I'm coming up on the 16,000 mile service interval for my F4i, which means time for checking the valve clearances. I could do this myself on my old Ninja 250, but the shim-and-bucket system on the F4i is beyond my mechanical skills, so I want to have a professional do it. Any recommendations on mechanics or dealers in the greater Milwaukee, WI area that can be trusted to do the job right? Thanks for any guidance you Milwaukee folks out there can provide.
