Many people replace the "Doohickey" [Balancer Chain Adjuster Lever]. There was a time when the KLR 650 had an inadequately designed "Doohickey". The time frame of the known, problematic balancer levers began with the KLR 600, the predecessor to the KLR 650, and continued until the KLR 650 design change in the 2008 model. The early doohickey was made from two pieces of stamped steel with a very crude welding job that maintained tensions on the balancer chain system. There were many cases of broken components and broken welds, as well as tensioning spring failures. The springs broke, allowing the spring to float around the oil sump.Obviously, I'll get a Doohickey, but also a Thermo Bob?
Magnetic Oil plug? What else?
