Good deal on quality KTM valve shims

My daughter has a KTM 790 Duke, and it was time for a valve clearance inspection (15 K miles). If you're aware, KTM has had an issue with the camshafts on the 790/890 engines. I was curious as to the status of the cams, so I took her bike apart. Luckily, ALL of the valves were in spec, and the cam lobes looked great. We dodged the bullet with the KTM camshaft issue.That being said, i didn't use any of the shims, but I did measure both shim height and shim diameter of a number of shims, and all were within spec. So, IF you need them, you'll have good shims. If you don't need them, consider yourself lucky because that means that the engine is in good shape.

Works perfect for bmw water cooled r1200!

Good price on a nice set of shims. Wiseco is hard to beat for quality.

Not enough of the shims you need (E46 M3)

Good kit for what it is, but if you haven't adjusted the valves in a very long time or don't know history of the car, you need to buy 2. For an E46 M3 with 18 of the 24 valves needing adjustment I needed 4-6 of the sizes 2.20 - 2.28. Only 3 come in each kit. It works out to you spending money on tons of shims that you will likely never need or use, but it is what it is and 2x this kit is still vastly cheaper than OEM.

Great price for a quality product

If you do your own maintenance on your BMW R1250GSA, these are a great buy.If you've ever tried to get the right shim from your Motorrad dealer, you know the frustration I've experienced in the past.This all but eliminates that frustration and at a very reasonable price.

Great shims, but not many of them.

When doing the valve adjustments on my s54 I very quickly ran out of the sizes I needed since this only comes with 3 of each. The next time I do this job I will either order 2 kits or just extras of the 2.16 - 2.34 mm sizes. That seems to be the range you will use most often on the s54 specifically.

Does not have shims advertised

This kit states 3 shims of sizes. The picture from bottom of box (if you look close) has shims in every compartment....but when you receive you'll find several empty sizes. I called Wiesco, and they said we provide 21 sizes (there are 23 different size boxes) However, even on Weisco's own website - images I've included in this, it clearly shows "complete kit" and 3 shims in each of the 23 sizes.Just be aware - same as multiple others in reviews - kits aren't as pictured.

Not used yet but appears exactly what I need

Good assortment for hobby user 3 of each size well organized in storage container. Appear well made and did not cost a fortune. Did not need to replace a shim but will the next time I check.
