We just did two Teneres in my garage this past weekend. Paul's bike (2015) was all in spec, but nearing the lower limit, so no adjustments needed yet. Hal's bike (2016) had two surprisingly tight exhausts. Intakes were in spec and the other two exhausts were like Paul's, nearing the tight end but still in spec. Both bikes were around 25K for their first check. I think we've solved the trouble to get the valve cover in and out, but getting the cover gasket sealed is still a bit of a pain. The other issue we ran into was re-setting the tensioner. Luckily I had a spare and it would wind in and allow us to set the clip without any trouble. Hal's tensioner however seemed to have the piston stuck in the second groove with the second clip. we just could not get it to wind in. We swapped in the spare in that case. I used a 12mm socket in a 3/8" drive impact wrench and was finally able to re-set it a couple of days later. There's no real impact imparted to the CCT because there's no solid engagement of the 12mm socket with the piston, but the slight vibration seem to be able to pop the piston past that bottom groove/clip and let it wind back in. We'll hang on to that extra tensioner for the next tech day. My bike will be due for it's third check in another 3-4,000 miles.
