MUYIDP 47-Piece 7.48mm Valve Shim Kit for Honda CRF/Kawasaki KX — 0.05mm Increment Steel Shims (1.20–3.50mm)

MUYIDP's 47-piece 7.48mm valve shim kit is a complete set of carburizing-steel shims in 0.05 mm increments, made to service valve clearance on a wide range of Honda, Kawasaki and other 250–1000cc motorcycles.

This shim assortment gives you every thickness from 1.20 mm to 3.50 mm in 0.05 mm steps, allowing precise valve lash adjustments without ordering single shims. Each shim has a stamped thickness marking for fast identification, and the 7.48 mm bore diameter fits popular shim-under-bucket and shim-over-bucket valve systems used on many sportbikes and off-road machines.

Which models does this kit fit and how wide is the compatibility?

The kit lists fitment for many Honda and Kawasaki models and is commonly used on CRF and KX 250 families plus an extensive roster of other Honda motorcycles. It also covers several Suzuki and Yamaha 250F models when the application calls for a 7.48 mm shim diameter. Always cross-check your engine's shim diameter and service manual before purchase.

• Designed for 7.48 mm shim bores used by Honda CRF250R/X and Kawasaki KX250F families
• Includes explicit fitment examples across Honda CB, CBR, CRF, Goldwing and more
• Also compatible with many Suzuki RMZ250 and Yamaha YZ/WR 250F models indicated by manufacturers
• Confirm with your motorcycle’s valve train specification to ensure correct diameter and thickness range

How are the shims organized and identified for faster valve service?

Each shim in the MUYIDP set is stamped with its thickness so you can rapidly pick the correct piece during measurement and reassembly. The set covers fine 0.05 mm increments, which helps you reach the precise clearance the service manual specifies without stacking or machining shims.

• 47 individual thicknesses from 1.20 mm to 3.50 mm in 0.05 mm steps
• Visible size marking on each shim for quick selection
• Standardized 7.48 mm inner diameter for direct interchange in compatible valve trains

What material and durability characteristics should I expect?

The shims are made from carburizing steel, a common choice for valve shims because it offers surface hardness and wear resistance after heat treatment. Properly installed and used within the recommended operating limits, these shims are suitable for routine valve maintenance and performance-oriented adjustment intervals.

• Carburizing steel construction for improved surface hardness
• Precision thickness control to maintain valve lash accuracy
• Suitable for repeated measurements and routine replacement during engine rebuilds

How do I use this kit during a valve adjustment session?

Measure valve clearance using feeler gauges and compare to the manufacturer’s spec, then select the shim thickness that brings the clearance into range. Replace the shim and recheck clearance; the 0.05 mm steps let you reach the target without excessive trial and error.

• Remove cam caps or buckets per service manual to access shims
• Measure current clearance, calculate required shim thickness change
• Select stamped shim and install, then verify final clearance

Who is this for: This MUYIDP 47-piece kit is aimed at motorcycle mechanics, backyard wrenchers and track-day riders who need a complete, finely graduated set of 7.48 mm valve shims. It’s especially useful if you service multiple bikes or want a single purchase that covers a wide thickness range—handy for shops, restorations and performance tuners who demand precise valve lash adjustments.
