No. You would pay $90 US retail for the kit, and even if you do ever actually use it, and all 5 valves needed adjustment, you might only need 3 or 4 shims. To make matters worse, the kits come with shims in two different ranges of sizes, larger and smaller. These include shims that you will absolutely never need, and the point at which one kit ends and the other begins is right in the middle of the range used in YZF's.

If you want to be ahead of the curve, pull the lifters one at a time to see what shims are there, and order one size smaller for each valve. Or, just wait until you actually need them and get them then. The same shims fit Honda CRF450's, so the dealers should have pleny of them.

Not sure what the availability of parts is like in Thailand, but where I am, the only sensible option was to buy the kit. At least when I do change them out, I won't have to wait 2 weeks (if not longer) for them to arrive. If, on the other hand you have easy access to dealers that have the parts in stock, then I wouldn't bother.

The '06 that I just did rings in has shims in it ranging from 179 to 187 (factory shims are available in .01mm increments). It is, then, conceivable that I would one day need shims as small as 170, or in rare cases, as large as 190. Beyond that, it would need a valve job.

The $90 full kit has 3 shims in each size from 120 to 350, so there are at least 54 shims in the kit that I would never use under any circumstance.

They make refill kits with 5 shims each from 150 to 175, and from 180 to 205. These are $36 each, and even if you bought one of each, it's still $20 cheaper to get more of each size in a range you would more likely use. You could probably get by with just the 150-175 kit. Something to think about if you think you just have to have it.

Good call - probably should have gone that route, but got a good deal on the kit at the time. Guess I could always use the extras to stop a wobbly table or two :lol:

The same shims fit the RMZ-450, KX450F, CRF450, and YZ450F, so there will most likely be a dealer near you that has some. When I swap cams and need shims, I just run down to a local shop and buy the ones I need. The guy there normally charges me about a dollar a shim.
