The only difference in the procedure, from the left to the right, is the cam sensor trigger - it only exists on the left side and must be removed to access the exhaust cam retaining nut.

Are you saying there will be a "Cam alignment Tech Days" at the Limestone Ranch?

There is a good thread on this issue in the BMWLT forum, and Lee (LAF, also a member here) had done an excellent job of keeping statistics on how many of the "new" wetheads that he had taken apart had the cam timing off, from the factory!

What year is your bike? I am surprised to see the valve timing so far out!
Lee (LAF) on the LT forum has also found some to be out. I was curious to know why this is not being picked up at the relevant BMW Dealerships during their servicing.

2016 MY Andy and the timing really was not that far off.

There seems no rhyme or reason as to cam alignment or cam position sensor alignment.

I think I am at 11 or 12 now and there seems to be no correlation to model, RT, GS, GSA, or year.

I do know that the cam position sensor is the most noticeable if it is out. In the GS I follow for thousands of miles, his was way off and when we set it in place his starts became instant. No hesitation or false starts any longer like he was experiencing.

The cams being out do not show the same good results that are seen and felt.

I do suspect that it shows up in improved gas mileage and performance that can not be perceived by seat of the pants.

As to why it is not picked up more often dealers just do not check cam timing. You need to ask and you may get a blank stare. The thing is if you are in for a valve check a cam check takes like 5 mins more. If they need adjusted it is uninstalling a cam chain tensioner, installing a cam chain simulator, and using the alignment tool over the end of the cams.

I have had people from all over the country stop here in PA for me to check their cams and we check valves while we are there as it takes only a few mins more.

To me if something is supposed to be in a spec I want it there.

While my cams were only slightly out of phase, my bike starts noticeably faster than before. It used to always start with a pop and now it just lights up.
