Frequently Asked Questions
Contains 20 shims: 1 each of 0.10-1.00mm in 0.10mm increments, 2 each of 2.00mm, 2.50mm, 3.00mm.
Yes, highly recommended. Cam swaps often require different shim thicknesses to maintain proper valve clearance.
Primarily for Hot Cams kits on 4-stroke bikes with shim-under-bucket valvetrains, but sizes are standard.
Measure existing clearance with feeler gauges, then calculate: New shim = Old shim + (measured clearance - spec clearance).
