Your chain appears to have even more play than mine, so I would say yes you need the next step chain rail. But I am no expert! I am under the impression that the BMW window is there so a shop mechanic can see the chain and if it can be forced above the arrow then he would drain the chain oil and...
No, with a flashlight and keen eyes you should be able to see how many holes are showing. The skewer was mostly to show how the holes are at a difficult angle to view, and they may be filled with oil. and it is jet black in there. So with the combination of the skewer and my eyes I was pretty...
Can the non hydraulic cam chain tensioner be replaced with the crankshaft in any position? The BMW manual attachment in post #3 has the engine turned to TDC requiring extra steps for the job but I don't see why that should matter if simply replacing one good (old) part with another (new) one.
I am finally doing preventative maintenance on my 2016 C650 Sport at 12,500 miles. Since I will have it apart for a new chain adjuster rail and CVT belt/rollers I decided to install a new BMW non hydraulic cam chain tensioner. An easy additional job with the plastic off. I believe this part...
I have been advised by getBMWparts.com that the tool will come from Germany and could take 4-6 weeks. Well, I am not in a hurry, but if it never comes I'll be in touch ;)
I had a look inside my swing arm this morning. I never saw pics quite like I took so I'll add them here.
In one pic I have inserted a bamboo skewer into the hole that denotes a first step chain rail. It is almost impossible to see that hole but it is there about 1/2" in.
The next two shots show...
That is very nice, thank you. I did find an OEM BMW tool for about $60 so I went ahead and bought that this morning :( I'm an impatient guy.
I did see your Reference :) FWIW the first enthusiast forum I ever joined was when I had a Husaberg 470, also blue and yellow (2001?) Long gone now but...
Is this it?

There are a lot or rollers out there and the Dr Pulley ones aren't round so I'm not too sure about them being for an OEM BMW variator. Thanks.
I looked at Dr Pulley Rollers for the C650 Sport. They range from 22g to 45g! I guess Malossi offers a lighter roller and different weights, Dr Pulley does not make 24g. I will look for the Malossi store next.
OK, good. Since my belt is 10 years old I will replace it. I saw the Easyboost YT video and saw that their tool set can do more than just the belt job. It may be my only option.
The rollers are another component that splits home mechanics between those who see a need to replace them and those...
