2013 R1200RT approx. 21K miles. Purchased in September with 18.5K miles. Unknown service history as servicing dealer closed. I have been doing all needed maintenance to familiarize myself with the camhead (this replaced a 2005 RT) and decided to change spark plugs and check valves. Yesterday I measured using the lines on the exhaust cams to find TDC and measured in mm. 5 of the 8 were at or below low end tolerance, but my feeler gauges don't have as many mm steps as I'd like.
I just went out this morning, with my beautiful assistant and pillion, and remeasured, this time using a bamboo skewer to make sure we were at TDC. I also measured in 1/1000 inch instead of mm. Specs are INTAKE .005"-.009" EXHAUST .011"-.016". Here are the results: left top intake .005" left bottom intake ,005" left top exhaust .014" left bottom exhaust .012" right top intake .007" right bottom intake .004" right top exhaust .014" right bottom exhaust .011". So according to that, my right bottom intake is too tight and 4 more are really close to tight tolerance. I ordered another feeler gauge and will recheck again when it arrives.
My question is, what would cause these measurements to be so tight on a bike with just 21K? It runs great but does use some oil. Thanks! Robb
