Valve Shim Kit For V4 Engines 1.72-2.60mm
This aftermarket shim kit includes the 8.90mm* diameter valve shims that AF1 Racing has been using in shop owned bikes for several race seasons. After success with these shims, we've decided to offer them to our customers.
Kit includes three each of the following shim sizes:
*Please note: Aprilia valve shims measure 8.80mm in diameter. The shims in this kit measure 8.90mm in diameter. We at AF1 Racing have been using these shims in company owned racing V4's without issue for over 5 seasons.
**Please note that this is not the complete range of valve shim sizes. Aprilia lists the complete range of valve shim sizes as 1.75mm through 3.15mm, so this kit covers roughly the lower 2/3rds of Aprilia's range. To obtain a complete valve shim kit please see AF1 Racing Valve Shim Kit 1.72-3.15mm.
***Please note: AF1 Racing does not allow returns on partial kits. Swap-A-Shim, and shim exchange services are not provided. This product can not be returned.
