Customer photo review of 1988-2004 KX500 Billet Engine Cases

Amazing!!! Luke is so helpful. These cases are amazing and a direct fit of my old cases. All parts are equally made and not one is below my standards

1988-2004 KX500 Billet Engine Cases

The best machined pieces I have ever seen. I have wanted a two piece KX500 billet side cover for a long time and can't wait to install it. So trick!

1986-2004 KX500 Two-Piece Billet Side Cover

Very quick shipping, and super pleased with the quality of this stator cover! The anodized black blends nicely with the satin black powder coat on my KX500 engine.

Quality parts!!! Very happy with what I received for the money!! Fit and finish is top tier. Also happy to support a company who is helping keep these two strokes alive! I will be back for more parts soon!

Billet Rear Silencer Bracket | KX500 & KX250

Bearings were a perfect fit. A couple of shaft bearings were on back order, which I reicieved shortly after a majority of my orders arrived. Quality of everything is immaculate I would certainly do business with Luke again. I honestly wish I could have purchased the billet cases for my kx500af build after seeing the precision on the covers and head. Highly recommend TSO

I ordered the case saver for my 98 kx250, the price of the TSO case saver was very close to the same as the original kawasaki one. The difference is huge, The TSO case saver is made of stainless steel for extra strength and great looks. Shipping and customer service was very fast and included mounting hardware. First time I ordered from TSO, but it won't be my last. Thanks TSO for offering a quality part and great customer service!

1992–2004 KX250 Case Saver| 316 Stainless Steel

So the cylinder head is immaculate and performs perfectly with the decompression valve. Much much easier to start this 500cc 2 stroke. I just wish I the decompression valve was coming off the side instead of straight out the top. Decompression valve creates interference taking out the spark plug when everything is mounted and the bike is together. Purchased a new wrench to remove the spark plug and all is ok. Overall happy 😁
