Yesterday I finally got around to making a manometer so I could sync the throttle bodies on my K5 SV650S. It was really pretty simple, with the exception of sucking 15W40 engine oil through a tiny tube. Anyway, I woke up this morning and set out to sync the TBs – which were way out of sync. The culprit is quite likely on the title to the vehicle, in 9400 miles I never once bothered to check the sync on my TBs. Oops. All is well now, and both throttle bodies are within 1/16″ of 15W40 – what that is in inches of mercury I have no clue.
