time and knuckles. Where is this place?

Interestingly, Honda offers shims in increments of .025 mm as opposed to the standard .05 mm.

Probably because they have to reshim every few hours :thumbsup:

the only difference in vavle shims that I am aware of the between 250's and 450's I got a vavle him set for my 250 for like 79 bucks and its pretty huge the shim size between the motors is only different in diameter I believe

The problem with those shim kits is that you end up with a bunch of sizes you will never use.

Well I went to a different Yam shop and they guy went into his service department's shim kit to get some shims, very helpful guy, and he charged me 4 bucks per shim, compared to the crazy price that other places charges me (something like 6-7 bucks a piece). I made sure to cancel my order with the others and asked them if they have to order shims for customers... the guy didn't give me a straight answer, just turned around the pot.

A reputable shop will just swap out your old shims for the sizes you need. Glad you got it all sorted out!
