Hot Cams 7.48mm Complete Shim Kit HCSHIM01 for Honda CRF Kawasaki KX Suzuki RMZ Yamaha WR YZ Dirt Bikes

This product has all different sized shims. Perfect for My crf250x. If you dont know what youre doing then take it to a shop because of you get them wrong its bad for your engine!

It would be nice if there were a little tighter tolerances with the shims but they work. It is much easier to go with a kit like this than mess around with pulling the shims, going to a dealer and getting them one at a time. I ended up ordering a restocking kit for the range that I use the most of so that I had enough. When you have a V4 bike with 4 valves per cylinder, there are not enough shims to complete the job if you have a few cylinders in the same range. After borrowing this kit a couple times from fellow bikers, I broke down and bought my own kit.

Only problem i found was some shims were rusted very minor. Shims were marked as 3.00mm as example but with calipers I measured them as 2.97mm. Not a big deal for me but if you need the exact 3.00mm to make your clearance perfect you may have trouble. Very good overall experience! A++

This shim kit was a great buy just wish they had more shims especially the more common sizes.

Used a micrometer to measure the ones I used, they were all to spec. A few in the kit had rust though.

Kit worked perfectly as described, used it to adjust the valves on 07 r6. only 3 shims for each size which means you may need to do some creative math if you need more than 3 to get within the right range, but otherwise, clearly labeled, and organized, great kit!

Very happy about my purchase, im sure its worth every penny. Was very pleasantly surprised to find a small magnifying glass similar to a jewlers loupe in the box to read the fine and worn out print, very handy amazing touch.

Hard to see number if any at all.

Arrived safe and sound. I will have to use them soon and they will be indispensable.

I used these shims to do a valve job on my DOHC 2010 Kawsaki Ninja 250R. Worked great! No problems to report and as always Amazon and its affiliate shipped lightning fast. All my valves are happy now! Thanks guys. The shims seemed all to be within the sizes printed on the shims themselves. The kit was high quality and consisted of two parts bins full of shims. Great start for my home valve tuning needs. Recommend to those ninja 250 fans as was recommended to me.
