BMW F 800 ST Rehab: How to Check Valve Clearances (and replace spark plugs)

An MOA member who decided it was time to stop riding donated his 2008 BMW F 800 ST to the MOA Foundation to help further its cause of rider education, training and awareness. Unfortunately, the bike had been sitting for a couple of years before he reached that decision, so it needs a bit of rehab before it's ready for its next owner. In this video, we walk you through how to check the valve clearances, replacing the relevant gaskets along the way, and remove and replace the spark plugs. This job has some potential pain points, which George will identify and show you how to avoid problems as they come up. Tools needed: * Torx drivers + ratchet + extension * Torque wrench (for reassembly) Please visit the organizations and companies making this project possible: BMW MOA - https://www.bmwmoa.org BMW MOA Foundation - https://www.bmwmoaf.org Gridlock Motors: https://www.gridlockmotors.com Twisted Throttle/Denali Lights - https://www.twistedthrottle.com SW-MOTECH USA - https://sw-motech.us/en/
