But before Julio could head out again on his 790, the source of the developing oil leak needed to be found. He did have his backup 650, 'Bertha', in case, but with Rick on his 790, Julio preferred to be 790 mounted too. There's a few places that DR650s can leak oil from, the cam chain tensioner, aka CCT, gasket is one, and seemed a likely candidate this time, but no. Then LilSteve spotted it, it was the bolt out of the back of the CCT. Happily, it had fallen out and dropped down, wedging itself between the starter and crankcase. A little magnetic magic and it was retrieved and reinserted, sorted. Winner, and checking for leaks, just in case.
