Welcome to EMS Ducati. We are the source for Ducati 2 valve and 4 valve adjustment shim kits, the MBP Valve Retaining System, and valve adjustment tools. We are the world standard in aftermarket Desmodromic shims, tools and expertise. Each and every shim is 100% individually inspected and quality controlled, resulting in higher quality shims than OEM! We also feature purpose built valve adjustment tools so you can now do your own maintenance and save money.

EMSduc Merges with Desmo Times

With Mike’s retirement as “The Shim Guy”, I’m picking up the mantle for the production and distribution of Ducati Shims and valve adjustment products. While I work on adding Desmo Times products to Mike’s and creating a new website, feel free to visit www.desmotimes.com for your Ducati maintenance product needs.
